Product Description
Pericom Semiconductor’s PI3C series of bus switch circuits are
produced using the Company’s advanced submicron CMOS
technology.
The PI3C16211 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.
