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 = 25^oC)
* 5V CMOS Compatible Input
* 16 pin DIP, SOP or SSOP package
