8-BIT CONSTANT CURRENT LED DRIVER

GENERAL DESCRIPTION

FEATURES

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.

* Constant Current Output :

can setup all output current with one resistor

for 5 to 90mA.

* Maximum Clock Frequency :

fCLK = 25 (MHz)

(Cascade Connect Operate,

Topr = 25oC)

* 5V CMOS Compatible Input

* 16 pin DIP, SOP or SSOP package

* Constant Output Current Matching :
