Pericom Semiconductor’s PI5C series of logic circuits are produced using the Company’s advanced submicron CMOS technology, achieving industry leading speed grades. The PI5C3301 is a single digital switch designed with a fast enable. When enabled via the associated Bus Enable (BE) pin, the “A” pin is directly connected to the “B” pin. The bus switch introduces no additional propagation delay or additional ground bounce noise. The PI5C3301 device has an active LOW enable. Product Features
- Near zero propagation delay
- 5-Ohm switches connect inputs to outputs
- Direct bus connection when switches are ON
- Ultra Low Quiescent Power (0.2µA Typical) – Ideally suited for notebook applications

Typical values are at V CC = 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 determine 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.

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.
