Question

TTL inputs are the emitters of a ____________

(a) Transistor-transistor logic

(b) Multiple-emitter transistor

(c) Resistor-transistor logic

(d) Diode-transistor logic

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

I would like to ask this question from Transistor Transistor Logic(TTL) in portion Logic Families of Digital Circuits

Answer 1

Correct option is (b) Multiple-emitter transistor

The best I can explain: TTL inputs are the emitters of a multiple-emitter transistor.
