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.
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 V
• By setting the standby pin to a low level (standby mode), circuit current can be reduced. At such times,
• Even in the standby mode, 2 receiver circuits can operate as inverters without hysteresis width.
Ordering Information
PD4723GS-GJG
The PD4723 is a high-breakdown voltage silicon gate CMOS line driver/receiver based on the EIA/TIA-232-E
This IC incorporates 3 driver circuits and 3 receiver circuits. An RS-232 interface circuit can be easily configured
the driver output is in a high-impedance state.
The other circuit is fixed at a high level.
