Frequently asked questions
Can SN74AHCT1G02DCKR be used in a 3.3V system?
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.
What is the equivalent or alternative for SN74AHCT1G02DCKR?
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.
