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 con-
nects driver outputs to receiver inputs for a chip self test. An
Exar-patended charge pump
allows +5V-only operation.
