PI5C3305 2-Bit Bus Switch with Individual Enables Features Description • Near-Zero propagation delay Pericom Semiconductor’s PI5C3305 is a 2-bit bus switch designed • 5Ω switches connect inputs to outputs with two individual 5Ω switches with fast individual enables. When 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 (0.2μA 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 Confi guration A1 B1 BE 1 8 V BE1 1 CC A 2 7 BE 1 2 B 3 6 B A2 B2 1 2 GND 4 5 A 2 BE2 Pin Description Truth Table(1) Pin Name Description BE A B V Function n n n CC BEn Switch Enable X(2) Hi-Z Hi-Z GND Disconnect A2-A1 Bus A L Hi-Z Hi-Z VCC Disconnect B2-B1 Bus B H Bn An VCC Connect VCC Power Notes: 1.

See test circuit and waveforms. 2. This parameter is guaranteed but not tested on Propagation Delays. 3. The bus switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.25ns for 50pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side. 09-0007 3 PS8331I 12/02/09
