2-Port Bus Switch with Individual Enables
Description
Pericom Semiconductor’s 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).
