PIN NAME

FUNCTION

SSOP24/TSSOP24E/SOP24B: 1

QFN24: 22

GND

Ground terminal.

SSOP24/TSSOP24E/SOP24B: 2

QFN24: 23

DAI

Serial data input terminal.

SSOP24/TSSOP24E/SOP24B: 3

QFN24: 24

CLK

Synchronous clock input terminal for serial data transfer.

Data is sampled at the rising edge of CLK.

SSOP24/TSSOP24E/SOP24B: 4

QFN24: 1

LAT

Input terminal of data strobe.

Data on shift register goes through at the rising edge (edge

trigger). Otherwise, data is latched.

SSOP24/TSSOP24E/SOP24B: 5~20

QFN24: 2~17

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

SSOP24/TSSOP24E/SOP24B: 21

QFN24: 18

EN

Output enable terminal:

‘H’ for all outputs are turned off ,

‘L’ for all outputs are active.

SSOP24/TSSOP24E/SOP24B: 22

QFN24: 19

DAO

Serial data output terminal.

SSOP24/TSSOP24E/SOP24B: 23

QFN24: 20

REXT

External resistors connected between REXT and GND for

output current value setting.

SSOP24/TSSOP24E/SOP24B: 24

QFN24: 21

VCC

Supply voltage terminal.
