PI3C3305

PI3C3305 PI3C3306 2.5V/3.3V, High Bandwidth, Hot Insertion, 2-Bit, 2-Port Bus Switch w/ Individual Enables Features 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 (Pb-free & Green Available): – 8-pin 173-mil wide plastic TSSOP – 8-pin 118-mil wide plastic MSOP Description Pericom Semiconductor’s 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).
