MOS INTEGRATED CIRCUIT
PD4724
RS-232 LINE DRIVER/RECEIVER AT 3.3 V/5 V
The PD4724 is a high breakdown voltage silicon gate CMOS line driver/receiver based on the EIA/TIA-232-E standard. This IC features various functions, such as standby, and incorporates a DC/DC converter that switches boost multiples, enabling operation at both +3.3 V and +5 V single supply voltage. The PD4724 incorporates three drivers and five receivers, so an RS-232 interface circuit can be easily constructed by connecting five external capacitors. FEATURES * Based on EIA/TIA-232-E (RS-232-C) standard. * Single power supply: +3.3 V or +5 V (selectable with the VCHA pin) * Standby mode: Setting the standby pin to low level switches this IC into the standby mode and makes the driver outputs high-impedance. * Enable mode: When the enable pin is high level during the standby mode, two receivers can operate as inverters without hysteresis width (The other three receivers are fixed to high level).

Note The pull-up resistors of the driver inputs are active resistors. Remark 1. 2. 3. VDD and VSS are pins that output the voltage boosted internally. Don't connect these pins to the load. Capacitors with a breakdown voltage of 20 V or higher are recommended for C1 to C5. And it is recommended to insert the capacitor that is 0.1 F to 1 F between VCC and GND. The capacitor C5 does not have to be connected when the IC is used in 5 V mode (VCHA = L).

Note If the use of an electrolytic capacitor at low temperature is likely, set the capacitance with sufficient margin, because the capacitance of an electrolytic capacitor is smaller at lower temperatures (0 C or lower). Care must be taken to minimize the wiring length between the capacitor and this IC. Using capacitors of excellent high frequency characteristics (such as tantalum, multi-layer ceramic capacitors, and aluminum electrolytic capacitors for switching power supplies) is highly recommended.

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.
