Replacement verdict
Not a drop-in replacement
The 74VHC245FT and 74VHC02MTC are not functionally interchangeable. The 74VHC245FT is an octal bus transceiver with 3-state outputs, while the 74VHC02MTC is a quad 2-input NOR gate. They differ in logic function, channel configuration, pinout, and package type, making direct substitution impossible without redesign.
