Replacement verdict

Not a drop-in replacement

The 74HC238D and 74HC245D,653 are not functionally interchangeable. The 74HC238D is a 3-to-8 line decoder/demultiplexer with active-low outputs, while the 74HC245D,653 is an octal bidirectional bus transceiver with 3-state outputs. Their logic functions, pin configurations, and I/O structures are fundamentally different, making direct substitution impossible without circuit redesign.
