The SP207EH/208EH/211EH/213EH devices are high speed enhanced multi-channel RS-232 line transceivers with improved electrical performance. The SP207EH/208EH/ 211EH/213EH series is a superior drop-in replacement to our previous versions as well as popular industry standards. All devices feature low-power CMOS construction and the Sipex-patented (5,306,954) on-board charge pump circuitry that generates the +10V RS-232 voltage levels using 0.1F charge pump capacitors. The SP211E and SP213E devices feature a low-power shutdown mode, which reduces power supply drain to 1A. Enhancements to this series include a higher transmission 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 IEC1000-4-2 Air Discharge test methods.
