My question is if value vary from manufacture then its value should be unknown, why it is not acceptable? If in any IC value matches then what?

There is something called strong 0 and weak 1. Could that be related here, because a voltage near to 5V say 4.8V is treated as strong 1.

0 to 1.5 logic 0.
1.5 to 3.5 is unacceptable.
3.5 to 5 logic 1.

If the value of voltages lies between 2 to 3 is known as unacceptable.

But in digital systems 0 to 1.5V is treated as logic 0 & 3.5V to 5V treated as logic 1.

So that why it is unacceptable.

Karthik said: 1 decade ago

Exactly as jigar said IC's vary from manufacture to manufacture.

And the values of V_L and V_H vary.

Poonam said: 1 decade ago

Am also agree with niranjan because in digital voltage in b/w 1. 5v to 3. 5v is unvaluable thats why it is unacceptable.

I think in digital by quantization.

We make that level of supply according to our device.

Generally its 0/5 volt.

Vaidehi said: 7 years ago

Since it is digital that's why no varying value is acceptable thus answer is unacceptable for digital circuits.

BHARGAV said: 1 decade ago

I think that the values are not necessary as the circuit operates for either max or min with acceptable errors.

Voltage between vl and vh is not acceptable because the IC property is vary from one manufacturer to other.
