+5V Powered RS-232
Transmitters/Receivers
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
The family of devices offer a wide variety of RS-232
transmitter/rec eiver c ombinations to accomm odate various
applications (see Selection Table).
The drivers feature true TTL/ CMOS input compati bili ty, slewrate-limited output, and 300Ω power-off source imp edance.
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.
-10V supplies from the 5V supply.
