Product Description
Pericom Semiconductor鈥檚 PI5C series of logic circuits are produced
using the Company鈥檚 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 鈥淎鈥?pin
is directly connected to the 鈥淏鈥?pin. The bus switch introduces no
additional propagation delay or additional ground bounce noise.
The PI5C3301 device has an active LOW enable.
