Replacement verdict
Not a drop-in replacement
The 74VHC245FT and 74VHC04FT are not functionally interchangeable. The 74VHC245FT is an octal bidirectional transceiver with 3-state outputs, while the 74VHC04FT is a hex inverter with unbuffered outputs. They differ in logic function, channel count, output type, and pin configuration, making direct substitution impossible without circuit redesign.
Different logic function
Different channel count
Different output type
Different pin configuration
