Abstract: Circuitry for enhancing the ability of digital circuits to drive highly capacitive loads is disclosed. This circuitry has particular utility when employed with logic circuits such as "TTL" (Transistor- Transistor Logic) and "DTL" (Diode-Transistor Logic). … The circuitry (15) comprises four transistors (T1, T2, T3A, T3B) and two resistors (R1, R2), at least one of the transistors (T1, T3A) being connected as a diode.
