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 on-board charge pump
circuitry generates fully compliant RS-232 voltage levels using small and inexpensive 0.1µF
charge pump capacitors. External +12V and -12V supplies are not required. The SP211E
and SP213E feature a low-power shutdown mode, which reduces power supply drain to
1µA. SP213E includes two receivers that remain active during shutdown to monitor for
signal activity.
The SP207E-SP213E devices are pin-to-pin compatible with our previous SP207, SP208,
SP211 and SP213 as well as industry-standard competitor devices. Driver output and re-
ceiver input pins are protected against ESD to over ±15kV for both Human Body Model and
IEC61000-4-2 Air Discharge test methods. Data rates of 120kbps are guaranteed, making
them compatible with high speed modems and PC remote-access applications. Receivers
also incorporate hysteresis for clean reception of slow moving signals.
