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.
