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 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.
