Copyright (c) 1992-2005, Texas Instruments Incorporated SN74LVC244A OCTAL BUFFER/DRIVER WITH 3-STATE OUTPUTS www.ti.com SCAS414X - NOVEMBER 1992 - REVISED MARCH 2005 DESCRIPTION/ORDERING INFORMATION (CONTINUED) The SN74LVC244A is organized as two 4-bit line drivers with separate output-enable (OE) inputs. When OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in a mixed 3.3-V/5-V system environment. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. The input and output negative-voltage ratings may be exceeded if the input and output current ratings are observed. The value of VCC is provided in the recommended operating conditions table. The package thermal impedance is calculated in accordance with JESD 51-7. The package thermal impedance is calculated in accordance with JESD 51-5. For the DW package: above 70C the value of Ptot derates linearly with 8 mW/K. For the DB, DGV, N, NS, and PW packages: above 60C the value of Ptot derates linearly with 5.5 mW/K. 3 SN74LVC244A OCTAL BUFFER/DRIVER WITH 3-STATE OUTPUTS www.ti.com SCAS414X - NOVEMBER 1992 - REVISED MARCH 2005 Recommended Operating Conditions (1) TA = 25C VCC Supply voltage VIH VIL High-level input voltage Low-level input voltage VI Input voltage VO Output voltage IOH High-level output current Operating Data retention only VCC = 1.65 V to 1.95 V (1) 4 Low-level output current -40 TO 125C MIN MAX MIN MAX MIN MAX 1.65 3.6 1.65 3.6 1.65 3.6 1.5 1.5 1.5 0.65 x VCC 0.65 x VCC 0.65 x VCC VCC = 2.3 V to 2.7 V 1.7 1.7 1.7 VCC = 2.7 V to 3.6 V 2 2 2 VCC = 1.65 V to 1.95 V UNIT V V 0.35 x VCC 0.35 x VCC 0.35 x VCC VCC = 2.3 V to 2.7 V 0.7 0.7 0.7 VCC = 2.7 V to 3.6 V 0.8 0.8 0.8 V 0 5.5 0 5.5 0 5.5 V 0 VCC 0 VCC 0 VCC V VCC = 1.65 V -4 -4 -4 VCC = 2.3 V -8 -8 -8 VCC = 2.7 V -12 -12 -12 VCC = 3 V -24 -24 -24 4 4 4 VCC = 1.65 V IOL -40 TO 85C VCC = 2.3 V 8 8 8 VCC = 2.7 V 12 12 12 VCC = 3 V 24 24 24 All unused inputs of the device must be held at VCC or GND to ensure proper device operation.

TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.

Falls within JEDEC MO-150 POST OFFICE BOX 655303 * DALLAS, TEXAS 75265 IMPORTANT NOTICE Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other changes to its semiconductor products and services per JESD46C and to discontinue any product or service per JESD48B. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as "components") are sold subject to TI's terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI's terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers' products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers' products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI's goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or "enhanced plastic" are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such components to meet such requirements.
