Can continuity test cause component damage?
Can continuity test cause component damage?


Generally no. I have used ohmmeters to measure continuity on expensive aerospace electronics and was never concerned. Reliability engineers never warned us about risks.

For your example (LVTTL component), the part will never see a large voltage, the ESD protection circuit will limit the voltage. Connecting an ohmmeter is not the same as connecting a stiff voltage from a power supply. A stiff voltage probably would damage the part.

Some parts without ESD protection could be damaged by an ohmmeter if their absolute maximum input voltage was very low. These types of parts are not common.
