Hi ,

Can any one explain how we can drive 16 lcd digits by using hef4543 IC from at89c51 controller.(each hef ic for each digit). (In one of the existing designs we checked and extracted the information that,it is driving with hef4543 IC for each digit.In between he used a 74hc4514 decoder and CD 4054).

thanks and regards
