HIGH PERFORMANCE RS-232

LINE DRIVERS/RECEIVERS



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
