Somehow the 7448 ic outputs are not changing even though the inputs are changing. The inputs are from a jk flipflop counter and im having trouble displaying the output of it in a 7 segment display.

It's just stuck to the output 9 or 0. Help.

What do you mean it works?
What happens when you connect pin-3 of SN7448 to GND?
My bad, connecting the pin 3 of the 7448 to GND turns on all of the led display of the 7segment.

I got it working by connection pin 5 to GND, it's labeled in the datasheet as RBI
