UPD4711B Description
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.
UPD4711B Key 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
