RS-232 LINE DRIVER/RECEIVER AT 3.3 V/5 V
The µPD4721 is a high-breakdown voltage silicon gate CMOS line driver/receiver based on the EIA/TIA-232E standard. The internal DC/DC converter can switch between multiple voltages, realizing the allowing it to operate with a single +3.3 V or +5 V power supply. It als...
