Default Re: How do I test integrated circuits with a multimeter?

There is no easy way to function test ICs except perhaps basic logic gates - of course you can check any IC for dead shorts, though.

Since they all have completely different designs and functions, the only real good test is in the circuit it was designed for, and verify by substitution.

The same way to test a non-SMD part - you can measure it as long as it's not in parallel with anything else, or connected to any other circuitry that can throw off the measurements.

If in doubt, you still have to remove it and test out of circuit. There is no way around that.
