XR32330 Datasheet | MaxLinear

Description 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. 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 bined with Exar's driver architecture allow the XR32330 to deliver pliant 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 "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.
