Maybe too general for General Hardware, not technical enough for Highly Technical. So here it is.
An eval board schematic (PDF, pg13) I'm looking at for the ADE7753 shows some AND gates inserted into some data lines - except each gate has both of its input pins tied together. They're tied right together on the PCB layout as well, without any kind of crazy routing paths.
Are they acting as some kind of noise filter, or an intentional source of propagation delay, or what? The only mention of them in the text is in the Bill of Materials.
