8-BIT CONSTANT CURRENT LED DRIVER

The SM16705P/F/FN are specifically designed for

LED display constant current drivers.

This constant current output circuits is able to setup

by external resistor (IOUT = 5 ~ 90mA).

This IC is monolithic integrated circuit designed to be

used together with Bi-CMOS process.

The devices consist of 8bit shift register, latch, AND-

GATE and Constant Current Drivers.
