PI3C3126
2.5V/3.3V, High Bandwidth, Hot Insertion,4-Bit,
2-Port Bus Switch with Individual Enables
Description
Pericom Semiconductor’s 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).
