Function

GND terminal for control logic

Input terminal for serial data for data shift register

Input terminal for clock for data shift on rising edge

Input terminal for data strobe When the LATCH=High-level, data is no latched. When

ithe LATCH=Low-level, data is latched.

Constant-current output terminals

OUT 0 ~ 15

Input terminal for output enable.

ENABLE All outputs (OUT0 ~ OUT15 ) are turned off, when the ENABLE=High-level.

And are turned on, when the ENABLE=Low-level.

SERIAL-OUT Output terminal for serial data input on SERIAL-IN terminal

R-EXT Input terminal used to connect an external resistor.

This regulated the output current.

VDD
