+5V Powered RS-232
Transmitters/Receivers
The HIN230-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
HIN231 and HIN239) and feature onboard charge pump
voltage converters which generate +10V and -10V supplies
from the 5V supply. The HIN233 and HIN235 require no
external capacitors and are ideally suited for applications where
circuit board space is critical. 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 require +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 SHUTDOWN = 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.
