The SN74AHCT1G02DCKR: Status is Active per TI's product lifecycle. The part is ROHS3 compliant. We source and quote it to order against an RFQ.
SC-70-5 (also called SOT-353). Five pins, surface-mount only.
No — this part requires a 4.5V to 5.5V supply. The input high threshold is 2V, which is above a typical 3.3V output's VOH, so it will not reliably detect a logic high at 3.3V.
A pin-compatible NOR gate in the same package is the 74AHC1G02 (e.g., SN74AHC1G02DCKR), which runs at 2V to 5.5V and is 3.3V compatible. For a NAND function, the SN74AHC1G00DBVT is a close peer but different logic type.
