Terminal description

Pin No.

Pin Name

Function

1

GND

GND terminal for control logic

2

SERIAL-IN

Input terminal for serial data for data shift register

3

CLOCK

Input terminal for clock for data shift on rising edge

4

LATCH

Input terminal for data strobe When the LATCH=High-level, data is no latched. When

ithe LATCH=Low-level, data is latched.

5 ~ 20

OUT 0 ~ 15

Constant-current output terminals

21

ENABLE

Input terminal for output enable.

All outputs (OUT0 ~ OUT15 ) are turned off, when the ENABLE=High-level.

And are turned on, when the ENABLE=Low-level.

22

SERIAL-OUT Output terminal for serial data input on SERIAL-IN terminal

23

R-EXT

Input terminal used to connect an external resistor.

This regulated the output current.

24

VDD

3.3V - 5V supply voltage terminal.
