Description:
The BROADCHIP BCT4321NETB-TR is a versatile DPDT analog switch capable of handling USB2.0 Hi-Speed data and negative signal audio analog signals. It offers a wide -3dB bandwidth of 720MHz in USB mode, ensuring good signal integrity for high-speed differential signals. The switch also features ultra-low on-resistance, measuring 2.5 ohms at 3.6V in Audio Mode and 8.5 ohms at 3.6V in USB Mode.

With an operating voltage range of 2.7V to 5.0V, the BCT4321NETB-TR provides flexibility in design. It boasts excellent channel-to-channel crosstalk rejection of 86dB at 1MHz and off-isolation of 66dB at 1MHz, minimizing noise interference. The device includes audio channel shunt resistors for pop and click noise reduction and power-off protection on common D+/R and D-/L ports.

This analog switch is available in a compact QFN1.4X1.8-10 package, making it suitable for space-constrained applications. It operates within an ambient temperature range of -40°C to +85°C. Applications include cell phones, Hi-Fi audio switching, and USB 2.0 high-speed data switching.
