The PI3B16292 is a 3.3 volt, 12-bit to 24-bit Mux/Demux Bus switches designed with a low On-resistance allowing inputs to be connected directly to outputs. A2 port is not externally connected and, as a result, has an internal 500 ohm pulldown resistor to ground. • • • • Near-zero propagation delay 5 ohm switches connect inputs to outputs Fast Switching Speed - 5ns (max.) Internal 500 ohm pull-down on A2 ports Ultra-low quiescent power (0.2µA typical) – Ideally suited for notebook applications Vcc Operating Range : 3.0V to 3.6V Industrial operating temperature: –40°C to +85°C Make-before-break switching Packages available: – 56-pin 240-mil wide thin plastic TSSOP (A) – 56-pin 300-mil wide plastic SSOP (V) Pin Configuration Applications S0 • Memory switching 1 A1 Logic Block Diagram 2 A1 NC NC ONE OF TWELVE CHANNELS 1A1 3 A1 NC 1B1 SW 1 2 56 55 NC NC 3 4 54 53 1 B2 5 6 52 51 2 B2 7 8 50 49 GND 48 47 3 B2 46 45 44 4 B2 SW GND 4 A1 SW NC 5 A1 9 10 11 NC 12 6 A1 7 A1 13 14 15 NC 16 VCC 8 A1 17 18 19 1B2 SW 500Ω NC FLOW CONTROL SW S0 GND A NC B 9 A1 NC 10A1 So NC 11A1 NC Product Pin Description 12A1 Pin Name I/O De s cription S0 I xA1 I/O Bus A xBx I/O Bus B NC 20 21 22 23 24 25 26 27 28 56-Pin A, V 1 B1 2 B1 3B1 4B1 5B1 5 B2 43 6B1 42 41 40 6 B2 39 38 37 36 35 34 33 8 B1 7B1 7 B2 GND 8 B2 9B1 9 B2 10B1 10B2 32 11B1 31 30 29 11B2 12B1 12B2 Select Inputs Truth Table NC Leave it unconnected Function S0 A1 A2 NC1 Leave it unconnected A1 to B1, A2 to B2 L B1 B2 A1 to B2, A2 to B1 H B2 B1 Note: 1.

This is the increase in supply current for S0 at the specified TTL voltage level rather than VCC or GND. 4. Per driven input ( S0 only); A and B pins do not contribute to ICC. 5. This current applies to the control inputs only and represent the current required to switch internal capacitance at the specified frequency. The A and B inputs generate no significant AC or DC currents as they transition. This parameter is not tested, but is guaranteed by design. Switching Characteristics over Operating Range Com.

The bus switch contributes no propagational delay other than the RC delay of the ON resistance of the switch and load capacitance. The time constant for the switch alone is of the order of 0.25ns for 50pF load. Since this time constant is much smaller than 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. 4.
