PI5C3303 SOTiny™ 2:1 Mux/DeMux Bus Switch Features Description • Near-Zero propagation delay Pericom Semiconductor’s PI5C3303 is a single 2:1 Mux/DeMux digital switch designed with a fast enable. When enabled using the Bus Enable (BE) pin, the “A” or “B” pin is directly connected to the “C” pin. The bus switch introduces no additional propagation delay or additional ground bounce noise. • 5Ω switches connect inputs to outputs • Direct bus connection when switches are ON • Ultra Low Quiescent Power (0.1µA Typical) – Ideally suited for notebook applications The PI5C3303 device has an active HIGH enable. • Packaging (Pb-free & Green available): – 6-pin plastic S0T-23 (T) Block Diagram Pin Configuration A C BE �� � � � ��� � � � ��� � � � B Truth Table(1) Pin Description BE A B C Function L C X A Connect A & C BE Switch Enable H X C B Connect B & C A Bus A at pin 6 B Bus B at pin 4 C Bus C at pin 5 VCC Power GND Ground Pin Name Notes: 1.

For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type. 2. Typical values are at VCC = 5.0V, TA = 25°C ambient and maximum loading. 3. Measured by the voltage drop between A and B pin at indicated current through the switch. On-Resistance is determined by the lower of the voltages on the two (A, B) pins. 4. This parameter is determined by device characterization but is not production tested. 2 PS8367D 10/14/04 PI5C3303 SOTiny™ 2:1 Mux/DeMux Bus Switch Power Supply Characteristics Test Conditions(1) Parameters Description Min.

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 his 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. 3.
