What are the different types of integrated logic families?
What are the different types of integrated logic families?
Resistor Transistor Logic (RTL) Diode Transistor Logic (DTL) Integrated Injection Logic (IIL or I2L) Transistor Transistor Logic (TTL)
What are the different families of logic gates IC’s compare different families?
These families are listed below:
- Diode Logic (DL)
- Resistor-Transistor Logic (RTL)
- Diode-Transistor Logic (DTL)
- Transistor-Transistor Logic (TTL)
- Emitter Coupled Logic (ECL)
- Complementary Metal Oxide Semiconductor Logic (CMOS)
What is a logic family compare ECL and TTL families?
ECL is based on use of current steering switch realised using differential transistor pair. ECL eliminates saturation and improves speed but uses more power than other logic families such as TTL and CMOS. ECL is fastest logic family among all and this is due to avoidance of saturation region for application.
Which is the first integrated logic family?
The first, and oldest, family is TTL. TTL stands for ‘transistor-transistor logic’, this logic family having replaced the older (now obsolete) DTL—diode-transistor logic. The second logic family is CMOS (pronounced ‘sea-moss’) which stands for ‘complementary metal oxide semiconductor’.
Which one is the most popular and widely used IC family?
Over the years, the most widely used overall family has been the 7400 series ICs. Initially launched as straight 7400 series integrated circuits, this logic IC family has spawned many variants which has enabled it to remain in use until this day.
Why CMOS logic family is better than bipolar family?
The main advantage of CMOS logic family is their extremely low power consumption. This is because there is no direct conducting path from Vdd to ground in either of input conditions. So there is practically zero power dissipation in STATIC conditioms.
How many logic families are there?
Four major logic families that predominated from the 1970’s through the 1990’s are Transistor-Transistor Logic (TTL), Complementary Metal-Oxide-Semiconductor Logic (CMOS, pronounced sea-moss), Low Voltage TTL Logic (LVTTL), and Low Voltage CMOS Logic (LVCMOS). Their logic levels are compared in Table 1.4.
Which logic is the fastest of all the logic families?( Are 2 points TTL ECL CMOS RTL?
Explanation: The full form of ECL is emitter-coupled logic. 2. Which logic is the fastest of all the logic families? Explanation: ECL is the fastest of all the logic families because of the emitters of many transistors are coupled together which results in the highest transmission rate.
Which logic is the fastest of all the logic families?
Emitter-coupled-logic (ECL)
Emitter-coupled-logic (ECL) is a BJT logic family that is generally considered the fastest logic available.
Which logic family has the highest power dissipation per gate?
(a); ECL has the highest power dissipation.
What are the different types of logic families?
Logic Families indicate the type of logic circuit used in the IC. The main types of logic families are: Speed: Speed of a logic circuit is determined by the time between the application of input and change in the output of the circuit. Fan-in: It determines the number of inputs the logic gate can handle.
Which is better in power consumption between different logic families?
Thus Figure 6 shows the graphical representation of power overall performance of CMOS logic family is better in consumption in different logic families. It can be seen that comparison with other logic families. TTL logic families consume sume highest power and minimum power dissipation is in CMOS logic family.
How does CMOS compare to other logic families?
It can be seen that though outperforms all the logic families. delay in CMOS is high than TTL, but power-delay power product of CMOS is minimum compared to other logic families. Thus Figure 6 shows the graphical representation of power overall performance of CMOS logic family is better in consumption in different logic families.
What are the advantages of TTL logic families?
Advantages of the TTL logic families include high switching speed (125 MHz), less noise and more current (3 mA) driving capability. Figure shows TTL NAND gate.
