The HIN202E-HIN241E family of 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. A redesigned transmitter circuit improves data rate and slew rate, which makes this suitable for ISDN and high speed modems.
