+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 -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” on page 1).
The drivers feature true TTL/CMOS input compatibility,
slew-rate-limited output, and 300Ω 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.

Power Supply Input 5V ±10%.
Internally generated positive supply (+10V nominal), HIN239 requires +7.5V to +13.2V.
Internally generated negative supply (-10V nominal).
Ground lead. Connect to 0V.
External capacitor (+ terminal) is connected to this lead.
External capacitor (- terminal) is connected to this lead.
External capacitor (+ terminal) is connected to this lead.
External capacitor (- terminal) is connected to this lead.
Transmitter Inputs. These leads accept TTL/CMOS levels. An internal 400kΩ pull-up resistor to
V
CC
is connected to each lead.
Transmitter Outputs. These are RS-232 levels (nominally ±10V).
Receiver Inputs. These inputs accept RS-232 input levels. An internal 5kΩ pull-down resistor to GND is connected to each input.
Receiver Outputs. These are TTL/CMOS levels.
Enable input. This is an active low input which enables the receiver outputs. With EN = 5V, the receiver outputs are placed
in a high impedance state.
Shutdown Input. With SD = 5V, the charge pump is disabled, the receiver outputs are in a high impedance state and the
transmitters are shut off.
No Connect. No connections are made to these leads.
