功能特点

BCT4221 双通道高速720Mhz/低阻1.0欧 USB/音频模拟开关

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.
