PI3C3384
2.5V/3.3V, High Bandwidth, Hot Insertion
10-Bit, 2-Port, Bus Switch
Description
Pericom Semiconductor’s PI3C3384 is a 2.5V or 3.3V, high
bandwidth 10-bit, 2-port bus switches designed with a low On-
Resistance 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 (BE) input signal. Two bus enable signals are
provided, one for each of the upper and lower five bits of the
two 10-bit buses.
Applications
• High Bandwidth Data switching
• Hot Docking

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 volt-
ages on the two (A,B) pins.
4. This parameter is determined by device characterization but is not production tested.
