Replacement verdict

Not a drop-in replacement

The 74HC259D and 74HC245D,653 are functionally unrelated logic ICs and cannot serve as substitutes for one another. The 74HC259D is an 8-bit addressable latch with decoder and storage registers, while the 74HC245D,653 is an octal bidirectional bus transceiver with 3-state outputs. Their internal architectures, pin functions, and intended applications differ fundamentally, making direct replacement impossible without complete circuit redesign.
