UPD4714A RS-232 LINE DRIVER/RECEIVER

DATA SHEET MOS INTEGRATED CIRCUIT µPD4714A RS-232 LINE DRIVER/RECEIVER The µPD4714A 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 line driver/receiver has many ancillary functions, including output control, threshold select, and standby functions. Because the µPD4714A is provided with three output driver circuits and five receiver.

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
