Function

P-channel MOSFET drain; Channel 4 output pin.

P-channel MOSFET drain; Channel 5 output pin.

P-channel MOSFET drain; Channel 6 output pin.

P-channel MOSFET drain; Channel 7 output pin.

Ground connection.

Input control pin using AS2Cwire serial interface. The device records rising edges of the clock, and

decodes them into 128 states controlling the ON/OFF states of the outputs. See Table 1 and Table 2 for

output settings. In addition, a logic low forces the device into shutdown mode, reducing the supply cur-

rent to less than 1μA. This pin should not be left floating.

P-channel MOSFET drain; Channel 1 output pin.

P-channel MOSFET drain, Channel 2 output pin.

P-channel MOSFET drain, Channel 3 output pin.

Input supply voltage. VIN is connected to the P-channel MOSFET common sources. Connect a 1μF ce-

ramic capacitor from VIN to GND.
