DATA SHEET MOS INTEGRATED CIRCUIT PD4722 RS-232 LINE DRIVER/RECEIVER AT 3.3 V/5 V The PD4722 is a high-breakdown voltage silicon gate CMOS line driver/receiver based on the EIA/TIA-232-E standard. The internal DC/DC converter can switch between multiple voltages, allowing it to operate with a single +3.3 V or +5 V power supply. It also provides standby function. This IC incorporates 4 driver circuits and 4 receiver circuits. An RS-232 interface circuit can be easily configured by connecting 5 capacitors externally. FEATURES * Conforms to EIA/TIA-232-E (former name, RS-232C) standards * Selectable +3.3 V/+5 V single power supply (selected by VCHA pin) * By setting the standby pin to a low level (standby mode), circuit current can be reduced. At such times, the driver output is in a high-impedance state. * Even in the standby mode, 2 receiver circuits can operate as inverters without hysteresis width. The other 2 circuits are fixed at a high level.

VDD and VSS are output pins stepped up internally. These pins should not be loaded directly. 2. Capacitors C1 to C5 with a breakdown voltage of 20 V or higher are recommended. And it is recommended to insert the capacitor that is 0.1 F to 1 F between VCC and GND. 3. If VCHA is kept low level (in 5 V mode), capacitor C5 is not necessary. 4. The pull-up resistors at driver input are active resistors. 2 PD4722 Truth Table Driver STBY D IN DOUT Remarks L x Z Standby mode (DC/DC converter is stopped) H L H Space level output H H L Mark level output Receiver R IN STBY R OUT EN Remarks R 3 to R 4 R 1 to R 2 R 3 to R 4 R 1 to R 2 L L x x H H Standby mode 1 (DC/DC converter is stopped) L H L x H H Standby mode 2 (DC/DC converter is stopped, R3 and R4 are operated) L H H x L H Standby mode 2 (DC/DC converter is stopped, R3 and R4 are operated) H x L H Mark level input H x H L Space level input 3 V 5 V switchingNote 5 VCHA Operating mode L 5 V mode (double step-up) H 3 V mode (3 times step-up) H: high-level, L: low-level, Z: high-impedance, x: H or L Note 5.

In low temperature (below 0 C), the capacitance of electrolytic capacitor becomes lower. Therefore, set higher values when using in low temperature. Concerning the wiring length between the capacitor and the IC, the shorter the better. Capacitors with good frequency characteristics such as tantalum capacitors, laminated ceramic capacitors, and aluminum electrolytic capacitors for switching power supply are recommended for the external capacitors. 4 PD4722 ELECTRICAL SPECIFICATIONS (TOTAL) (UNLESS OTHERWISE SPECIFIED, T A = -40 to +85 C, C 1 to C 5 = 1 F) Parameter Circuit Current Circuit Current Circuit Current at Standby (Standby Mode 1) Circuit Current at Standby (Standby Mode 2) Symbol I CC1 I CC2 I CC3 I CC4 MAX.

NEC Corporation assumes no responsibility for any errors which may appear in this document. NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual property rights of third parties by or arising from use of a device described herein or any other liability arising from use of such device. No license, either express, implied or otherwise, is granted under any patents, copyrights or other intellectual property rights of NEC Corporation or others. While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices, the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features. NEC devices are classified into the following three quality grades: "Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a customer designated "quality assurance program" for a specific application. The recommended applications of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device before using it in a particular application. Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems or medical equipment for life support, etc. The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books. If customers intend to use NEC devices for applications other than those specified for Standard quality grade, they should contact an NEC sales representative in advance. Anti-radioactive design is not implemented in this product. M4 96.5 16
