Channel on capacitance: 11pF typ. VCC Operating Range: 3.3V10% >100 MHz Bandwidth Packaging (Pb-free & Green available) : -56-pin 240-mil wide plastic TSSOP(A) Description Pericom Semiconductor's PI3B16234 is a 16-bit to 32-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.
