Hi,
With reference to the datasheet link in TI : timing is purely based on external components.
Once fired, the outputs are independent of further transitions…
Part Number: SN74221 Other Parts Discussed in Thread: CD74HCT221 , When I refer SN74221NE4 datasheet, they suggested to consider as ln2.
From the agile we see the part# we are using is SN74221NE4 , referring to the datasheet :
tw(out) = CextRext In2 ≈ 0…
Part Number: SN74221 Hi forum,
Does anyone know what is the width resolution of the pulse generated by SN74221?
I am working on designing a monostable multivibrator which generates the pulses of < 500 ps in the precision of pulse-width. (The range of…
Hello Albert,
Yes, you are spot on with my question, exactly correct point.
Value of resistor is 1%(R56) and Cap(C26) is 2%, that's how the theoretical calculations done.
I did measure those values on board and are within the tolerance spec.
The difference…
Other Parts Discussed in Thread: SN74221 Am using several SN74221 circuits to generate timing waveforms and triggering three of them from the same input pulse. One operates normally but the other ones ignore every other pulse (output is half the rep-rate…
