FUNCTIONAL DESCRIPTION
The SN74LS273 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.
