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).

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

Applications

• High Bandwidth Data Switching

• Hot Docking
