standard. This IC features various functions, such as standby, and incorporates a DC/DC converter that switches boost
multiples, enabling operation at both +3.3 V and +5 V single supply voltage.
by connecting five external capacitors.
FEATURES
• Based on EIA/TIA-232-E (RS-232-C) standard.
• Single power supply: +3.3 V or +5 V (selectable with the V
• Standby mode: Setting the standby pin to low level switches this IC into the standby mode and makes
• Enable mode: When the enable pin is high level during the standby mode, two receivers can operate as inverters
ORDERING INFORMATION
PD4724GS-GJG
The PD4724 is a high breakdown voltage silicon gate CMOS line driver/receiver based on the EIA/TIA-232-E
The PD4724 incorporates three drivers and five receivers, so an RS-232 interface circuit can be easily constructed
the driver outputs high-impedance.
without hysteresis width (The other three receivers are fixed to high level).
