PIN NAME

FUNCTION

DIP24/SOP24/SSOP24/TSSOP24: 1

TSSOP24: exposed pad

QFN32: 1, 2, 5, 6, 7, 8, 12, 29,

exposed pad

GND

Ground terminal.

DIP24/SOP24/SSOP24/TSSOP24: 2

QFN32: 9

DAI

Serial data input terminal.

DIP24/SOP24/SSOP24/TSSOP24: 3

QFN32: 10

DCK

Synchronous clock input terminal for serial data transfer. Data

is sampled at the rising edge of DCK.

DIP24/SOP24/SSOP24/TSSOP24: 4

QFN32: 11

LAT

Input terminal of data strobe. Data on shift register goes

through at the rising edge of LAT (edge trigger). Otherwise,

data is latched.

DIP24/SOP24/SSOP24/TSSOP24: 5~20

QFN32: 13~28

OUT0~15 Sink constant-current outputs (open-drain).

DIP24/SOP24/SSOP24/TSSOP24: 21

QFN32: 30

EN

Output enable terminal:

‘H’ for all outputs are turned off ,

‘L’ for all outputs are active.

DIP24/SOP24/SSOP24/TSSOP24: 22

QFN32: 31

DAO

Serial data output terminal.

DIP24/SOP24/SSOP24/TSSOP24: 23

QFN32: 32

REXT

External resistors connected between REXT and GND for

output current value setting.
