Description
Pericom Semiconductor’s PI5C32160C is a 16 to 32-bit
demultiplexer bus switch. Industry leading advantages include
a propagation delay of 250ps, resulting from 5Ω channel
resistance, and low I/O capacitance. A port demultiplexes to
either 1B and 2B or to both. The switch is bidirectional.
Application
Provides PCI Hot-Plugging
