LATCH
GND terminal for control logic
Input terminal for serial data for data shift register
Input terminal for clock for data shift on rising edge
Input terminal for data strobe
When the LATCH input is driven High, data is not latched. When it is pulled Low, data is
latched.
Function
OUT0 to OUT15 Constant-current output terminals
Input terminal for output enable.
All outputs ( OUT0 to OUT15 ) are turned off, when the ENABLE terminal is driven High.
And are turned on, when the terminal is driven Low.
Output terminal for serial data input on SERIAL-IN terminal
Input terminal used to connect an external resistor. This regulated the output current.
