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.
