Pulldown on B Ports Low Power: 1mW Industrial Operation Temperature: –40ºC to 85ºC Near-Zero Propagation Delay Switching Speed: 4.5ns (max.) Channel on capacitance: 11pF (typ.) VCC Operating Range: 3.3V±10% >100 MHz bandwidth Packaging : – 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® 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.
