Diode-transistor logic

Diode-transistor logic (often referred to by its acronym, DTL) was an early logic family; it replaced the earlier resistor-transistor logic family, and was in turn soon essentially completely replaced by transistor-transistor logic.

The name comes from the fact that the logic functions were performed by diode networks; the signal-amplification was performed by a transistor.
