功能特点

产品名称:USB/音频模拟开关

产品型号:BCT4321N

产品描述:

The BCT4321N is a double-pole double-throw (DPDT) analog switch with multiplexes USB2.0 and negative signal 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 ?) . 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.
