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 +/- 0V RS-232 voltage levels using 0.F charge pump capacitors. The SP211EH and SP213EH devices feature a low-power shutdown mode, which reduces power supply drain to A. 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 +/- 5kV for both Human Body Model and IEC6000-4-2 Air Discharge test methods.
