HIN232A

High Speed +5V Powered RS-232 Transmitters/Receivers

Product Status: Mass Production(*)

OVERVIEW

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 300Ω power-off source impedance. The receivers can handle up to ±30V input, and have a 3kΩ to 7kΩ input impedance. The receivers also feature hysteresis to greatly improve noise rejection.
