{| ! CMOS ! TTL | CMOS has good packing density. TTL takes up more space CMOS has better noise immmunity. TTL has a smaller noise immunity range CMOS has a large fan out. TTL can power less inputs CMOS consume less power. TTL use more power CMOS are highly static sensitive. TTL IC's tend to be less susceptible to static electricity CMOS uses FETS (Field-Effect Transistors) TTL uses BJTs (Bipolar junction Transistors CMOS can run with a range of supply voltages. TTL IC's run with a 5V supply. CMOS uses Vdd and Vss for it's power connections TTL uses BJTs (Bipolar junction Transistors CMOS takes a lot less power and is therefore suitable for battery applications, but generally speaking can't run as fast. TTL devices can drive more power into a load. CMOS chips can be damaged by static electricity: even a static jolt that you or I can't feel might destroy a CMOS chip! |}

What is logic family in digital electronics?
Transistor Transistor Logic. Main feature is cheap and old technology. Drawbacks it has limited speed and fan IN-OUT.
How does CMOS work?
CMOS is the little battery in the computer's motherboard which keeps the computers internal clock running.
What is ttl circuit?
A digital circuit composed of bipolar junction transistors (BJTs). Widely used in all variety of electronic applications, especially prior to CMOS circuits becoming popular, TTL superseded the earlier RTL (resistor-transistor) and DTL (diode-transistor) logic designs, which used more power. In TTL, transistors are used to both isolate inputs and perform the logic switching. A "TTL" designation on a circuit input or output indicates a digital circuit rather than analog.Read more: transistor-transistor-logic-electronics
What is Bulk resistance in terms of basic electronics?

What is the Ic number of 8 input x-or gate?
TTL 74 86 series or CMOS 4030
How cmos logic families works in negative temperatures?
CMOS logic families tolerate low temperatures because they are designed to. I suppose the why is not public because those would be trade secrets.
What are the Disadvantages of cmos over pmos and nmos?
CMOS and NMOS are two logic families. As the name itself indicates, CMOS is complementary Metal Oxide Semiconductor technology. It uses both PMOS and NMOS transistors for design. Whereas, NMOS logic family uses only NMOS FETs for design.
Which logic family dissipates the minimum power?
Cmos logic family, because it has no resistors attached who consume active power.
What are the blocks in logic gates?
The blocks in a logic gate depends on the logic family we use.A logic gate is designed using a specific logic family. The logic families can be DTL, TTL, CMOS etc.The blocks are different for different logic families.The various blocks in various logic families are:Diode logic: diodes and resistorsDTL logic : diodes and resistorsTTL logic : transistors and resistorsNMOS logic: only NMOS FETsPMOS logic: Only PMOS FETsCMOS logic: Both NMOS and PMOS FETsBiCMOS Logic: both transistors and FETs.
What is the different of logic families?
Logic families refer to groups of digital logic circuits that share similar characteristics, such as voltage levels, power consumption, and speed. Common logic families include TTL (Transistor-Transistor Logic), CMOS (Complementary Metal-Oxide-Semiconductor), and ECL (Emitter-Coupled Logic), each offering trade-offs between speed, power efficiency, and complexity. TTL is known for its robustness and moderate speed, CMOS boasts low power consumption and high density, while ECL provides the fastest switching speeds at the cost of higher power use. The choice of logic family depends on the specific requirements of an application, such as speed, power consumption, and integration density.
Why is a TTL logic gate faster than a CMOS logic gate?
The switching time (on and off) of the TTL logic gate is very fast in comparison with CMOS logic gate. However, they could not tolerate higher range of power supply.
What is the functions of cmos to the motherboard?
CMOS (complementary metal oxide semi conductor) is a logic family. A logic family refers to the way of implementing logic. Using this technique, logic gates are realized. The combination of several logic gates forms a digital circuit or integrated circuit (IC). A mother board is also an IC. The technique used to realize it is CMOS logic.
What is fastest logic family from ecl and cmos?
ecl
Which logic family has lowest power dissipation?
cmos
Why cmos are ratioless logic device?
because its a balanced device
What is advantage of CMOS setup?
CMOS is a type of technology for constructing integrated circuits. One advantage of this setup is less waste heat compared to NMOS logic or transistor-transistor logic.
How do you compare ttl logic and cmos logic?
The logic functions for both families of devices are the same. They differ only in their performance and other characteristics. TTL stands for Transistor-Transistor Logic. Advantages include higher speed, better current handling and relative immunity to static discharge. Disadvantages include more power consumption, output high voltage drops and fixed supply voltages (typically 5 volts). CMOS stands for Complimentary Metal Oxide Semiconductor. Advantages include better voltage output, better input voltage tolerance, variable supply voltages, higher density and much lower power consumption (although this increases with frequency). Disadvantages include sensitivity to static electricity and less current handling capability. Most new product development is in the CMOS family due to its more desirable characteristics. TTL and CMOS families contain many "sub-families" designed with special characteristics for specific applications. For instance, some CMOS families can handle greater current, function at higher speeds or operate at much lower voltages. Texas Instruments has more than 40 families of products under CMOS and TTL.
