PI3CH281

PI3CH281 Low Voltage, High Bandwidth, 2-Channel, 4:1 Mux/DeMux, NanoSwitch™ with Single Enable Features Near-zero propagation delay 5Ω switches connect inputs to outputs High signal passing bandwidth (300MHz) Beyond Rail-to-Rail switching 5V I/O tolerant with 3.3V supply 2.5V and 3.3V supply voltage operation Hot insertion capable Industrial operating temperature: -40ºC to +85ºC 2KV ESD Protection (human body model) Description Pericom Semiconductor’s PI3CH series of switch circuits are produced using the Company’s advanced sub-micron CMOS technology, achieving industry leading performance. The PI3CH281 is a 2-channel, 4:1 Multiplexer/Demultiplexer with 3-state outputs. The switch introduces no additional ground bounce noise or propagation delay. The PI3CH281 device is very useful in switching signals that have high bandwidth (300MHz).
