Hot selling spot ST2221C SOP24 SITI 5V16 bit constant current driver chip

Product Descriptions

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.
