产品名称:双刀双掷模拟开关
产品型号:BCT4222B
产品描述:
The BCT4321 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 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.
