DESCRIPTION

NAME

CLK

Clock input for data shift on rising edge

GND

Ground for control logic and current sink

Data strobe input

Serial data is transferred to the respective latch when LE is high.

LE

The data is latched when LE goes low.

LE has an internal pull-down resistor.

Output enable

When OE is active (low), the output drivers are enabled.

OE

When OE is high, all output drivers are turned OFF (blanked).

OE has an internal pullup resistor.

OUT0–OUT15

Constant-current outputs

R-EXT

SDI

Serial-data input to the Shift register

SDO

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

VDD

Supply voltage
