DESCRIPTION

1

GND

Ground terminal for control logic and current sink

2

SERIAL-IN

Serial-data input to the shift register

3

CLOCK

Clock input terminal for data shift on rising edge

4

LATCH

Data strobe input terminal

Serial data is transferred to the output latch when LE is high. The data is latched when

LE goes low.

5~20

OUT0~15

Constant current output terminals

21

ENABLE

Output enable terminal

When (active) low, the output drivers are enabled; when high, all output drivers are

turned OFF (blanked).

22

SERIAL-OUT

Serial-data output to the following SDI of next driver IC

23

Input terminal used to connect an external resistor for setting up output current for all

output channels

24

3.5V/5V supply voltage terminal
