LUB750B IC

If LUB750B is related / an alternate / mis reference to that or in the same family,, and then I list what you should do to verify, plus how to list its selling points, tags etc in case you manage to find full specs.

• 10 Macrocell Electrically Programmable Logic Device (EPLD)  enabling  moderate combinational / sequential logic without needing full FPGA overhead.
• Fast speed: 15ns propagation delays, suitable for time critical logic functions.
• Operates at 5V logic level, standard for many older digital/embedded systems.
• Packaged in 28lead PLCC (J lead) with 11.51mm ×11.51mm footprint, suitable for sockets or direct mounting.
