PI5C3305

Features Near-Zero propagation delay 5Ω switches connect inputs to outputs Direct bus connection when switches are ON Ultra Low Quiescent Power (0.2μA typical) – Ideally suited for notebook applications Packaging (Pb-free & Green available): – 8-pin 173-mil wide plastic TSSOP (L) – 8-pin 118-mil wide plastic MSOP (U) PI5C3305 2-Bit Bus Switch with Individual Enables Description Pericom Semiconductor’s PI5C3305 is a 2-bit bus switch designed with two individual 5Ω switches with fast individual enables. When enabled via the associated Bus Enable (BE) pin, the “A” pin is directly connected to the “B” pin for that particular gate. The bus switch introduces no additional propagation delay or additional ground bounce noise. The PI5C3305 device has active HIGH enables.
