Product Description
Pericom Semiconductor聮s PI5C series of logic circuits are produced
using the Company聮s advanced 0.8 micron CMOS technology,
achieving industry leading speed grades.
The PI5C3125 and PI5C3126 are 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 (BE) pin, the 聯(lián)A聰 pin is directly connected to
the 聯(lián)B聰 pin for that particular gate. The bus switch introduces no
additional propagation delay or additional ground bounce noise.
The PI5C3125 device has active LOW enables, and the PI5C3126 has
active HIGH enables.
聲 Packages available:
