UPD4714A

Features:

 Conforms to EIA/TIA-232-E (RS-232C) standard
  +5 V single power source
  Threshold select pin selecting two types of threshold voltages
  Standby mode can be set by making standby pin high to reduce circuit current.
  Three-state output configuration.  Both driver and receiver outputs go into high-impedance state in standby mode.

Description

The PD4714A is a high-voltage silicon gate CMOS line dirver/reciever conforming to the EIA/TIA-232-E standard.It can operate with a single +5 V power source because it is provided with a DC-DC converter.  In addition, this linedriver/receiver has many ancillary functions, including output control, threshold select, and standby functions.Because the PD4714A is provided with three output driver circuits and five receiver circuits, it canconstitute an RS-232 interface circuit with a single chip.
