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, 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.
The HIN232‑HIN241 family of RS‑232 transmitters/receivers are +5 V powered devices that meet all EIA RS‑232E and V.28 specifications. They generate ±10 V supplies internally, offer low power consumption, and support a wide range of transmitter/receiver configurations.
The document includes pin descriptions, detailed pinout diagrams, absolute maximum ratings, electrical specifications, ordering information, and package dimensions for the various device variants.
| Supply Voltage | +5 V (single supply) |
|---|---|
| V+ Voltage Range | 0 V to 13.2 V |
| Receiver Input Voltage Range | -30 V to +30 V |
| Supply Current (typical) | 7‑15 mA (HIN236‑HIN238, HIN240‑HIN241) |
| Shutdown Supply Current | 1‑10 pA |
The devices operate from a single +5 V supply (except HIN239 which also supports +7.5 V to +13.2 V).
The receiver inputs accept voltages from –30 V to +30 V.
Typical supply current is 7‑15 mA for most variants, while HIN239 draws about 0.4‑1 mA.
The shutdown supply current is between 1 pA and 10 pA.
