Pin Configuration
The PI3CH3244 is a Low-voltage, 8-channel switch
designed with fast enables. The switch creates no
additional ground bounce noise or propagation delay.
The PI3CH3244 device has two active LOW
enables. It is very useful in switching signals that have
high bandwidth (500 MHz).
Applications
High Bandwidth Data Switching
Hot-Docking
Analog Signal Switching

Note:
Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the
device. This is a stress rating only and functional
operation of the device at these or any other condi-
tions above those indicated in the operational sec-
tions of this specification is not implied. Exposure
to absolute maximum rating conditions for extended
periods may affect reliability.

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. 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.
