A 74HC147 priority encoder has ten active-LOW inputs and four active-LOW outputs. What would be the state of the four outputs if inputs 4 and 5 are LOW and all other inputs are HIGH?

Please give me the clear explanation.

This is wrong the answer should be C because with 0101 the LSB is A0 and MSB is A3 the answer A is technically 1010 which is a decimal 10.

For the priority encoder, priority is increasing from 0 to 10. Here we giving 5 and 4 as zero, so priority is higher for 5.
5 = 0101.
5 = 0101.

@Bijendra Kumar.
Why the priority is higher in I4 and not I5?

@All.
Here we are using the BCD value at the output it's not a normal encoder it is different.
