'''Resistor-transistor logic''' (often referred to by its acronym, '''RTL''') was the earliest [[logic]] [[circuit]] family using [[bipolar]] [[transistor]]s; it was later essentially completely replaced by the later [[diode-transistor logic]].

The name comes from the fact that the logic functions were performed by [[resistor]] networks; the signal-amplification was performed by a [[transistor]]. The use of resistors was good in the pre-IC stage (when discrete transistors were expensive), but it limited the number of inputs.

Is it notable as being the logic family in the first [[integrated circuit]]s, produced by [[Fairchild Semiconductor]]; those ICs were used in the [[Apollo Guidance Computer]].

 The use of resistors was good in the pre-IC stage (when discrete transistors were expensive), but it limited the number of inputs. The use of resistors for the logic network also led to minimal [[noise immunity]], probably the biggest drawback of DTL.
