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 latched. When it is pulled Low, data is hold.
Constant­current output terminals.
Input terminal for output enable.
All outputs ( OUT0 to OUT7 ) be 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 SERIAL­IN terminal.
Input terminal used to connect an external resistor. This regulated the output current.
3.3­V and 5­V supply voltage terminal.
