XOR gate number 7486?

Question

I was looking for a XOR gate with the number 7486. I looked through my big box of ICs and I found some that are 74LS86. I was wondering if the 74LS86 is the same as the 7486.

Answer 1

Yes, they are the same--sort of. The pin outs and logic are identical. So are the high and low voltage levels.

The LS designation stands for Low Power Schottky. The fanout will be slightly lower than the standard TTL 7486. However, power consumption should be lower.

In "most" cases, the 74LS86 would be a drop-in replacement for the standard 7486.
