Description
Pericom Semiconductor’s PI5C3125 and PI5C3126 are 4-bit Bus
Switches designed with four individual 5Ω bus switches with fast
indiviual enables in an industry standard 74XX125/126 pinout.
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 PI5C3125 device has active LOW enables, and the PI5C3126
has active HIGH enables.
