Description

Pericom Semiconductor’s PI3B3125 and PI3B3126 are 3.3 Volt, 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 PI3B3125 device has active LOW enables, and the PI3B3126 has active HIGH enables.
