MOS INTEGRATED CIRCUIT
µP D 4 7 2 1
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 also provides standby function.
This IC incorporates 2 driver circuits and 2 receiver circuits.
An RS-232 interface circuit can be easily configured by connecting 5 capacitors externally.
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...
