MOS INTEGRATED CIRCUIT
µPD4722
RS-232 LINE DRIVER/RECEIVER AT 3.3 V/5 V
The µPD4722 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.
This IC incorporates 4 driver circuits and 4 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 standby pin to a low level (standby mode), circuit current can be reduced. At such times, the driver
output is in a high-impedance state.
• Even in the standby mode, 2 receiver circuits can operate as inverters without hysteresis width.
The other 2 circuits are fixed at a high level.
