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).

Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 3.3V, TA = 25°C ambient and maximum loading.
3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
4. Measured by the voltage drop between A and B pin at indicated current through the switch. On-Resistance is determined by the lower of the
voltages on the two (A,B) pins.
5. This parameter is determined by device characterization but is not production tested.
