The SP202E, SP232E, SP233E, SP310E and SP312E devices are a family of line driver and receiver pairs that meets the specifications of RS-232 and V.28 serial protocols. The devices are pin-to-pin compatible with MaxLinear's SP232A, SP233A, SP310A and SP312A devices as well as popular industry standard pinouts. The ESD tolerance has been improved on these devices to over +/-15kV for Human Body Model. This series offer a 120kbps data rate under load, small ceramic type 0.1µF charge pump capacitors and overall ruggedness for commercial applications. Features include MaxLinear's BiCMOS design which allowing low power operation without sacrificing performance. The series is available in lead free packages with commercial and industrial temperature ranges.

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)
