"WebThe drawback of RTL is that when the transistor is turned on, current flows through the base and collector resistors, which results in significant power loss. More supply current is needed for this, and the RTL circuit should be kept cool. DTL has the benefit over RTL because diodes, rather than resistors, do the logic. This states that there is no " - How to turn on an npn bjt
