Part Number: CD74AC14
CD74AC14 mentions that it can:
" Operate With Much Slower Than Standard Input Rise and Fall Slew Rates "
What is max dT/dV for any of its Input in terms of nS per Volt?
I am not able to locate in the Data Sheet, please.
Schmitt-trigger inputs do not have an upper limit on the rise/fall time.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Clemens Ladisch:
Many thanx for your quick reply.
Is the above Stt universally valid across the spectrum of
Schmitt Triggers including 74AC14 & 74LVC family?
Someone from TI had informed me in the past that only
CD40106 was well suited to accept slow-moving Inputs.
If I were to feed a 0-5 V Ramp to say 74LVC2G14, what is
peak Input current could I expect?
Thanks and regards
In reply to Varunesh Kumar:
This is true for Schmitt-trigger devices (74xx14/17/97 etc.) in all logic families.
CD4000 and CD74HC are different families.
CMOS inputs always have high impedance; the input current does not increase. However, for input voltages that are not near the rails, the supply current increases. The curve looks similar to the ones shown here, but I have not been able to find this information for the LVC family.
Many thanks for your quick replies.
