I stumbled upon a 16 pins MC14093BC (ceramic) chip from Motorola

45606

Has anyone ever seen these? (in the photo also the normal 14 pin version)

The 16-pin version looks like a forgery--or a mistake. Did you get it from China?

Quad 2-input Schmitt trigger

No, not from China as far as I know, found it in a big box of old parts from a swap meet.
I will try and identify the chip(s) at work with our digital IC tester.
