1 PI , Synchronous 6-it to 3-it FET Mux/DeMux NanoSwitch Features Near-Zero propagation delay. Ω Switches Connect etween Two Ports Packaging: - -pin 40mil Wide Thin Plastic TSSOP (A) - -pin 300mil Wide Plastic SSOP () lock Diagram Description Pericom Semiconductor s PI3 series of logic circuits are produced using the company's advanced submicron CMOS technology. The PI363 is a 3.3 volt, 6-bit switch. Pin Configuration to 3-bit synchronous Two select inputs (S0 and S) control the data flow. A clock () and a clock enable (EN) synchronize the device operation. When EN is high, the bus switch remains in the last clocked function. 8 EN 7 S0 30 D CE S 9 D CE of 6 Channels A A S Truth Table S S0 EN Function X X X H Last State L L L Disconnect L H L A = and A = H L L A = H H L A = A 3A 4 4 A A 8 8 GND c c 9A 0 0 A 3A 4 4 A 6 6 EN Pin A, A 3 3 4A 6A 7 7 8A GND cc 9 9 0A A 3 3 4A 6A S0 S

5 PI , Synchronous 6-it to 3-it Applications Information Logic Inputs The logic control inputs can be driven up to +3.6 regardless of the supply voltage. For example, given a supply, IN may be driven low to 0 and high to 3.6. 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 CC and GND before applying signals to input/output or control pins.
