HIN230 thru HIN241

+5V Powered RS-232

Transmitters/Receivers

The HIN230-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

HIN231 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, 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.
