Function
Input supply voltage.
Channel 2 output pin.
Channel 1 output pin.
Input control pin using S²Cwire serial interface. The device records rising edges
of the clock and decodes them into 32 (AAT4296) or 64 (AAT4298) states con-
trolling the ON/OFF states of the outputs. See Table 1 for output settings. In
addition, a logic low forces the device into shutdown mode, reducing the supply
current to less than 1µA. This pin should not be left floating.
Ground.
Channel 5 output pin.
Channel 4 output pin.
Channel 3 output pin.
Channel 6 output pin.
Not connected.
