HIN202A thru HIN241A
High Speed +5V Powered RS-232
Transmitters/Receivers
The HIN202A-HIN241A family of high-speed RS-232
transmitters/receivers interface circuits meet all ElA high-
speed RS-232E and V.28 specications, and are particularly
suited for those applications where
±12V is not available.
They require a single +5V power supply and feature onboard
charge pump voltage converters which generate +10V and
-10V supplies from the 5V supply. The HIN203A, HIN205A,
HIN233A and HIN235A require no external capacitors and
are ideally suited for applications where circuit board space
is critical. The family of devices offers a wide variety of high-
speed RS-232 transmitter/receiver combinations to
accommodate various applications (see Selection Table).
The HIN205A, HIN206A, HIN211A, HIN213A, HIN235A,
HIN236A, and HIN241A feature a low power shutdown mode
to conserve energy in battery powered applications. In
addition, the HIN213A provides two active receivers in
shutdown mode allowing for easy “wakeup” capability.
The drivers feature true TTL/CMOS input compatibility, slew
rate-limited output, and 300
power-off source impedance.
The receivers can handle up to
±30V input, and have a 3k
to 7k
input impedance. The receivers also feature
hysteresis to greatly improve noise rejection.
