Replacement verdict
Not a drop-in replacement
The 74HC238D and 74HC273D,652 are functionally unrelated ICs: one is a 3-to-8 line decoder/demultiplexer and the other is an octal D-type flip-flop. They differ in logic function, input/output architecture, latching behavior, and pinout, so neither device can substitute for the other in an existing design.
Different logic function
Different output type
Different latching behavior
Different pinout
