DESCRIPTION

The A4732 is a Low-Power, Two-Port, High-Speed, USB2.0 (480Mbps) double–pole double-throw (DPDT) Analog Switch featuring an On-Resistance of 6 ohm at VCC=3V and a Low On Capacitance 7pf Typical.

The A4732 is compatible with the requirements of USB2.0 and the wide bandwidth needed to pass the third harmonic, resulting in signals with minimum edge and phase distortion. Superior channel-to channel crosstalk also minimizes interference. Break-before-make function for both parts eliminates signal disruption during switching from preventing both switches being enabled simultaneously.

The A4732 contains special circuitry on the switch I/O pins for applications where the VCC supply is powered-off (VCC=0), which allows the device to withstand an over-voltage condition. This device is designed to minimize current consumption even when the control voltage applied to the Sel pin is lower than the supply voltage (VCC). This feature is especially valuable to ultra-portable applications, such as cell phones, allowing for direct interface with the general purpose I/Os of the baseband processor. Other applications include switching and connector sharing in portable cell phones, PDAs, digital cameras, printers, and notebook computers.

The A4732 is available in TQFN10(1.4x1.8) and MSOP10 packages.
