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.
