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.F
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
A.
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,
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
IEC6000-4-2 Air Discharge test methods. Data rates of 20kbps 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.
