HIN230 thru HIN241
+5V Powered RS-232 Transmitters/Receivers
Description
The HIN230-HIN241 family of RS-232 transmitters/receivers
interface circuits meet all ElA RS-232C 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 features onboard charge pump volt-
age 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).
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.

Internally generated positive supply (+10V nominal), HIN231 and 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 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.
