PI3B16232 3.3V, Synchronous 16-Bit to 32-Bit FET Mux/DeMux NanoSwitch™ Features Description • Near-Zero propagation delay. The PI3B16232 is a 3.3 volt, 16-bit switch. • 5-ohm Switches Connect Between Two Ports to 32-bit synchronous • Packaging (Pb-free & Green available): – 56-pin 240mil Wide Thin Plastic TSSOP (A) Two select inputs (S0 and S1) control the data flow. A clock (CLK) and a clock enable (CLKEN) synchronize the device operation. When CLKEN is high, the bus switch remains in the last clocked function.

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.
