Yeah that makes sense and looking at the datasheet thats what it implied but wanted to check i understood correctly.

Thanks again. I'm starting my first real project, so will almost certainly be asking more questions  XD

Its a 74HC series logic chip, it behaves like all the other 74HC logic chips - its CMOS so the output is either 0V or Vdd (or if overloaded somewhere inbetween)

The recommended maximum supply is 6V.  7V is an absolute max rating, avoid it.

I'm not sure if someone is confusing 'input' with 'supply'.  The shift register does not shift a voltage level, it shifts a logic state (LOW or HIGH). It specifically is not an analog bucket brigade delay line chip...
