Product Description
Pericom’s Semiconductor’s PI3C series of logic circuits are
produced using the Company’s advanced submicron CMOS
technology, achieving industry leading performance.
The PI3C3861 is a 10-bit, 2.5V or 3.3 volt, 2-port bus switch
designed with a low ON-Resistance (5Ω) 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. This device is very userful in switching signals that have
high bandwidth (>400 MHz).
