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 PI5C3308 is a 2-bit digital switch designed with a fast enable.
When enabled via the associated Bus Enable (BE) pin, the “A” pin
is directly connected to the “B” pin. The bus switch introduces no
additional propagation delay or additional ground bounce noise.
The PI5C3308 device has an active LOW enable.
