SN74LVC14APWE4 :-
What is the output rise time / fall time for Vcc=3.3V ?
Any input rise time /fall time requirement for this device?

Also can you suggest any other hex Schmitt trigger part with

Vcc = 3.3V
noninverting outputs
output Tr/Tf better than or equal to 5ns/V
input signal with very low rise and fall times

The rise time depends mostly on the output load. See [FAQ] What is the output transition rate for a logic device?

Schmitt-trigger inputs do not have any rise/fall time requirements.

If you want to have fast rise/fall times on the output, you need a device with strong output drivers. LVC already is the strongest CMOS family, but you can increase the drive strength by using multiple gates in parallel.

Hi Dilip,

Unfortunately, we don't have a hex non-inverting version of this device.
