PI5C16212 24-Bit Bus Exchange Switch Features Description Pericom Semiconductors PI5C16212 is a 24-bit bus exchange Near-Zero propagation delay switch designed with Low On-Resistance allowing inputs to be 5-ohm switches connect inputs to outputs connected directly to outputs. This device operates as a 24-bit Direct bus connection when switches are ON bus switch or a 12-bit exchanger that provides data exchanging Ultra-low quiescent power (0.1A typical) between the four signal ports via the data select pins (S0-S2). Ideally suited for notebook applications Industrial operating temperature: 40C to +85C Packaging (Pb-free & Green Available): 56-pin 240-mil wide thin plastic TSSOP (A) Logic Block Diagram Pin Con guration S0 1 56 S1 ONE OF TWELVE CHANNELS 11A S2 2 55 11A 11B 12A 3 54 11B 21A 4 53 12B 22A 21B 5 52 31A 6 22B 51 32A 31B 7 50 12B 12A GND GND 8 49 41A 32B 9 48 42A 10 47 41B FLOW CONTROL 51A 11 46 42B 52A 51B 12 45 S0 61A 13 52B 44 S1 62A 61B 14 43 62B 71A 15 42 S2 72A 71B 16 41 17 40 72B VCC 81A (1) 18 39 81B Truth Table GND GND 19 38 Function S2 S1 S0 A1 A2 82A 20 82B 37 91A 21 36 91B Disconnect L L L Z Z 92A 22 35 92B A1 to B1 L L H B1 Z 10A1 23 34 10B1 A1 to B2 L H L B2 Z 24 33 10A2 10B2 11A1 25 32 11B1 A2 to B1 L H H Z B1 11A2 26 31 11B2 A2 to B2 H L L Z B2 27 30 12A1 12B1 12A2 28 29 12B2 Disconnect H L H Z Z A1 to B1, A2 to B2 H H L B1 B2 Pin Description A1 to B2, A2 to B1 H H H B2 B1 Pin Name I/O Description Note: S0 - S2 I Select Inputs 1.
