• 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.

Notes:
1. This parameter is guaranteed but not tested on Propagation Delays.
2. The bus switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The
time constant for the switch alone is of the order of 0.25ns for 50pF load. Since his time constant is much smaller than the rise/fall times of
typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in a system is
determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side.
3. See test circuit and waveforms.
