Pin Name

Function

GND

GND terminal for control logic.

SERIAL-IN Input terminal for serial data for data shift register.

CLOCK

Input terminal for clock for data shift on rising edge.

LATCH

Input terminal for data strobe.

When the LATCH input is driven High, data is latched. When it is pulled Low, data is hold.

OUT0 ~ OUT7 Constant-current output terminals.

Input terminal for output enable.

ENABLE All outputs ( OUT0 ~ OUT7 ) are turned off, when the ENABLE terminal is driven High.

And are turned on, when the terminal is driven Low.

SERIAL-OUT Output terminal for serial data input on SERIAL-IN terminal.

R-EXT

Input terminal used to connect an external resistor. This regulated the output current.

VDD

3.3-V supply voltage terminal.
