16-BIT CONSTANT CURRENT LED DRIVER
SM16706P/SP/F/FN
GENERAL DESCRIPTION
The SM16706P/SP/F/FN are specifically designed
for LED display constant current drivers.
This constant current output circuits is able to setup
by external resistor (I
OUT
= 5 ~ 90mA).
This IC is monolithic integrated circuit designed to be
used together with Bi-CMOS process.
The devices consist of 16bit shift register, latch,
AND-GATE and Constant Current Drivers.
FEATURES
* Constant Current Output :
can setup all output current with one resistor
for 5 to 90mA.
* Maximum Clock Frequency :
