Logic Block Diagram
Product Description
Pericom’s Semiconductor’s PI3C series of logic circuits are
produced using the Company’s advanced submicron CMOS
technology, achieving industry leading performance.
The PI3C3861 is a 10-bit, 2.5V or 3.3 volt, 2-port bus switch
designed with a low ON-Resistance (5) 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. This device is very userful 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.
