Re: Trying to bring back a AA501


It appears to me that the MM74C175N has a VCC (max. operating) of 15V and the 74HC175N VCC operating range is -.5V - 7.0V. Otherwise they appear to be similar. Both operate at TTL levels. Quad Flip Flops with common clock and clear to all 4. As long as your operating VCC was compatible, it looks like the 74HC175N could sub in.
