PI3C3305 PI3C3306 2.5V/3.3V, High-Bandwidth, Hot-Insertion, 2-Bit, 2-Port Bus Switch w/ Individual Enables Features Description Near-Zero propagation delay Pericom Semiconductors PI3C3305 and PI3C3306 are 2.5 volt or 3.3 volt, 2-bit bus switches designed with fast individual enables. 5 switches connect inputs to outputs When enabled via the associated Bus Enable (BE) pin, the A pin High Bandwidth (>400 MHz) is directly connected to the B pin for that particular gate. The Rail-to-Rail, 3.3V or 2.5V Switching bus switch introduces no additional propagation delay or additional 5V I/O Tolerant ground bounce noise. 2.5V Supply Voltage Operation The PI3C3306 device has active LOW enables, and the PI3C3305 Permits Hot Insertion has active HIGH enables. It is very useful in switching signals that have high bandwidth (>400 MHz).
