UT232E

DESCRIPTION 

The UTC UT232E has two drivers and two receivers with dual 

charge-pump circuit. It meets RS-232D and V.28 specifications. Its 

high performance includes increased drive current for longer and 

more flexible cable configurations and 10V/µs slew rate, 120kbps

guaranteed transmission rate. For easier use, enhancements

include better ESD protection for RS-232 I/O pins, low power 

dissipation and four external small 0.1µF charge pump capacitors.

FEATURES 

* Single power supply: 3.3V~5.5V 

* Low power supply current: 3.0mA 

* Multiple drivers and receivers 

* Receiver input levels: ±25V 

* 3-State outputs of TTL/CMOS receiver 

* High output slew rate: 10V/µs under load 

* High data rate: 120kbps under load 

* Four external small charge pump capacitors: 0.1µF 

* Exceeds ±8KV HBM ESD protection for RS-232 I/O pins
