DESCRIPTION
The SP207E-SP213E are 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 0.1µF 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.
