The HIN202A-HIN241A family of high-speed RS-232 transmitters/receivers interface circuits meet all ElA high speed 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 and feature onboard charge pump voltage converters which generate +10V and -10V supplies from the 5V supply. The HIN205A and HIN235A require no external capacitors and are ideally suited for applications where circuit board space is critical. The family of devices offers a wide variety of high-speed RS-232 transmitter/receiver combinations to accommodate various applications (see Selection Table).
