Each logic family has a noise margin (also called "noise immunity") specified by the manufacturer.
Manufacturers guarantee that the digital logic will still produce correct results even when some small amount of noise is superimposed on a gate output signal.
The maximum amount of such noise that manufacturers are willing to guarantee is the noise margin.
In order from highest to lowest noise immunity:
high-threshold logic: ???
CMOS has a noise margin of 2.95 volts with a 10 V power supply.
CMOS has a noise margin of 1.45 volts with a 5 V power supply.
CMOS has a noise margin of 0.6 volts with a 3 V power supply.
TTL has a noise margin of 0.3 volts.
integrated injection logic (IIL): ???
Noise immunity is the ability of a system to perform even when there is noise present. The higher the level of noise a system can still operate under, the higher the noise immunity.
Noise margin refers to the difference between the actual voltage levels of a digital signal and the threshold levels required for reliable recognition of logic states, providing a buffer against noise interference. Noise immunity, on the other hand, is the ability of a system to withstand external noise without affecting its performance or accuracy. Together, they are crucial in ensuring reliable digital communication and signal integrity in electronic circuits, especially in environments with potential electromagnetic interference. High noise margins and strong noise immunity enhance a system's robustness against disturbances.
The headphones that are rated the highest for noise cancellation are Bose headphones. They are recommended for long flights and for times when you will want to cancel out outside noise.
The 4039 CMOS NAND gate is an integrated circuit that contains multiple NAND gate functions, typically used in digital logic applications. It operates on a low power supply, making it suitable for battery-operated devices. The chip can perform logic operations with high noise immunity and low static power consumption. It is part of the CD4000 series of CMOS logic devices, which are widely used in various electronic circuits.
