What is this SMD marked E6H

[Kg74]

I am trouble shooting a Celestron Hand Controller and do not know what this part is. It appears to be marked E6H -located to Right of O chip under U12. Any ideas?

probably a ttl logic gate

"ELM7SU04B is CMOS unbuffer inverter IC". Marking is E6x.

Thank you - I searched the part and reviewed the data sheet. I cannot find the part at any of my normal sources - or anywhere for that matter. I am not too sharp here, but it appears a Toshiba TC7SU04F may be an equivalent. I asked Bing AI and it puked out nonsense and an answer of "no". Any thoughts?

04 is just an invertor - loads of companies make them.
slightly different part numbers for each company though.

Thanks both of you. I think I have enough to narrow the search.
