What is 7432 ic?
The 7432 is a quad two input OR gate with TTL levels.
Difrance between ic and ttl?
ic refers to integrated circuits and ttl refers to transistor transistor logic. ttl is a family which provides the basic or former structure of logic gates for example different logic gates such as NAND,NOR etc can be made out with the help of transistors connected in a specific manner. integerated circuits are the combination of logic gates presented on a base with equal number of input pins . for example IC-7408 contains 14 pins
What is a TTL-compatible output?
Compatibility in TTL means that the output of one TTL device can be used to drive the Input of the other TTL device , This because the low and high output window fit inside the low and high input window/profile TTL stand for Transistor Transistor Logic, so any voltage between 0 and 5 volt is compatible where any voltage between 3V and 5V is logic 1 and zero volt is logic 0
What is the power dissipation for TTL?
power dissipation of a logic circuit is usually defined as the supply power required for the gate to operate with a 50% duty cycle at a specific frequency.
Which has a shorter propagation delay TTL or CMOS?
TTL
Explain working of ttl for NAND gate?
In the NAND gate, the transistors play the role of the switches. The emitter and the collector voltages vary in the opposite phase.
What type of gate is the 74LS00?
The 74LS00 is a quad two input NAND gate with low power schottkey TTL implementation.
What is the IC number for 3-input nand gate?
TTL 7410CMOS 4023DTL 962/C
How NAND gate works?
A: NAND implies not and to be true both input must be hi or true <> There are two flavors of NAND gate. The positive input/negative output NAND will have a low output if and only if both inputs are high. The negative input/positive output NAND will have a high output if and only if both inputs are low.
What are the characteristics of ttl nand gate?
A: It is simply a function of negating a true input, the other characteristics s that it is limited in fan-in fan -out capabilities
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 7432 ic?
The 7432 is a quad two input OR gate with TTL levels.
Ic number of or gate?
Ttl: 7432, 744075cmos: 4071
What is the function of 74LS08?
74LS08 is a quad two-input AND gate with LS-TTL logic levels.
What is the Ic number of 8 input x-or gate?
TTL 74 86 series or CMOS 4030
Why an open ttl gate behaves as a logic high input?
because TTL have a bias input setup to eliminate noise therefore the output will follow the logic one input if left open
Is it possible to make any logic gate from only use of NOT gate?
NAND and NOR logic gates are the two pillars of logic, in that all other types of Boolean logic gates (i.e., AND, OR, NOT, XOR, XNOR) can be created from a suitable network of just NAND or just NOR gate(s). They can be built from relays or transistors, or any other technology that can create an inverter and a two-input AND or OR gate.Hence the NAND and NOR gates are called the universal gates, and this basic understanding should be observed by all undergraduate electrical engineering students.But, for reasons of indulgence on the topic, lets go into a further explanation, of why NOT gates cannot be used. Take for example the NAND gate. Lets build its truth table.[1]A0A1 | B--------00 | 101 | 110 | 111 | 0States (00), and (11), can be implemented using a 2-input NOT gate.A0..A1 =|>- BComplications arise, however with building a solution for states (01), and (10). The following is not a viable solutionA0 ---|>-----|>--- B (Not viable)The problem has to do with the limited memory of the system:Imagine two signal paths, running in parallel, to a mutual destinationBranch 1 - ..---|>-----|>---..Branch 2 - ..---|>----------..If each inverter ( NOT gate ) has to manipulate ( invert ) the signal, then a gate delay Dgate is introduced by each gate. Thus the 1st branch will have a gate delay of 2; whereas the 2nd branch only has a gate delay of 1.The faster branch ( Branch 2 ) will usually reach its destination first, which inherently introduces timingissues.This can happen with other forms of TTL, such with NAND gates. But the solution is to introduce a latch. A latch is essentially a 1-bit memory cell. [1]Branch 1 - ..---|>-----|>--..Branch 2 - ..---|>-----(L)--....But then how do you build a latch, if a latch is composed of TTL NAND gates [2], and the initial timing issues, involving these gates, hasn't been resolved?And it is this contradiction which thus preempts the use of a NOT gate as the foundation for a homeomorphic system.There has been a proposed solution, in which a solid-state capacitor is substituted in place of a latch ( I leave it up to the reader to decide for himself ), it appears to be proprietary technology in Iran.
