The
µ
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 line
driver/receiver has many ancillary functions, including output control, threshold select, and standby functions.
Because the
µ
PD4714A 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.
