3.3V, 10-Bit, 2-Port, NanoSwitch
Features
• Near-Zero propagation delay
• 5-ohm switches connect inputs to outputs
• Fast Switching Speed - 4.5ns (max.)
• Ultra Low Quiescent Power (0.1µA Typical)
– Ideally suited for notebook applications
• Packaging (Pb-free & Green available):
– 24-pin 150-mil wide plastic QSOP (Q)
– 24-pin 173-mil wide plastic TSSOP (L)
Description
Pericom’s Semiconductor’s PI3B3861 is a 10-bit, 3.3 volt, 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
(BE) input signal.

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.
