BCT4221

December, 2013, REV1.1 BCT4221 High-Speed & Low-Ron DPDT Analog Switch General Description The BCT4221 double-pole double-throw (DPDT) analog switch multiplexes Hi-speed (480MHz) USB and audio analog signals. One Channel has wide bandwidth and low bit-to-bit skew allow it to pass high-speed differential signals with good signal integrity. Another channel has ultra Low on resistance (1.0 Ω) . Each switch is bidirectional and offers little or no attenuation of the signals at the outputs. Industry-leading advantages include a propagation delay of less than 250ps, resulting from its low channel resistance and low I/O capacitance. Their high channel-to-channel crosstalk rejection results in minimal noise interference. Features ♦ VCC Operating Range: 1.65V to 5.0V ♦ Low ON Resistance: 1.0-ohms at 5.0V (Audio Mode) ♦ Rail-to-Rail Signal Range ♦ ON-Resistance Matching: 0.2 Ω (Audio Mode) ♦ ON-Resistance Flatness: 0.1Ω (Audio Mode) ♦ High Off Isolation: 57dB at 10MHz ♦ 54...
