ic components GAL16V8 and GAL20V8 with TTL and CMOS level compatible?

ic components GAL20V8 and GAL16V8 (hereinafter referred to as GAL) some time ago I
have used. Them with the TTL, CMOS compatible situation as follows:

1.GAL and the TTL of 74,74 LS, 74ALS series are compatible;

2.GAL is compatible with the CMOS of the 74HCT series, which is not compatible with the 
74HC series, because the 74HC series of Vih (min) = 3.5V, GAL's Voh (min) = 2.4v.

3.GAL is not compatible with the electronic components 74HC series is not to say they can not be mixed, the general solution is as follows, for reference: 74HC series logic level when driving GAL compatible; electronic component GAL 74HC Series driver circuit is required in the GAL and power output of between the access pull-up resistor.

An obvious question about electronic components

Essentially still stuck in a 1950s time warp where it comes to passive electronic components. This raises an obvious question: What if someone figured out a way to do  for passive components what past pioneers did for active ones? The results would be  revolutionary.

Change, development is the outlet of electronic component market,For future  development,Since the structure of the various amalgamated ceramics is so precisely  controllable, the kinds of tolerances required to shrink passive ic components are also  achieved.

Recommend a book - Electronic and Electrical Servicing

There is a book is very good, Worth watching,that is electronic component and Electrical Servicing,
Main content follows:

Electronic and Electrical Servicing Level 3 is the key to success in City & Guilds / Electronics Examination Board courses in electronic servicing, providing a thorough grounding in the electronics and electrical principles required by service engineers.

Ian Sinclair and Geoff Lewis have been the leading authors of books for electronic servicing courses for over 20 years, helping thousands of students through their college.

Though not a professional introduction electronic components or ic components,also has a certain value, Suggest you look at Electronic and Electrical Servicing.
