SP332 Datasheet | MaxLinear

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 Max Linear-patented charge pump allows 5V-only operation. FEATURES - - 5V only single supply operation - - Software programmable RS-232 or RS-485 selection - - 4 drivers, 4 receivers RS-232 - - 2 drivers, 2 receivers RS-485 - - Loop back function for self test - - 28-pin WSOIC package Typical Applications Circuit 0.1µF 0.1µF 0V 0V TTL/CMOS TTL/CMOS TTL/CMOS TTL/CMOS TTL/CMOS TTL/CMOS TTL/CMOS TTL/CMOS RS-232 Mode 5V 9 C1+ 5 VCC 0.1µF 12 C111 C2+ 13 C2- V+ 10 V+ 14 0.1µF 24 SEL A 23 LOOPBACK TTL/CMOS 2 26 SEL B TI1 400KΩ T1 TX1 6 RS-232 27...
