I don't know about Current Transfer Logic, but my vague recollection
(probably wrong) was that it used Signetics Utilogic II and Fairchild
CuL or CTuL families. There are three different years' Utilogic
databooks on Bitsavers. There is some data on CuL and CTuL in the 1969
Fairchild Data Catalog on Bitsavers.

If it's not any of those, then I have no idea.
