Q1:

What is the difference between the 54XX and 74XX series of TTL logic gates?

A 54XX is faster.

B 54XX is slower.

C 54XX has a wider power supply and expanded temperature range.

D 54XX has a narrower power supply and contracted temperature range.

ANS:C - 54XX has a wider power supply and expanded temperature range.

Bipolar transistors did its execution by small time but consume more power than that of MOS. And 54XX series of TTL has a range of -55 to +125.
