PIN NAME

FUNCTION

SOP24/SOP24B/SSOP24/TSSOP24E: 1

TSSOP24E, QFN32: exposed pad

QFN32: 1, 2, 5, 6, 7, 8, 20,21

GND

Ground terminal.

SOP24/SOP24B/SSOP24/TSSOP24E: 2

QFN32: 9

DAI

Serial data input terminal.

SOP24/SOP24B/SSOP24/TSSOP24E: 3

QFN32: 10

DCK

Synchronous clock input terminal for serial data transfer.

Data is sampled at the rising edge of DCK.

SOP24/SOP24B/SSOP24/TSSOP24E: 4

QFN32: 11

LAT

Input terminal of data strobe:

‘H’ means data on shift register goes through latch

(level trigger),

‘L’ means data is latched.

SOP24/SOP24B/SSOP24/TSSOP24E:

5~20

QFN32: 12~19, 22~29

OUT0~15

Sink constant-current outputs (open-drain).

SOP24/SOP24B/SSOP24/TSSOP24E: 21

QFN32: 30

SOMODE

/GCK

Serial Out Mode Selection(SOMODE) :

‘H’: DAO is shifted out and synchronized to

falling edge of DCK,

‘L’ : DAO is shifted out and synchronized to

rising edge of DCK.

Gray Scale Clock(GCK) : Input terminal for PWM operation.

SOP24/SOP24B/SSOP24/TSSOP24E: 22

QFN32: 31

DAO

Serial data output terminal.

SOP24/SOP24B/SSOP24/TSSOP24E: 23

QFN32: 32

REXT

External resistors connected between REXT and GND for

output current value setting.

SOP24/SOP24B/SSOP24/TSSOP24E: 24

QFN32: 3, 4

VCC

Supply voltage terminal.
