PI5C3306
2-Bit Bus Switch with
Active Low Enables
Features Description
Near zero propagation delay e PTh I5C3306 is a 2-bit bus switch designed with two 5-ohm
bus switches with fast individual enables. When enabled via
5-ohm switches connect inputs to outputs
the associated Bus Enable (BE) pin, the A pin is directly con-
Direct bus connection when switches are ON
nected to the B pin for that particular gate. The bus switch in-
Ultra Low Quiescent Power (0.2A typical)
troduces no additional propagation delay or additional ground
Ideally suited for notebook applications
bounce noise. The PI5C3306 device has active LOW enables.
Packages available (Pb-free and Green available):
8-pin, 173-mil wide plastic TSSOP (L)
