ST2225A  35輸出信道數(shù)字字母LED驅(qū)動芯片                     

      The  ST2225A  LED  display  driver  is  a  monolithic  CMOS  IC.  In  order  to  achieve continuous brightns control, the LED display brightns is controlled by setting a reference current through a variable ristor connected between a supply and a single pin.

       Featur:  Continuous brightns control; Serial data input; No load signal required for data latch;  Wide power supply operation;  TTL compatibility;  35 outputs, 20mA capability; Small package, SSOP48 and bare chip form

     Applications: Industrial control indicator; Relay driver; Dial clock, thermometer, counter, voltmeter; Instrumentation readouts
