HIN232CPZ

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).

The drivers feature true TTL/CMOS input compatibility, slew-

rate-limited output, and 300

Ω 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
