Datasheet from a specific SO-8 component

[RMell.1]

Hi, I actually working on a IHM that uses a SO-8 IC Maked as 4F100@ (EZ738) that I cant find anything on web. Could You Help me to solve the issue here? I´m sure that the unit is a common IC but, unfortunatelly, seems to be a proprietary component. Anyway, I thank you in advance.

Perhaps some context information, i.e. analog or logic, approximate year of production of the board ?

The was once a 74x100 logic IC (and a 74F100 version), but those had 24 pins.

Just not expecting to be supported so quickly! Thanks!

I'll take some shots from the board to help You find some info about it. The HMI is a Beijer/Mitsubish E1151. I attached a pic from it. Further I'll send the photos from the ic.

One more time, thank you for your support.
