Product Summary

The HIN232ACB is a high-speed RS-232 transmitter/receiver interface circuit. It meets all ElA high-speed RS-232E and V.28 specifications, and is particularly suited for those applications where ±12V is not available. The HIN232ACB requires a single +5V power supply and feature onboard charge pump voltage converters which generate +10V and -10V supplies from the 5V supply. The applications of the HIN232ACB include Portable, Mainframe, Laptop, Printers and Terminals, Instrumentation, UPS, Modems.

Parametrics

HIN232ACB absolute maximum ratings: (1)VCC to Ground:(GND -0.3V) <VCC < 6V; (2)V+ to Ground:(VCC -0.3V) <V+ < 12V; (3)V- to Ground:-12V < V- < (GND +0.3V); (4)Input Voltages: TIN:-0.3V < VIN < (V+ +0.3V), RIN:±30V; (5)Output Voltages: TOUT:(V- -0.3V) < VTXOUT < (V+ +0.3V), ROUT:(GND -0.3V) < VRXOUT < (V+ +0.3V); (6)Short Circuit Duration: TOUT:Continuous, ROUT:Continuous.
