DATA SHEET MOS INTEGRATED CIRCUIT µPD4711B RS-232 LINE DRIVER/RECEIVER The µPD4711B 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 µPD4711B is provided with two output driver circuits and two receiver ci
