Question

What does ALVT mean?

(a) All lower supply voltage while retaining TTL logic levels

(b) ABT lower supply voltage while retaining TTL logic levels

(c) Advanced version of LVT logic

(d) All version of LVT logic

This question was posed to me in semester exam.

The origin of the question is BiCMOS Logic Circuits in chapter Logic Families of Digital Circuits

Answer 1

Correct choice is (c) Advanced version of LVT logic

To elaborate: ALVT stands for Advanced Low Voltage BiCMOS Technology (ALVT). It is a faster version of LVT family. It is an integration of less power dissipation and less noise of CMOS along with the high switching speed and output drive of BJT.
