PI3C3125
2.5V/3.3V, High Bandwidth, Hot Insertion,4-Bit,
2-Port Bus Switch with Individual Enables
Description
Pericom Semiconductor’s PI3C3125 IS A 2.5 volt or 3.3 volt,
4-bit busswitch designed with four individual 5-ohm bus switches
with fast individual 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 devicehasactive LOW enables. It is very useful
in switching signals that have high bandwidth (>400 MHz).
