Product Description
Pericom Semiconductor’s PI3C series of logic circuits are produced
using the Company’s advanced sub micron CMOS technology,
achieving industry leading speed grades.
The PI3C3125A and PI3C3126A are 2.5V or 3.3 Volt, 4-bit bus
switches designed with four individual 5Ω bus switches with fast
indiviual enables in an industry standard 74XX125/126 pinout.
When enabled via the associated Bus Enable (BE) 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 PI3C3126A
has active HIGH enables. It is very useful in switching signals that
have high bandwidth (>400 MHz).
