hello, i wish to design a 100 input priority checker using ten 10-line-4 line priority encoder (ic 74147) by cascading them.the output has to be displayed using 2-seven segment displays.This will thus enable me to display the highest priority input which is low as ic 74147 is an active low input chip.For eg if out of 0-99 inputs,85th input input is low..the seven segment display must display 85.please help me with the circuit of combining the cascaded priority encoders and the 7-segment display.
