PD4712C/4712D
RS-232 LINE DRIVER/RECEIVER
The
碌
PD4712C and 4712D are 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
碌
PD4712C and 4712D are provided with four output driver circuits and four receiver
circuits, it can constitute an RS-232 interface circuit with a single chip.
FEATURES
鈥?Conforms to EIA/TIA-232-E (RS-232C) standard
鈥?+5 V single power source
鈥?Threshold select pin selecting two types of threshold voltages
鈥?Standby mode can be set by making standby pin high to reduce circuit current.
鈥?Three-state output configuration. Both driver and receiver outputs go into high-impedance state in standby mode.
