4-Bit Bus Switch, Enable High 1.8V/2.5V/3.3V,
High-Bandwidth, Hot Plug
Features Description
Near-Zero propagation delay The PI3CH401 is a low voltage, 4-channel switch
5-ohm switches connect inputs to outputs designed with fast individual enables. The switch
High signal passing bandwidth (500 MHz) introduces no additional ground bounce noise or
Beyond Rail-to-Rail switching additional propagation delay.
- 0 to 5V switching with 3.3V power supply The PI3CH401 device has active low enables. It is
- 0 to 3.3V switching with 2.5V power supply very useful in switching signals that have high
5V I/O tolerant with supply in OFF and ON state bandwidth (500 MHz).
1.8V, 2.5V and 3.3V supply voltage operation
