Description
The HIN232A high-speed RS-232 transmitter/receiver interface circuit meets all ElA high-speed RS-232E and V.28 specifications, and is particularly suited for those applications where 12V is not available. They require a single +5V power supply and feature 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 input, and have a 3k to 7k input impedance. The receivers also feature hysteresis to greatly improve noise rejection.
