Other Parts Discussed in Thread: SN74HCS74-Q1
Posting on behalf of Balazs Kelenvolgyi:
A customer asked me why the input transition rise or fall rate is defined so short (5nS) in the datasheet of SN74LVC2G74QDCURQ1? They want to filter the input with an RC filter and they want to size the filter in a way to have the filtering maximized but still fulfil the minimum slew rate. They successfully tested the device with much slower slew rates e.g.: 100nS/V (ok it was only tested at room temp and this was tried on 1 sample only).
Is it possible to get more background about this parameter? (maybe it can be slower if supply voltage is 5V or 3v3 …I am looking for such dependences if there is any).
It is also a question what happens if they do not fulfil the 5nS/V requirement?
