Hello,

I would need help to find some suitable replacements for CD74HCT154EN and CD74HC154EN Integrated Circuits.

These devices were discontinued in 2016.

The only possible replacements in a DIP package would be the CD54HC154‍F3A and CD54HCT154‍F3A. It might be a better idea to use a SOIC-to-DIP adapter.
