Additional Details

The TC74AC175F(ELF) is supplied in a SOP16 package. It operates over a wide temperature range, typically -40°C to +85°C. Each flip-flop is edge-triggered and changes state on the positive-going transition of the clock input. The direct clear input overrides all other inputs and sets the Q output low.
