Description
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 features 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 v ariety
of RS-232 transmitter/receiver combinations to accommodate
various applications (see Selection Table).
The drivers feature true TTL/CMOS input compatibility, slewrate-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.
Applications
• Any System Requiring RS-232 Communications Port
- Computer - Portable, Mainframe, Laptop
- Peripheral - Printers and Terminals
- Instrumentation
- Modems

Power Supply Input 5V ±10%. HIN233 and HIN235 5V ±5%.
V+ Internally generated positive supply (+10V nominal), HIN231 and HIN239 requires +7.5V to +13.2V.
V- Internally generated negative supply (-10V nominal).
GND Ground lead. Connect to 0V.
C1+ External capacitor (+ terminal) is connected to this lead.
C1- External capacitor (- terminal) is connected to this lead.
C2+ External capacitor (+ terminal) is connected to this lead.
C2- External capacitor (- terminal) is connected to this lead.
T
IN
Transmitter Inputs. These leads accept TTL/CMOS levels. An internal 400kΩ pull-up resistor to VCCis
connected to each lead.
T
OUT
Transmitter Outputs. These are RS-232 levels (nominally ±10V).
R
IN
Receiver Inputs. These inputs accept RS-232 input levels. An internal 5kΩ pull-down resistor to GND is connected
to each input.
R
OUT
Receiver Outputs. These are TTL/CMOS levels.
EN 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.
SD 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.
NC No Connect. No connections are made to these leads.
