I have a requirement to drive 12 nos of large seven segment displays … these are displays with segment drive voltage of 5.6V and current of about 20mA or so. ( three groups of 4 digits each )
I was wondering if a single HT16K33 could be the main driver and linked to the Common cathode displays through some buffer ICs ?
Since the HT16K33 can drive 16 digits i dont have to resort to any daisy chaining of the controllers .
Or is there any better way to do this ?
Any links or ideas to do this ?
