PI3USB20 3.3V, Wide Bandwidth, 4-Channel, 2:1 Mux/DeMux USB 2.0 Switch w/ Single Enable Features Description R is 4 typical The PI3USB20 is a 8- to 4-Channel multiplexer/demultiplexer Video ON Switch with Hi-Z outputs. Industry leading advantages include a Low bit-to-bit skew: 200ps propagation delay of less than 250ps, resulting from its low channel Low Crosstalk: 27dB 250MHz resistance and I/O capacitance. Near-Zero propagation delay: 250ps The device multiplexes differential outputs from a USB Host device Switching speed: 9ns to one of two corresponding outputs. The switch is bidirectional and offers little or no attenuation of the high-speed signals at the Channel On-Capacitance: 6pF (typical) outputs. It is designed for low bit-to-bit skew, high channel-to- V Operating Range: +3.0V to +3.6V CC channel noise isolation and is compatible with various standards, ESD>2000V .
