µPD4724
RS-232 LINE DRIVER/RECEIVER AT 3.
3 V/5 V
The µPD4724 is a high breakdown
voltage silicon gate
CMOS line driver/receiver based on the EIA/TIA-232-E 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.
The µPD4724 incorporates three drivers and five receivers, so an RS-232 interface circuit can be easily constructed 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 VCHA pin) • Standby mode: Setting the stan...
