ST2221C 16-Bit Constant Current LED Drivers ST2221C General Description The ST2221C is specifically designed for LED and LED DISPLAY constant current drivers.
The value of constant current can be varied using an external resistor (Iout = 5 ~90mA).
The devices include a 16-bit shift registers, latches, and constant current drivers on a single Silicon CMOS chip.
Features z Constant Current Output : Current with one resistor for 5mA to 90mA z Maximum Clock Frequency : 25MHz (Cascade Operation) z 5V CMOS Compatible Input z Package : DIP24 , SOP24, SSOP24 z Constant Current Matching: (Ta = 25°C、VDD = 5.
