X74_273 is an 8-bit data register with active-low asynchronous clear. The active-Low asynchronous clear (CLR), when Low, overrides all other inputs and resets the data outputs (Q8 - Q1) Low. When CLR is High, the data on the data inputs (D8 - D1) is transferred to the corresponding data outputs (Q8 - Q1) during the Low-to-High clock transition (CK).
