TTL stands for Transistor-Transistor logic, and it is a classification of cohesive circuits. CMOS stands for Complimentary Metal Oxide Semiconductor. TTL circuits employ BJT's while CMOS allows a much higher density of logic functions in a single chip compared to TTL. TTL circuits consume more power in comparison to CMOS circuits at rest.
CMOS chips are a lot more vulnerable to static discharge compared to TTL chips. There are CMOS chips which possess TTL logic and are meant for replacements for TTL chips. CMOS is another classification of IC's which use field-effect transistors in the design. The main benefit of CMOS chips is that there is a higher density within the same material.
CMOS and TTL are both classifications of integrated circuits. CMOS stands for ‘Complementary Metal Oxide Semiconductor’, while TTL means ‘Transistor-Transistor Logic’. The term TTL is gotten from the use of two BJTs (Bipolar Junction Transistors) in designing each logic gate. CMOS makes use of FETs (Field Effect Transistors) in the design. The basic advantage of CMOS chips over TTL chips is that it has a greater density of logic gates even within the same material.
A single logic gate in a TTL chip can be comprised of a large number of parts, as some extra components such as resistors are needed, while a CMOS chip with a logic gate can be comprised of just two FETs. Especially at rest, CNOS chips consume less power when compared to TTL chips. TTL chips are not really as delicate as CMOS chips when it comes to handling, because it is slightly vulnerable to electrostatic charge.
CMOS stands for Complementary Metal Oxide Semiconductor. It is a classification of integrated circuits that use field effect transistors. TTL is also a classification of integrated circuits and it stands for Transistor-Transistor Logic. CMOS is greater in density within the same material. One logic gate in a CMOS chip can contain less than two field effect transistors.
A TTL chip can include a number of parts such as resistors. Another advantage of CMOS chips is that it consumes less power. This can depend on a number of factors such as the clock rate. Due to these reasons, CMOS chips have become more prominent than TTL chips.
