Product Description
Pericom Semiconductor’s PI3B series of BusSwitch circuits are
produced in the Company’s advanced 0.35 micron CMOS
technology, achieving industry leading speed.
The PI3B16210 is configured as 3.3 volt 20-bit, 2-port bus
switches 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 (xOE) input signal.
The PI3B162210 device has a built-in 25-ohm series resistor to
reduce noise resulting from reflections, thus eliminating the need
for an external terminating resistor.

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.
4. This parameter is determined by device characterization but is not production tested.
