Product Description:
Pericom Semiconductor’s PI5C series of logic circuits are produced
in the Company’s advanced submicron CMOS technology,
achieving industry leading performance.
The PI5C3861 is a 10-bit, 2-port bus switch designed with a low ON
resistance (5-ohm) allowing inputs to be connected directly to
outputs. The bus switch creates no additional propagation delay or
additional ground bounce noise. The switches are turned ON by the
Bus Enable (BE) input signal.
