Default Schematics nomenclature

Pins 12, 13 are latch enables that arent used so tied to ground. The tiny
€œtriangles€ are probably enable-low indicators.

Still not sure about €œn€, €œ#€, €œx€...

Pins 12 and 13 have a little triangle next to the pin; pins 1, 2, 15, 16
have
what looks like an €œn€; 3 and 14 have an €œx€.

Whats the meaning of these marks?

Thanks.
