DESCRIPTION
The SP211EH/213EH devices are high speed enhanced multi-channel RS-232 line transceiv-
ers 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. The SP211EH and SP213EH devices feature a low-power shutdown mode, which
reduces power supply drain to 1µA. Enhancements to this series include a higher transmis-
sion rate of 500kbps, a lower power supply current at 3mA typical (no load), and superior
ESD performance. The ESD tolerance has been improved for this series to over +/-15kV for
both Human Body Model and IEC61000-4-2 Air Discharge test methods.
