AOZ6184QT

Overview

The AOZ6184QT is a high-speed Double-Pole, Double-Throw (DPDT) switch designed for USB 2.0 applications operating at data rates up to 480 Mbps. It functions as a low-voltage signal routing component with an ultra-low on resistance of 8 ohms typical and on capacitance of 3.6 pF typical. The device operates from a single supply voltage ranging from 1.65 V to 4.5 V. Key electrical characteristics include a wide -3 dB bandwidth of 1.1 GHz, guaranteed Break-Before-Make switching to prevent driver shorting, and over-voltage tolerance on all data ports up to 5.5 V. It is housed in a QFN-10 package measuring 1.8 mm x 1.4 mm x 0.55 mm.

Procurement Notes

Verify the specific ordering suffix QT against official Alpha & Omega Semiconductor documentation to confirm the QFN-10 package type and the specified -40 °C to +85 °C ambient temperature operating range. Ensure that the procurement channel provides original manufacturer packaging or verified equivalents to maintain component integrity.

Selection Notes

Select this component when designing circuits requiring signal switching between two USB 2.0 sources. Consider its low on capacitance and wide bandwidth for maintaining signal integrity at high frequencies. Verify that the system supply voltage falls within the 1.65 V to 4.5 V range and that the application requires over-voltage protection on the data lines.
