The SP211EH/213EH devices are high speed enhanced multi-channel RS-232 line transceivers with improved electrical performance. The SP211EH/213EH series is a superior drop-in replacement to our previous versions as well as popular industry standards. All devices fea- ture very low power CMOS construction and the Exar-patented (5,306,954) on-board charge pump circuitry that generates the +/-10V RS-232 voltage levels using 0.1µF charge pump capacitors.
