illustrate
The SP207E, SP213E is an enhanced transceiver used in RS-232 and V.28 selenium rial communications.These devices have very low power consumption and single-supply operation make them ideal for space-constrained applications.Exar's patented (5306954) on-board charge pump circuit produces a fully compatible RS-232 voltage level using a small and inexpensive charge pump capacitor of 0.1μF.External +12 V and -12V power supplies are not required.The SP211E and SP213E feature a low-power shutdown mode that reduces power consumption to 1μA.The SP213E includes two receivers that are still active in shutdown to monitor signal activity.

The SP207E, SP213E device pin-to-pin is compatible with our previous SP207, SP208, SP211 and SP213 as well as industry-standard devices from competitors.ESD protection of driver output and rereceiver input pins exceeds ± 15kV for human body models and IEC1000-4-2 air gap discharge test method.Data transfer rates over 120kbps and 230kbps typical are guaranteed, making them compatible with high-speed modems and PC remote access applications.The receiver also incorporates cleanup of slow-selling signal reception hysteresis
