8-BIT CONSTANT CURRENT LED DRIVER SM16705P/F/FN GENERAL DESCRIPTION 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, ANDGATE and Constant Current Drivers.
FEATURES * 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 : Output-GND Voltage ≧0.
4V ≧0.
