PI5C3303
SOTiny^™ 2:1 Mux/DeMux Bus Switch
Description
Pericom Semiconductor’s PI5C3303 is a single 2:1 Mux/DeMux
digital switch designed with a fast enable. When enabled using the
Bus Enable (BE) pin, the “A” or “B” pin is directly connected to
the “C” pin. The bus switch introduces no additional propagation
delay or additional ground bounce noise.
The PI5C3303 device has an active HIGH enable.
