PI3B3861 3.3V, 10-Bit, 2-Port, NanoSwitchTM Features Description ÎÎNear-Zero propagation delay Pericom Semiconductor’s PI3B3861 is a 10-bit, 3.3 volt, 2-port ÎÎ5-ohm switches connect inputs to outputs bus switch designed with a low On-Resistance (5-ohm) allowing ÎÎFast Switching Speed: 4.5ns (max.) inputs to be connected directly to outputs. The bus switch ÎÎUltra Low Quiescent Power (0.1μA typical) creates no additional propagational delay or additional ground bounce noise. The switches are turned ON by the Bus Enable àà Ideally suited for notebook applications ÎÎPackaging (Pb-free & Green): (BE) input signal. àà 24-pin 150-mil wide plastic QSOP (Q) Block Diagram Pin Configuration A0 SW B0 A9 SW B9 NC A0 A1 A2 A3 A4 A5 A6 A7 A8 A9 GND SW BE A B 1 2 3 4 5 6 7 8 9 10 11 12 24 23 22 21 20 19 18 17 16 15 14 13 Vcc BE B0 B1 B2 B3 B4 B5 B6 B7 B8 B9 BE Truth Table(1) Pin Description Function BE A0–9 Pin Name Description Disconnect H Hi-Z BE Connect L B0–9 A0-9 Bus A Bus Enable Input (Active LOW) Note: H = High Voltage Level B0-9 Bus B L = Low Voltage Level Hi-Z = High Impedance GND Ground All trademarks are property of their respective owners.

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.

See test circuit and wave forms. 2. This parameter is guaranteed but not tested on Propagation Delays. 3. The bus switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.25 ns for 50 pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side. Applications Information Logic Inputs The logic control inputs can be driven up to +3.6V regardless of the supply voltage. For example, given a + 3.3V supply, IN may be driven low to 0V and high to 3.6V. Driving IN Rail-to-Rail® minimizes power consumption. Power-Supply Sequencing and Hot-Plug Information Proper power-supply sequencing is recommended for all CMOS devices. Always apply VCC and GND before applying signals to input/output or control pins.
