Product Description
Pericom’s Semiconductor’s PI3B series of logic circuits are
produced using the Company’s advanced sub micron CMOS
technology, achieving industry leading performance.
The PI3B3863 is a 10-bit, 3.3 volt two-port bus switch designed
with a low ON resistance allowing inputs to be connected
directly to outputs. The bus switch creates no additional
propagational delay or additional ground bounce noise. The
switches are turned ON by the Bus Enable (BE) input signal,
which is SSTL-2 compatible.
