Pin Description

QFN TSSOP

1 22 SERIAL-OUT

Output terminal for serial data input on SERIAL-IN

terminal.

2 23 R-EXT

Input terminal used to connect an external resistor.

This regulated the output current.

3 24 VDD Supply voltage terminal.

4 1 GND GND terminal for control logic.

5 2 SERIAL-IN Input terminal for serial data for data shift register.

6 3 CLOCK Input terminal for clock for data shift on rising edge.

7 4

LATCH

————————

Input terminal for data strobe When the L A T C H

————————

input is driven High, data is not latched. When it is

pulled Low ，data is latched.

8 ~ 23 5~20

OUT0

~OUT15

———————

Constant-current output terminals.

24 21

ENABLE

—————————

Input terminal for output enable.

All outputs (OUT0

——————

to OUT15

———————

) are turned off, when

the ENABLE

—————————

terminal is driven High .And are turned

on, when the terminal is driven Low.

Thermal Pad Connect to GND.

Warning:

Latch circuit is leveled-latch circuit. Be careful because it is not triggered-latch circuit.

Note : The latches circuit holds data by pulling the L A T C H

————————

terminal Low. And, when L A T C H

————————

terminal is a High level, latch circuit

doesn’t hold data, and it passes from the input to the output. When E N A B L E

—————————

terminal is a Low level, output terminal O U T 0

——————

to O U T 1 5

———————

respond to the data, and on and off does. And, when E N A B L E

—————————

terminal is a High level, it offs with the output terminal regardless of the

data.
