Description
Pericom Semiconductor’s PI3C32X245 is a 2.5V or 3.3V 16-bit, 2-port
bus switch designed with a low On-Resistance (5-ohm) allowing
inputs to be connected directly to outputs. The bus switch creates
no additional propagational delay or additional ground bounce
noise. The switches are turned ON by the Bus Enable (BEN) input
signal. It is very useful in switching signals that have high bandwidth
(>400MHz).

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.
