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.
