PI5C3306
2-Bit Bus Switch with
Active Low Enables
Description
The PI5C3306 is a 2-bit bus switch designed with two 5-ohm
bus switches with fast individual enables. When enabled via
the associated Bus Enable (BE) pin, the “A” pin is directly con-
nected to the “B” pin for that particular gate. The bus switch in-
troduces no additional propagation delay or additional ground
bounce noise. The PI5C3306 device has active LOW enables.
