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 PI5C3301 is a single 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 PI5C3301 device has an active LOW enable.
