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.


Which has a shorter propagation delay TTL or CMOS?

TTL


Which logic family has the least propagation delay?

Here are the propagation delays for these gatesa) ECL = 2nsb) TTL = 1.5-33ns depending on the type of TTL. Conventional TTL is 9ns, Advanced Schottky TTL is 1.5nsc) RTL = 25nsd) CMOS = 5-20ns depending on if it is conventional CMOS, TTL pin compatible CMOS, high speed TPC CMOS or TTL compatible CMOSSo the fastest would be the Advanced Schottky TTL (74ASxx) at 1.5ns but the choice simply said TTL which I would interpret as Conventional TTL (74xx/54xx) which would have a propagation delay at 9ns.So the winner is ... (a) ECL which has a propagation delay at 2ns.


What is the difference between TTL and CMOS interms of fan infan outlogic levelspropagation delay?

The power dissipation of CMOS devices is around 100 times lower than the value of power dissipation for TTL. This makes CMOS more suitable for devices to run on battery power and devices allows like mobile phones to have a longer batter life. CMOS devices only use power when switching from one state to the other state (high to low, or low to high) so on they need power for less of the time than TTL devices which use current and dissipate power all the time that they have a power supply.


Why you prefer cmos design instead of nand or nor logic?

Since CMOS can be NAND and NOR logic this question seems to make little sense. However. If you by any chance think about CMOS Design versus TTL Design then this is a most interresting question. CMOS drain little current at low speed. As speed increases, the drain increases. TTL drain much the same current no matter the speed. There have been made TTL families that only use a little current. This will some times make this family preferable to CMOS. Especially true regarding high frequency logic circuitry. The benefit from TTL is that one output can source 8-14 inputs (Depending on family) CMOS is an ideal choice for low frequency battery operated equipment. It does not provide long batterylife at high frequencies though as drain of current increases.

What is a typical advantage of CMOS over TTL?

TTL stands for Transistor-Transistor-Logic. N-MOS is a type of a metal oxide semiconductor technology. TTL is faster, but generally uses more power. MOS based devices are slower, they and they use less power. Speed is an issue when dealing with high speed data processing.


What is the most used ic among ttl and cmos?

Can a ttl chip drive a cmos chip without modification?

A TTL chip can drive a CMOS chip without modification if the CMOS chip is designed to do so. Many large scale CMOS chips, such as microprocessors, have LS (or equivalent) TTL IO pins, so you can drive them directly. In the absence of that, you can use a pull up resistor, but you need to look carefully at fan-in, fan-out, rise time, fall time, and power requirements, in order to assure proper operation. It is best to use chips that are designed for the application, such as TTL to CMOS buffers.
