SP207ET-L

• Product Introduction

  Meets all EIA-232 and ITU V.28 specifications     Single +5 V supply operation     Typical quiescent current is 3mA     4 x 0.1μF external charge pump capacitors     Typical 230kbps transfer rate     Standard SOIC and SSOP footprints     1μA Shutdown Mode (SP211E and SP213E)     Two Wake Receivers (SP213E)     Tri-State/RxEnable (SP211E and SP213E)     Improved ESD specifications:         ± 15kV mannequin         Features ± 15kV IEC1000-4-2 air-gapped discharge         With ± 8kV IEC1000-4-2 Contact Discharge Description The SP207E, SP213E is an enhanced transceiver for use in RS-232 and V.28 selenium rials. These devices have very low power consumption, and the single supply operation makes them ideal for space-constrained applications. Exar's patented (5306954) on-board charge pump circuitry produces a fully compatible RS-232 voltage rating 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 monitoring signal activity. The SP207E, SP213E device pin-to-pin compatible competitors with our previous SP207, SP208, SP211 and SP213 as well as industry standard devices. ESD protection of the driver output and rereceiver input pins in excess of ± 15kV for mannequins and IEC1000-4-2 air-gapped discharge test methods. Guaranteed to exceed 120kbps and 230kbps typical, making them compatible with high-speed modems and PC remote access applications. The receiver also incorporates cleaning of slow-moving signal reception lag
