A disadvantage of DTL is ___________(a) The input transistor to the resister(b) The input resister to the transistor(c) The increased fan-in(d) The increased fan-outI got this question in exam.I would like to ask this question from Diode-Transistor Logic(DTL) in portion Logic Families of Digital Circuits

Answer»

The correct OPTION is (b) The input resister to the TRANSISTOR

Best EXPLANATION: A disadvantage of DTL is the input resistor to the transistor and its presence tends to slow the circuit down. Hence limiting the speed at which the transistor is able to SWITCH states. Thus, the propagation delay increases.
