UPD4713A

DATA SHEET MOS INTEGRATED CIRCUIT µPD4713A RS-232 LINE DRIVER/RECEIVER The µPD4713A is a high-voltage silicon gate CMOS line driver/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 µPD4713A is provided with three output driver circuits and three receiver circuits, it can constitute an RS-232 interface circuit with a single chip. 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.
