It's complicated. U.S. EMV credit is (virtually) all chip and signature. Debit is split between PIN and signature. US Debit Common AID is Online PIN, but you can legally do PIN bypass ("no cvm") or even fall back (or have user select) the card brand's application on the card (instead of the US Debit Common AID), in which case for Visa it will be signature and for Mastercard it will be online PIN. Politics and posturing.
