PI5C3305 2-Bit Bus Switch with Individual Enables Features Description Near-Zero propagation delay Pericom Semiconductors PI5C3305 is a 2-bit bus switch designed with two individual 5 switches with fast individual enables. When 5 switches connect inputs to outputs enabled via the associated Bus Enable (BE) pin, the A pin is Direct bus connection when switches are ON directly connected to the B pin for that particular gate. The bus Ultra Low Quiescent Power (0.2A typical) switch introduces no additional propagation delay or additional Ideally suited for notebook applications ground bounce noise. Packaging (Pb-free & Green available): The PI5C3305 device has active HIGH enables. 8-pin 173-mil wide plastic TSSOP (L) 8-pin 118-mil wide plastic MSOP (U) Block Diagram Pin Con guration B A 1 1 BE 1 8 V BE 1 CC 1 A 2 7 BE 1 2 B 3 6 B 1 2 A B 2 2 GND 4 5 A 2 BE 2 (1) Pin Description Truth Table Pin Name Description BE A B V Function n n n CC (2) BE Switch Enable X Hi-Z Hi-Z GND Disconnect n A -A Bus A L Hi-Z Hi-Z V Disconnect 2 1 CC B -B Bus B HB A V Connect 2 1 n n CC V Power Notes: CC 1.
