It appears these are 8-bit storage registers (2x4bit), so essentially 8 D-type latches. Similar to the later 74LS374.

I don't know exactly, maybe the number - is a series to a particular product. It doesn't look like a number of batch . The triangle on Soviet products denoted military acceptance, for military products, but here the triangle is turned from top to bottom
