the pullup or pull down resistance in the diode logic gate makes it a high output resistance device.If u try to drive another diode logic gate with it the output voltage of the first gate will be affected by the resistance in the second gate.A diode logic gate should always drive a high input resistance input.
What else can I help you with?
What are the characteristics of Diode transistor logic?
relatively large propagation delay.
What are the diode logic gate?
A logic gate composed only of diodes and resistors. The only types are AND gates and OR gates. However the number of layers of logic that can be implemented are severely limited due to losses in these gates.
Need of program Logic controllers?
Program logic controllers are used to control the operation of most systems.
What is an XNOR gate?
An XNOR gate is a logic gate performing a Boolean logic XNOR operation, also known as an equivalence gate.
What are the advantages of transistor-transistor logic?
Transistor-transistor logic (TTL) is a class of digital circuits built from bipolar junction transistors (BJT) and resistors. It is called transistor-transistor logic because both the logic gating function and the amplifying function are done by transistors.To know about the advantages of TTL logic family, one should have a basic idea about RTL, DTL etc. Diode logic (DL) uses diodes to implement logical functions like AND and OR. But the disadvantage is that it can not perform NOT operation. As AND and OR are not complete functions by themselves, they can not perform several logic functions without NOT. Hence, there was a need for some device which can perform a NOT function as diodes can not. That device is a transistor. Then came the DTL which uses a transistor along with diodes. As a transistor can act as an inverter, NAND (NOT-AND) & NOR (NOT-OR) operations can be performed. But this logic uses several diodes which will slow down its operation. Due to the delay offered by them, the logic levels may sometimes change i. e. 0 t0 1 or 1 to 0. Then came TTL. This logic uses a multi emitter transistor, a transistor with many emitter terminals. As every emitter is nothing but a diode, this logic eliminates the use of all diodes. This is the major advantage. As transistor becomes ON and OFF much rapidly than a diode, switching time will be faster.TTL, or Transistor-transistor logic replaced resistor-transistor logic, and used much less power. The TTL family is very fast and reliable, and newer faster, less power-consuming, etc. types are always being developed.ANSWER: ONE WORD SPEED
Why diode logic cannot perform a NOT function?
Diode logic cannot perform a NOT function because diodes only allow current to flow in one direction, which prevents them from creating a true inversion of the input signal. In a NOT gate, the output must be the opposite of the input; for instance, if the input is high (1), the output should be low (0), and vice versa. However, in diode logic, when the input is high, the diode conducts, leading to an output that is also high, failing to achieve the desired inversion. Thus, diode logic is limited to implementing basic AND and OR functions but cannot produce a NOT operation.
When did Operation Logic Bomb happen?
Operation Logic Bomb happened in 1993.
What is logic operation and arithmetic operation?
A logic operation is when you work with the truth or falsehood of statements whereas an arithmetic operation is concerned only with numerical values.
When was Operation Logic Bomb created?
Operation Logic Bomb was created on 1993-04-23.
First computer to use all-diode logic?
a black guy
What are the characteristics of Diode transistor logic?
relatively large propagation delay.
Ability to perform certain logic operation?
The Logical operator has the ability to perform certain logic operations on its input. This is used in Boolean algebra.
What is an AND gate?
An AND gate is a logic gate performing a Boolean logic AND operation.
Why not use and symbol in string function?
You shouldn't use it because it is not and gate in diode logic.
Why some of the logic circuit required another gates to construct the operation?
Because not all the logic gate have what the circuit needs to complete the operation
What are the application of shottky barrier diode?
mostly high speed switches in digital logic circuits
What are the diode logic gate?
A logic gate composed only of diodes and resistors. The only types are AND gates and OR gates. However the number of layers of logic that can be implemented are severely limited due to losses in these gates.
