Why transistor is used in logic gates?
The use of transistors for the construction of logic gates depends upon their utility as fast switches. When the base-emitter diode is turned on enough to be driven into saturation, the collector voltage with respect to the emitter may be near zero and can be used to construct gates for the TTL logic family.
What is a TTL load?
TTL Load Circuits A device through which an electric current flows and which changes electrical energy into another form. Power consumed by a device or circuit in performing its function. A load my be represented by a resistor and capacitor.
What type of transistor is used in TTL logic?
The Transistor-Transistor Logic (TTL) is a logic family made up of BJTs (bipolar junction transistors). As the name suggests, the transistor performs two functions like logic as well as amplifying. The best examples of TTL are logic gates namely the 7402 NOR Gate & the 7400 NAND gate.
Why the transistor operates as NOT gate?
The NOT gate is the basic logic gate among all the gates. It gives only one output which is the negation value of the corresponding input. When the input is forced to low value it gives high value at the output and vice – versa.

What do you need to know about TTL logic?
What Does Transistor-Transistor Logic (TTL) Mean? Transistor-transistor logic (TTL) is a class of integrated circuits which maintain logic states and achieve switching with the help of bipolar transistors. One of the prominent features of transistor-transistor logic signals is the ability of the inputs of the gate rise to the logical “1” if
What does TTL stand for in integrated circuit?
Transistor-transistor logic (TTL) is a class of integrated circuits which maintain logic states and achieve switching with the help of bipolar transistors.
Are there any disadvantages to using transistor logic?
Transistor-transistor logic is largely immune to damage from static electricity discharges, unlike CMOS, and are also relatively inexpensive compared to CMOS. One major disadvantage of transistor-transistor logic is its high current consumption.
