The ICL232 is a dual RS-232 transmitter/receiver interface circuit that meets all ElA RS-232C and V.28 specifications. It requires a single +5V power supply, and features two onboard charge pump voltage converters which generate +10V and -10V supplies from the 5V supply. 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 have hysteresis to improve noise rejection.
The ICL232 is a dual RS‑232 transmitter/receiver interface that requires only a single +5 V power supply. It includes onboard charge‑pump voltage converters that generate +10 V and –10 V, provides true TTL/CMOS input compatibility, and offers low power consumption.
Typical applications include any RS‑232 data terminal or communication link where a +12 V supply is unavailable. The device is offered in PDIP, CERDIP, and SOIC packages for commercial, industrial, and military temperature ranges.
