HIN232CB Datasheet

Interface - Drivers, Receivers, Transceivers


The HIN230-HIN241 (HIN232CB) 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 HIN232CB and HIN239) and feature onboard charge pump voltage converters which generate +10V and -10V supplies from the 5V supply. The HIN233 and HIN235 require no external capacitors and are ideally suited for applications where circuit board space is critical. The family of devices offer a wide variety of RS-232 transmitter/receiver combinations to accommodate various applications (see Selection Table).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.
