Replacement verdict
Not a drop-in replacement
The 74VHC245FT and 74VHC00FT are not functionally interchangeable. The 74VHC245FT is an octal bus transceiver with 3-state outputs and dual enable controls, while the 74VHC00FT is a quad 2-input NAND gate. Their logic functions, channel configurations, pin assignments, and control interfaces are fundamentally different, making direct substitution impossible without complete circuit redesign.
Different logic function
Different channel count
Different pin assignment
Different control interface
