UPD4723 Description
DATA SHEET MOS INTEGRATED CIRCUIT µPD4723 RS-232 LINE DRIVER/RECEIVER AT 3.3 V/5 V The µPD4723 is a high-breakdown voltage silicon gate CMOS line driver/receiver based on the EIA/TIA-232-E standard. The internal DC/DC converter can switch between multiple voltages, allowing it to operate with a single +3.3 V or +5 V power supply. It also provides standby function.
UPD4723 Key Features
- Conforms to EIA/TIA-232-E (former name, RS-232C) standards
- Selectable +3.3 V/+5 V single power supply (selected by VCHA pin)
- By setting the standby pin to a low level (standby mode), circuit current can be reduced. At such times, the driver outp
- Even in the standby mode, 2 receiver circuits can operate as inverters without hysteresis width. The other circuit is fi
