Replacement verdict
Not a drop-in replacement
The 74HC238D and 74HC241D,652 are functionally unrelated logic ICs and cannot serve as substitutes for one another. The 74HC238D is a 3-to-8 line decoder/demultiplexer, while the 74HC241D,652 is an octal non-inverting buffer/line driver with 3-state outputs. Their differing logic functions, output configurations, pin assignments, and package types make direct replacement impossible without circuit redesign.
