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 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  
busswitchintroducesnoadditionalpropagationdelayoradditional  
ground bounce noise.  
• 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  
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).  
• Permits Hot Insertion  
• Packaging (Pb-free & Green Available):  
– 8-pin 173-mil wide plastic TSSOP  
– 8-pin 118-mil wide plastic MSOP  
Applications  
• High Bandwidth Data Switching  
• Hot Docking
