    Hi, Iam making the project on water level indicator using IC’s 74147 and 4511 and a 7 segment display. As iam a beginner, want to know that do i need to program both the IC’s or not??. and is there any difference in IC 74HC147 and IC 74147 as names seems to be different? And what is the ampere i need to provide with 5v at the input?
    Thank you.
