Hi,
I am using SN74LVC1G74RSE in my board and I have some questions that I don't find the answer in the datasheet:
1. When I turn on the device, with the next inputs:
PRE_N = 'H'
CLR_N = 'H'
D = 'H'
CLK = 'L'
The output is 'H' (Q = 'H'), is that according to the spec ?
if D = 'L'/'X', the output is 'L' (Q = 'L')
2. CLR_N and PRE_N, working on rising (0->1) or falling (1->0) edge ?
My test (on CLR_N) shows that its working on falling edge, is that right ?
3. what is the meaning of Positive-Edge-Triggered ? rising (0->1) or falling (1->0) edge ?
thanks
