Description
Pericom Semiconductor’s PI3C3305 and PI3C3306 are 2.5 volt or
3.3 volt, 2-bit bus switches designed 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 PI3C3306 device has active LOW enables, and the PI3C3305
has active HIGH enables. It is very useful in switching signals that
have high bandwidth (>400 MHz).
