PI5C3305
2-Bit Bus Switch with
Individual Enables
Description
Pericom Semiconductor’s PI5C3305 is a 2-bit bus switch designed
with two individual 5Ω switches with fast individual enables. When
enabled via the associated Bus Enable (BE) pin, the “A” pin is
directly connected to the “B” pin for that particular gate. The bus
switch introduces no additional propagation delay or additional
ground bounce noise.
The PI5C3305 device has active HIGH enables.

Notes:
1. H = High Voltage Level, L = Low Voltage Level
Hi-Z = High Impedance, X = Don’t Care
2. A pull-up resistor should be provided for power-up protection.
