... Functional Description The DM74LS273 is an 8-bit parallel register with a common Clock and common Master Reset. When the MR input is LOW, the Q outputs are LOW, independent of the other inputs. Information meeting the setup and hold time requirements of the D inputs is transferred to the Q outputs on the LOW-to-HIGH transition of the clock input. ...
