Transistor Transistor Logic Circuit. This is a logic family which is mainly build up of npn transistors pn junction diodes and diffused resistors. Transistor transistor logic is a logic family built from bipolar junction transistors.
Sometimes ttl compatible logic levels are not associated directly. The circuit element that performs a single logical operation is known as a gate. The transistors are capable of a 400 fold modulation of electrical conductivity and by combining with metal nanoparticle diodes and resistors can be used to construct not nand and nor logic.

This is a logic family which is mainly build up of npn transistors pn junction diodes and diffused resistors. Transistor transistor logic is a logic family built from bipolar junction transistors. If both emitters are connected to the positive supply voltage logical high equivalent to a and b the transistor does not conduct. Digital logic circuits are manufactured depending on the specific circuit technology or logic families.
