SP332
RS-232/RS-485 Multi-Mode Serial Transceiver
s +5V-Only Single Supply Operation
s 4 Drivers, 4 Receivers RS-232
s 2 Drivers, 2 Receivers RS-485
s Loop Back Function for Self Test
s 28 Pin SOIC Packaging
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 input pins. The device also includes a loop back function which internally
connects driver outputs to receiver inputs for a chip self test. A Sipex-patented charge pump
(5,306,954) allows +5V-only operation.
