Replacement verdict
Compatible functional replacement candidate
The 74HC244D and 74HC241D,652 are both octal non-inverting buffers with 3-state outputs in the same SO-16 package, making them functionally interchangeable in many designs. However, the 74HC241D,652 features a split enable architecture with separate active-low and active-high enable pins, whereas the 74HC244D uses two active-low enables. This difference requires careful validation of the enable logic in the target circuit before substitution.
