功能特点

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.
