Dear,
I do not understand around TR and tf.
1.why need input ,I think ”input“ is unnecessary
2.why Tr,Tf have a max value. for example:
if vdd is 3.3V ,tr max is 10ns/V from datasheet ,in this condition.if input signal rise and fall time (up to 1us/V) is very long ,in this case ,I have two question as follow：
1.actually,tr and tf of input signal is far beyond 10ns/V from datasheet,what will happen ？
2.what is tr and tf of output signal？I want to know what is the meaning of tr max existence?
Thanks!
