Description

Pericom Semiconductor’s PI3B16233 is a 16-bit to 32-bit mux/demux

switch. This device can be used for memory bank interleaving. The

PI3B16233 can be used as two 8-bit to 16-bit multiplexers or as one

16-bit to 32-bit multiplexer.

Two select inputs (SEL1 and SEL2) control the data flow. When the

TEST inputs are asserted HIGH, the A port is connected to both the

B1 and the B2 ports.
