AOZ6184 High-Speed USB 2.0 (480 Mbps) DPDT Switch General Description Features The AOZ6184 is a low-voltage high-speed Double-Pole, Double-Throw (DPDT) switch for switching between two USB 2.0 (480 Mbps) sources. The device features very low on capacitance (3.6 pF typ.) and is designed to operate from a single 1.65 V to 4.5 V supply. The AOZ6184 features an ultra-low on resistance (8 Ω typ.), and low power consumption. The device also features fast switching and guaranteed Break-BeforeMake (BBM) switching, assuring the switches never short the driver. z Low On Resistance (RON) for 3.6 V supply (8 Ω) z Low On Capacitance (CON) for 3.6 V supply (3.6 pF) z Over-voltage tolerance (OVT) on all data ports up to 5.5 V z QFN-10: 1.8 mm x 1.4 mm x 0.55 mm z Broad 1.65 V to 4.50 V VCC operating range z Wide –3 dB bandwidth: 1.1 GHz typ.
