We are looking at an application that requires doing something not originally intended with one of our designs and for it to work we need to know something that I have not found in the datasheet.
The question is whether the storage registers in the SN74LV595A come up in a known state at power-up. Presumably they do not but it would be helpful if they do (and it is guaranteed.) Normally we initialize the storage registers right after power-up but we have a situation now where we might need to leave them uninitialized for an extended period of time after power-up because the part of the system that initializes them would not be running. Since the hardware that controls the SN74LV595A would not be running we would not be able to force the storage register contents to a known state using the SRCLR# signal.
