PI3C3305UEX

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 • 5Ω switches connect inputs to outputs • High Bandwidth (>400 MHz) • Rail-to-Rail, 3.3V or 2.5V Switching • 5V I/O Tolerant • 2.5V Supply Voltage Operation • Permits Hot Insertion • Packaging: – 8-pin 173-mil wide plastic TSSOP – 8-pin 118-mil wide plastic MSOP PI3C3305 and PI3C3306 are 2.5 volt 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).

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.
