Product Description
Pericom Semiconductor’s PI5C16212 is a 24-bit bus exchange
switches designed with a low On-Resistance allowing inputs to be
connected directly to outputs. This device operates as a 24-bit bus
switch or a 12-bit exchanger that provides data exchanging between
the four signal ports via the data select pins (S0-S2).
