A4732
DPDT ANALOG SWITCH
LOW-POWER, TWO-PORT, HIGH-SPEED, USB2.0 (480Mbps)
DESCRIPTION
FEATURES
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
4.5 ohm at VCC=3V and a Low On Capacitance 3.7pf
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(1.8x1.4) and
MSOP10 packages.
