Rev 8.00
October 15, 2014 +5V Powered, Dual RS-232 Transmitter/Receiver
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. Features The drivers feature true TTL/CMOS input compatibility,
slew-rate-limited output, and 300О© power-off source
impedance. The receivers can handle up to +30V, and have a
3kО© to 7kО© input impedance. The receivers also have
hysteresis to improve noise rejection. Low power consumption Meets all RS-232C and V.28 specifications Requires only single +5V power supply Onboard voltage doubler/inverter 2 drivers
