FUNCTION
GND terminal for control logic.
Input terminal of a serial−data for shift−register.
Input terminal of a clock for data shift to up−edge.
Input terminal of a data strobe. Latches passes data with “H” level input of
LATCH −terminal, and hold data with "L" level input.
Output terminals.
Input terminal of output enable. All outputs (OUT0~15) do off with “H” level input of
ENABLE −terminal, and do on with "L" level input.
Output terminal of a serial−data for next SERIAL−IN terminal.
Input terminal of connects with a resister for to set up all output current.
5 V Supply voltage terminal.

A resistor is connected with R−EXT and GND accompanied with outside, and it is necessary that a correct
power supply voltage is supplied.
