• 5Ω switches connect inputs to outputs
• Direct bus connection when switches are ON
• Ultra Low Quiescent Power (0.1µA Typical)
– Ideally suited for notebook applications
• Packaging (Pb-free & Green available):
– 6-pin plastic S0T-23 (T)
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.
