    \$\begingroup\$ Yes, IDT is the manufacturer. Very good parts, I designed IDT into many circuits in the late '80s and early '90s. Their FCT logic gates were very fast, altho static sensitive. Had to use ESD mats and be strapped to the mat when handling bare components. \$\endgroup\$

From what I could find, the manufacturer is Integrated Device Technology (hence the integral sign, it's part of their logo).

The chip is most likely the 7164 series asynchronous static RAM.
