{| ! 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! |}

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.

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.


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.


What is meant by standard load in digital electronics?

One standard load is the load of a typical input of a specified logic family. This is more relevant with bipolar logic families (e.g. RTL, DTL, TTL, ECL, I2L) than MOS logic families (e.g. NMOS, CMOS). Outputs of devices in these logic families are then rated by the number of standard loads they can drive. However when crossing between logic families (e.g. LS TTL to S TTL) the concept of standard loads is less useful and actual high/low state input current loading and output drive capability calculations should usually be made.
