TM
3.3V, 10-Bit, 2-Port, NanoSwitch
Features Description
Near-Zero propagation delay Pericom Semiconductors PI3B3861 is a 10-bit, 3.3 volt, 2-port
5-ohm switches connect inputs to outputs bus switch designed with a low On-Resistance (5-ohm) allowing
Fast Switching Speed: 4.5ns (max.) inputs to be connected directly to outputs. The bus switch
Ultra Low Quiescent Power (0.1A typical) creates no additional propagational delay or additional ground
Ideally suited for notebook applications bounce noise. The switches are turned ON by the Bus Enable
Packaging (Pb-free & Green):

Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at V = 3.3V, T = 25C ambient and maximum loading.
CC A
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.
