74LS147N 10:4 priority encoder not working... Answered
This is a follow up of this question- https://www.instructables.com/answers/Logic-circuit-to-generate-and-convert-3-bits-paral/
I set all the 10 inputs of the encoder high and was expecting to see all the 4 outputs give a high(4 LEDs were connected to the outputs to see this happen).But that wasn't the case and just 2 of the LEDs glowed.I tried different configurations on the inputs but all the time it was either these two LEDs that glowed or none .Can this ic power 4 LEDs directly from its outputs? Could I have wrecked the ic?
Something a bit off the topic- What should I keep in mind while mixing TTL and CMOS logic gates?
I powered the ic with 5 volts.
