SP332
SP332 is RS-232/RS-485 Multi-mode SerialTransceiver manufactured by Exar.
DESCRIPTION
The SP332 is a monolithic device that contains both RS-232 and RS-485 line drivers and receivers. The configuration of the SP332 can be changed at any time by changing the logic state of two control pins. The device also includes a loop back function which internally connects driver outputs to receiver inputs for a chip self test. An Exar-patended charge pump allows +5V-only operation.
