TI's customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 10.1 Application Information The DS26C31 is a quad differential line driver designed for applications that require long distance digital data transmission over balanced cables. The DS26C31 can be used in applications that require conversion from TTL or CMOS input levels to differential signal levels, compatible to RS-422. The use of complimentary signaling in a balanced transmission media provides good immunity in the midst of noisy environments or shifts in ground reference potential. 10.2 Typical Application Figure 28 depicts a typical implementation of the DS26C31x device in a RS-422 application. *RT is optional although highly recommended to reduce reflection. Figure 28. Two-Wire Balanced System, RS-422 10.2.1 Design Requirements * Apply TTL or LVCMOS signal to driver input lines INPUT A-D. * Transmit complementary outputs at OUTPUT A-D. * Use controlled-impedance transmission lines such as printed circuit board traces, twisted-pair wires or parallel wire cable. * Place a terminating resistor at the far end of the differential pair. 10.2.2 Detailed Design Procedure * Connect VCC and GND pins to the power and ground planes of the PCB with a 0.1-F bypass capacitor. * Use TTL/LVCMOS logic levels at INPUT A-D. * Use controlled-impedance transmission media for the differential output signals. * Place an optional terminating resistor at the far-end of the differential pair to avoid reflection. 14 Submit Documentation Feedback Copyright (c) 1998-2015, Texas Instruments Incorporated Product Folder Links: DS26C31M DS26C31T DS26C31M, DS26C31T www.ti.com SNLS375C - JUNE 1998 - REVISED JANUARY 2015 Typical Application (continued) 10.2.3 Application Curves Figure 29.

A 0.1-F bypass capacitor should be connect to the VCC pin such that the capacitor is as close as possible to the device. 12 Layout 12.1 Layout Guidelines The output differential signals of the device should be routed on one layer of the board, and clearance should be provided in order to minimize crosstalk between differential pairs that may be running in parallel over a long distance. Additionally, the differential pairs should have a controlled impedance with minimum impedance discontinuities and be terminated at the far-end, near the receiver, with a resistor that is closely matched to the differential pair impedance in order to minimize transmission line reflections. The differential pairs should be routed with uniform trace width and spacing to minimize impedance mismatching. 12.2 Layout Example Via to VCC Plane Input Via to GND Plane 16 1 Bypass Capacitor TX Differential Pair 2 15 3 14 4 13 Input TX Differential Pair Enable DS26C31M/DS26C31T TX Differential Pair Input 5 12 6 11 7 10 8 9 Enable TX Differential Pair Input Via to GND Plane Figure 31.

Designer represents that, with respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will thoroughly test such applications and the functionality of such TI products as used in such applications. TI's provision of technical, application or other design advice, quality characterization, reliability data or other services or information, including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, "TI Resources") are intended to assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any way, Designer (individually or, if Designer is acting on behalf of a company, Designer's company) agrees to use any particular TI Resource solely for this purpose and subject to the terms of this Notice. TI's provision of TI Resources does not expand or otherwise alter TI's applicable published warranties or warranty disclaimers for TI products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections, enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specifically described in the published documentation for a particular TI Resource. Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications that include the TI product(s) identified in such TI Resource. NO OTHER LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE TO ANY OTHER TI INTELLECTUAL PROPERTY RIGHT, AND NO LICENSE TO ANY TECHNOLOGY OR INTELLECTUAL PROPERTY RIGHT OF TI OR ANY THIRD PARTY IS GRANTED HEREIN, including but not limited to any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information regarding or referencing third-party products or services does not constitute a license to use such products or services, or a warranty or endorsement thereof. Use of TI Resources 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. TI RESOURCES ARE PROVIDED "AS IS" AND WITH ALL FAULTS. TI DISCLAIMS ALL OTHER WARRANTIES OR REPRESENTATIONS, EXPRESS OR IMPLIED, REGARDING RESOURCES OR USE THEREOF, INCLUDING BUT NOT LIMITED TO ACCURACY OR COMPLETENESS, TITLE, ANY EPIDEMIC FAILURE WARRANTY AND ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT OF ANY THIRD PARTY INTELLECTUAL PROPERTY RIGHTS. TI SHALL NOT BE LIABLE FOR AND SHALL NOT DEFEND OR INDEMNIFY DESIGNER AGAINST ANY CLAIM, INCLUDING BUT NOT LIMITED TO ANY INFRINGEMENT CLAIM THAT RELATES TO OR IS BASED ON ANY COMBINATION OF PRODUCTS EVEN IF DESCRIBED IN TI RESOURCES OR OTHERWISE. IN NO EVENT SHALL TI BE LIABLE FOR ANY ACTUAL, DIRECT, SPECIAL, COLLATERAL, INDIRECT, PUNITIVE, INCIDENTAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES IN CONNECTION WITH OR ARISING OUT OF TI RESOURCES OR USE THEREOF, AND REGARDLESS OF WHETHER TI HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949 and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements. Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use. Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S. TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product). Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications and that proper product selection is at Designers' own risk. Designers are solely responsible for compliance with all legal and regulatory requirements in connection with such selection. Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer's noncompliance with the terms and provisions of this Notice.
