Description
The ICL232 is a dual RS-232 transmitter/receiver interface
circuit that meets all ElA RS-232C and V.28 specifications. It
requires a single +5V power supply, and features two
onboard charge pump voltage converters which generate
+10V and -10V supplies from the 5V supply.
The drivers feature true TTL/CMOS input compatibility, slew-
rate-limited output, and 300
power-off source impedance.
The receivers can handle up to +30V, and have a 3k
to 7k
input impedance. The receivers also have hysteresis to
improve noise rejection.
