Product Description

Pericom Semiconductor’s PI5C series of logic circuits are produced

using the Company’s advanced submicron CMOS technology,

achieving industry leading speed grades.

The PI5C3305 is a 2-bit bus switch designed with two individual

5-ohm bus switches with fast indiviual enables. 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 PI5C3305 device has active HIGH enables.
