描述 Description

The SP208EH/211EH/213EH devices are high speed enhanced multi-channelRS-232 line transceivers with improved electrical performance. TheSP208EH/211EH/213EH series is a superior drop-in replacement to ourprevious versions as well as popular industry standards. All devicesfeature very low power CMOS construction and the Exar-patented(5,306,954) on-board charge pump circuitry that generates the +/-10VRS-232 voltage levels using 0.1μF charge pump capacitors. The SP211EHand SP213EH devices feature a low-power shutdown mode, which reducespower supply drain to 1μA. Enhancements to this series include a highertransmission rate of 500kbps, a lower power supply current at 3mAtypical (no load), and superior ESD performance. The ESD tolerance hasbeen improved for this series to over +/-15kV for both Human Body Modeland IEC61000-4-2 Air Discharge test methods.For technical support or help choosing a product please email Exar’s Serial Technical Support group at:?serialtechsupport@exar.com.
