The SN54 / 74LS273 is an 8-Bit Parallel Register with a mon Clock and mon 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.
