SN54SC6T14-SEP: Max input rise time - do we really mean this for the Schmitt trigger?

Hi there,

I see a MAX specification for the input rise time of the Schmitt trigger gate. Do we really mean this?

How would the device behave with in input signal moving at 1.5ms/V?

Thank you for your help in advance.

Sincerely,

Tom

Hello Tom,

1) That's correct. Max 20ns/V for input transition

2) Even with Schmitt trigger inputs, the device will have higher ICC current draw with slow moving signals. This is shown as Delta ICC on the datasheet.

Regards,

Josh
