+5V Powered RS-232 Transmitters/Receivers
The HIN231-HIN241 family ofRS-232 transmitters/receivers interface ci rcui tsmeet allElA RS-232E and V.28 specifications, and areparticularly suited for t hoseapplications where ±12V is not available. They require asingle +5V power supply (except HIN231 and HIN239)and feature onboard charge pump voltage converters which generate +10V and -10V supplies from t he5V supply. The f amilyof devicesoffer a wide variety of RS-232transmitter/receivercombinationsto 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 i mpedance. The receivers also feature hysteresis to greatly improve noise rejection.
File Number 3138.10

SHUTDOWN Shutdown Input. With SHUTDOWN = 5V, the charge pump is disabled, the receiver outputs are in a high impedance state
NC No Connect. No connectionsare made to these leads.
Power Supply Input 5V ±10%.
Transmitter Inputs. These leads accept TTL/CMOS levels. An internal 400kΩ pull-up resistor to VCCis connected to each lead. TransmitterOutputs. 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 placedin a high
impedance state.
and the transmitters are shut off.
