Transistor–transistor logic (TTL) is a class of digital circuits built from ____________
A. JFET only
B. Bipolar junction transistors (BJT)
C. Resistors
D. Bipolar junction transistors (BJT) and resistors
Answer:D
Transistor–transistor logic (TTL) is a class of digital circuits built from ____________
A. JFET only B. Bipolar junction transistors (BJT) C. Resistors D. Bipolar junction transistors (BJT) and resistors
Explanation: Transistor–transistor logic (TTL) is a class of digital circuits built from bipolar junction transistors (BJT) and resistors. However, resistors have a small role to play and both logic gating and amplifying functions are performed by the transistors.
