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). The drivers feature true TTL/CMOS input compatibility, slewrate-limited output, and 300 power-off source impedance. The receivers can handle to ±30V, and have to 7k input impedance. The receivers also feature hysteresis to greatly improve noise rejection.

An internal 400k pull-up resistor to VCC 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 5k 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 = 5V, the receiver outputs are placed in a high impedance state. Shutdown Input. With = 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. FUNCTION
