Pericom Semiconductors PI3C series of logic circuits are produced using the Companys advanced submicron CMOS technology, achieving industry leading speed grades. The PI3C3305 and PI3C3306 are 2.5V or 3.3 Volt, 2-bit bus switches designed 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 PI3C3306 device has active LOW enables, and the PI3C3305 has active HIGH enables. It is very useful in switching signals that have high bandwidth (>400 MHz).

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.
