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 combined with MaxLinear's driver architecture allow the XR32330 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 "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.

For RS-232 it is 50 feet (15 meters), or the cable length equal to a capacitance of 2500 pF, at a maximum transmission rate of 19.2kbps. When we reduce the baud rate, it allows for longer cable length. For Example:
Baud Rate (bps)
Maximum RS-232 Cable Length (ft)
