+5V Powered RS-232 Transmitters/Receivers
FN3138 Rev 17.00 August 6, 2015
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 (see “Selection Table” on page 1).
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 feature hysteresis to greatly improve noise rejection.
