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.
