Description

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.

Applications

    • Any System Requiring RS-232 Communication Ports
      • Computer - Portable, Mainframe, Laptop
      • Peripheral - Printers and Terminals
      • Instrumentation
      • Modems

Design Tip

I see many manufacturers offer "+/-15kV ESD Protected" (or "High ESD") products. Does this mean that they all have the same level of protection?
