FUNCTION

1

GND

Ground terminal.

2

DAI

Serial data input terminal.

3

DCK

Synchronous clock input terminal for serial data transfer. Data is sampled at the rising

edge of DCK.

4

LAT

Input terminal of data strobe. Data on shift register goes through at the high level of LAT

(level trigger). Otherwise, data is latched.

5-20

OUT0-15

Sink constant-current outputs (open-drain).

21

EN

Output enable terminal:

‘H’ for all outputs are turned off,

‘L’ for all outputs are active.

22

DAO

Serial data output terminal.

23

REXT

External resistors connected between REXT and GND for output current value setting.

24

Supply voltage terminal.
