GENERAL DESCRIPTION
The TC232 is a dual RS-232 transmitter/receiver that
complies with EIA /TIA RS-232E guidelines and is ideal for
all RS-232 communication links. This device operates from
a 5V power supply and contains two charge pump voltage
converters that produce ±10V power supplies.
The TC232 has four level translators. Two are RS-232
transmitters that convert TTL/CMOS input levels to 9V
RS-232 outputs. The other two translators are RS-232
receivers that convert RS-232 inputs to 5V TTL/CMOS
output levels. The receivers have a nominal threshold of
1.3V, a typical hysteresis of 0.5V, and can operate with
inputs up to ±30V.
