USB Switch/Audio Switch
GT4321
The GT4321 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 (2.5Ω). 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.The GT4321 is available in Green QFN1.4*1.8-10 packages. It operates over an ambient temperature range of -40°C to +125°C.
