DESCRIPTION

The

SP207E-SP213E are enhanced transceivers intended for use in RS-232 and V.28 se-

rial 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

SP211E and SP213E feature a low-power shutdown mode, which reduces

power supply drain to µA.

SP213E includes two receivers that remain active during shut-

down to monitor for signal activity.

The

SP207E-SP213E devices are pin-to-pin compatible with our previous SP207, SP208,

SP2 and SP23 as well as industry-standard competitor devices. Driver output and re-

ceiver 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.
