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