Which TTL sub-family has maximum speed ________________.
Schottky-clamped TTL sub-family has maximum speed.
Transistor–transistor logic(TTL):-
Transistor–transistor logic(TTL) is a logic family built from bipolar junction transistors. Its name signifies that transistors perform both the logic function and the amplifying function; it is the same naming convention used in resistor–transistor logic (RTL) and diode–transistor logic (DTL).
TTL integrated circuits (ICs) were widely used in applications such as computers, industrial controls, test equipment and instrumentation, consumer electronics, and synthesizers.
schottky-clamped transistor–transistor logic:-
A schottky transistor is a combination of a transistor and a schottky diode that prevents the transistor from saturating by diverting the excessive input current. It is also called a schottky-clamped transistor.
