Try Chapter 1 (Digital Logic Circuits) of M. Morris Mano, Computer System Architecture, Third Edition, Prentice-Hall 1993. I used to use earlier editions of Mano while teaching in the 1980's and they went over quite well.
You might try also Chapter 2 (Fundamentals of Digital Logic) of Douglas E. Comer, Essentials of Computer Architecture. Comer writes for people, and he writes well.
If you want everything put together densely then try Appendix B: Digital Logic of William Stallings, Computer Organisation and Architecture, Seventh Edition.
