HIN202E thru HIN241E
+/-15kV, ESD-Protected, +5V Powered,
RS-232 Transmitters/Receivers
The HIN202E-HIN241E family of RS-232 transmitters/receivers
interface circuits meet all ElA high-speed RS-232E and V.28
specifications, and are particularly suited for those applications
where
12V is not available. A redesigned transmitter circuit
improves data rate and slew rate, which makes this suitable for
ISDN and high speed modems. The transmitter outputs and
receiver inputs are protected to
15kV ESD (Electrostatic
Discharge). 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 HIN205E and
HIN235E 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 HIN205E, HIN206E, HIN211E, HIN213E, HIN235E,
HIN236E, and HIN241E feature a low power shutdown mode to
conserve energy in battery powered applications. In addition,
the HIN213E 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.
