Description
Diodes’ PI3C3125 and PI3C3126 are 2.5 volt or 3.3 volt, 4-bit
bus switches 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 PI3C3125 device has active LOW enables, and the PI3C3126
has active HIGH enables. It is very useful in switching signals that
have high bandwidth (>400 MHz).
