Product Description

The PI3C3126 is a 2.5 volt or 3.3 volt, 4-bit bus switch designed with four individual 5-ohm bus switches with fast indiviual enables in an industry standard 74XX125/126 pinout. When enabled via the associated Bus Enable 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 PI3C3126 has active HIGH enables. It is very useful in switching signals that have high bandwidth (>400 MHz).
