DESCRIPTION
The SP207E-SP213Eare enhanced transceivers intended for use in RS-232 and V.28 serial communication. These devices feature very low power consumption and single-supply
operation making them ideal for space-constrained applications. Exar-patented (5,306,954)
on-board charge pump circuitry generates fully compliant RS-232 voltage levels using small
and inexpensive 0.µF charge pump capacitors. External +2V and -2V supplies are not
required. The SP211Eand SP213Efeature a low-power shutdown mode, which reduces power supply drain to µA. SP213Eincludes two receivers that remain active during shut down to monitor for signal activity.

■  Meets All EIA-232 and ITU V.28 Specifications
■  Single +5V Supply Operation
■  3mA Typical Static Supply Current
■  4 x 0.1μF External Charge Pump Capacitors
■  Typical 230kbps Transmission Rates
■  Standard SOIC and SSOP Footprints
■  1μA Shutdown Mode (SP211E & SP213E)
■  Two Wake-Up Receivers (SP213E)
■  Tri-State/RxEnable (SP211E & SP213E)
■  Improved ESD Specifications:
    +5kV Human Body Model
    +5kV IEC000-4-2 Air Discharge
    +8kV IEC000-4-2 Contact Discharge
The SP207E-SP213Edevices are pin-to-pin compatible with our previous SP207, SP208, SP2 and SP23 as well as industry-standard competitor devices. Driver output and receiver input pins are protected against ESD to over ±5kV for both Human Body Model and IEC000-4-2 Air Discharge test methods. Data rates of over 20kbps are guaranteed with 230kbps typical, making them compatible with high speed modems and PC remote-access applications.   Receivers  also  incorporate  hysteresis  for  clean  reception  of  slow  moving signals.
