XR32330EBERTR-F

XR32330 3-Driver/3-Receiver Intelligent RS-232 Transceiver with 1.65V-5.5V Interface General Description FEATURES The XR32330 product is a 3-driver/ 3-receiver RS-232 transceiver featuring a variable low voltage logic interface, down to 1.65V. This product is intended for portable or hand-held applications such as bar code scanners as well as point-of-sales terminals, security and industrial control applications. The XR32330EBER device features slew-rate limited outputs for reduced crosstalk and EMI. • Meets true EIA/TIA-232-F Standards from a +3.0V to 5.5V power supply •1.65V to 5.5V Logic Interface VL pin • AUTO ON-LINE circuitry automatically wakes up from a 1mA shutdown • Regulated Charge Pump yields stable RS-232 Outputs regardless of VCC variations The XR32330 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 XR32330 to deliver compliant RS-232 performance from a single power supply ranging from +3.0V to +5.5V. • Enhanced ESD Specifications • ±15kV Human Body Model • ±15kV IEC61000-4-2 Air Discharge • ±8kV IEC61000-4-2 Contact Discharge • 250Kbps min transmission rate (speed grade B) • -40°C to 85°C ambient operating temperature • Lead-free (RoHS 6) QFN package The AUTO ON-LINE® feature allows the device to automatically "wakeup" 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.
