GENERAL DESCRIPTION

The XR32430EB and XR32431EB devices feature slew-rate limited outputs for reduced crosstalk and EMI. The XR32430EH and XR32431EH devices are optimized for mid speed applications, with data rates up to 460Kbps. The XR32430EU and XR32431EU devices are optimized for high speed designs with data rates up to 1Mbps, easily meeting the demands of high speed RS-232 applications. The XR32430/31 uses an internal high-efficiency charge-pump power supply that requires only four 0.1μF capacitors in 3.3V operation. This charge pump combined with Exar's driver architecture allow the XR32430/31 to deliver compliant RS-232 performance from a single power supply ranging from +3.0V to +5.5V. The AUTO ON-LINE® feature allows the device to automatically "wake-up" during a shutdown state when an RS-232 cable is connected and a connected peripheral is turned on. Otherwise, the device automatically shuts itself down drawing less than 1μA.
