+5V Powered RS-232
Transmitters/Receivers
The HIN231-HIN241 family of RS-232 transmitters/receivers
interface circuitsmeet 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 family of devices offer a wide variety of
RS-232 transmitter/receiver combinations to accommodate
various applications (see Selection Table).
