Product Description
Pericom Semiconductor’s PI5C series of logic circuits are produced
using the Company’s advanced 0.6 micron CMOS technology.
The PI5C16211 is a 24-bit bus switch designed with a low ON
resistance allowing inputs to be connected directly to outputs. This
device operates as a 24-bit or a 12-bit bus switch, which provides
high speed bus switching.
