PI5C3305
2-Bit Bus Switch with
Individual Enables
Features Description
Near-Zero propagation delay Pericom Semiconductors PI5C3305 is a 2-bit bus switch designed
with two individual 5 switches with fast individual enables. When
5 switches connect inputs to outputs
enabled via the associated Bus Enable (BE) pin, the A pin is
Direct bus connection when switches are ON
directly connected to the B pin for that particular gate. The bus
Ultra Low Quiescent Power (0.2A typical)
switch introduces no additional propagation delay or additional
Ideally suited for notebook applications
ground bounce noise.
Packaging (Pb-free & Green available):
The PI5C3305 device has active HIGH enables.
