SP332

RS-232/RS-485 Multi-Mode Serial Transceiver

■ +5V-Only Single Supply Operation

■ 4 Drivers, 4 Receivers RS-232

■ 2 Drivers, 2 Receivers RS-485

■ Loop Back Function for Self Test

■ 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.
