HIN232

+5V Powered RS-232 Transmitters/Receivers

OVERVIEW

The HIN232-HIN241 family of RS-232 transmitters/receivers interface circuits meet all ElA RS-232E and V.28 specifications, and are particularly suited for those applications where ±12V is not available. They require a single +5V power supply (except HIN239) and feature onboard charge pump voltage converters which generate +10V and -10V supplies from the 5V supply. The family of devices offer a wide variety of RS-232 transmitter/receiver combinations to accommodate various applications.

The drivers feature true TTL/CMOS input compatibility, slewrate- limited output, and 300Ω power-off source impedance. The receivers can handle up to ±30V, and have a 3kΩ to 7kΩ input impedance. The receivers also feature hysteresis to greatly improve noise rejection.
