Diode–transistor logic (DTL) is the direct ancestor of _____________(a) Register-transistor logic(b) Transistor–transistor logic(c) High threshold logic(d) Emitter Coupled LogicThe question was posed to me in an online quiz.I would like to ask this question from Diode-Transistor Logic(DTL) topic in section Logic Families of Digital Circuits

Answer»

Correct choice is (b) Transistor–transistor logic

The best I can explain: Diode–transistor logic (DTL) is a class of digital circuits that is the DIRECT ancestor of transistor–transistor logic. To overcome the SHORTCOMINGS of DTL, TTL CAME into EXISTENCE.
