PIN NAME
FUNCTION
1
GND
GND terminal for control logic.
2
SERIAL- IN
Input terminal of a serial- data for shift- register.
3
CLOCK
Input terminal of a clock for data shift to up- edge.
4
LATCH
Input terminal of a data strobe. Latches passes data with “H” level input of
LATCH
- terminal, and hold data with "L" level input.
5~20
15
~
OUT0
Output terminals.
21
ENABLE
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.
22
SERIAL- OUT
Output terminal of a serial- data for next SERIAL- IN terminal.
23
R- EXT
Input terminal of connects with a resister for to set up all output current.
24
V
DD
5 V Supply voltage terminal.
