What is a TTL chip?
What is a TTL chip?
Transistor–transistor logic (TTL) is a logic family built from bipolar junction transistors. Some TTL chips are now also made in surface-mount technology packages. TTL became the foundation of computers and other digital electronics.
Why does IC start with 74?
The series 74 was a designation for commercial grade TTL (transistor to transistor logic, a family circuit characteristic) and 54 was a designation for military temperature of the same design. The family had more or less matched speeds, and drive levels called TTL loads.
What are TTL and CMOS?
CMOS stands for complementary metal-oxide-semiconductor is also another classification of ICs that uses the Filed effect transistor in the design. TTL stands for Transistor transistor logic. It is a classification of integrated circuits.
Which is better TTL or CMOS?
Which one is Better? The advantage of the CMOS over the TTL chips is that the CMOS has a higher density of logic gates within the same material. TTL chips consume more power as compared to the power consumed by the CMOS chips even at rest. A very minute amount of static electricity could cause damage to the CMOS chips.
What is meant by 74LS?
The 74LS (Low-power Schottky) family (like the original) uses TTL (Transistor-Transistor Logic) circuitry which is fast but requires more power than later families. The 74HC family has High-speed CMOS circuitry, combining the speed of TTL with the very low power consumption of the 4000 series.
How IC is named?
A lot of IC names are rather arbitrary: typically a prefix indicating manufacturer or series, and a number. However, in the case of that particular chip (and discrete logic chips in general), the name tells you a lot. The “SN” is a prefix specific to TI. The “74” indicates a 7400 series logic devices.
What is the only function of not gate?
Hint: A NOT gate is one of the logic gates (or one can say a Boolean Operator) which can take only one input signal and gives one output signal. The NOT gate works by inverting the original signal.
