Question

What is LVT logic?

(a) Lower threshold voltage

(b) Lower supply threshold voltage

(c) Lower supply voltage while retaining TTL logic levels

(d) All of the Mentioned

I had been asked this question in an international level competition.

I'm obligated to ask this question of BiCMOS Logic Circuits topic in division Logic Families of Digital Circuits

Answer 1

The correct option is (c) Lower supply voltage while retaining TTL logic levels

For explanation I would say: LVT stands for Low Voltage BiCMOS Technology which is an integration of less power dissipation and less noise of CMOS along with the high switching speed and output drive of BJT. LVT logic is nothing but the lower supply voltage while retaining TTL logic levels.
