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,
SP2ꢀꢀ and SP2ꢀ3 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
IECꢀ000-4-2 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.
