Channel on capacitance: 11pF typ. VCC Operating Range: 3.3V10% >100 MHz bandwidth Packaging (Pb-free & Green available): -40-pin BQSOP (B) Description Pericom Semiconductor's PI3B16226 is a 12-bit to 24-bit mux/demux switch. Industry leading advantages include almost zero propagation delay of 500ps because of 8-ohm channel resistance and low I/O capacitance. A1 port demultiplexes to either port B1 or B2. The switch is bidirectional.

For example, given a + 3.3V supply, IN may be driven low to 0V and high to 3.6V. Driving IN Rail-to-Rail(R) 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. Rail-to-Rail is a registeredtrademark of Nippon Motorola, Ltd.
