DESCRIPTION The ST207EH is a high speed enhanced multi-channel RS-232 line transceivers with improved electrical performance. The ST207EH is a superior drop-in replacement to our previous versions as well as popular industry standards. The device feature low-power CMOS construction and the charge pump circuitry that generates the 10V RS-232 voltag elevels using 01F charges pump capacitors. The ST207EH include a high transmission rate of 500Kbps, a lower supply current at 1.5mA typical (no load), and a superior ESD performance. The ESD tolerance has been ORDERING CODES
