The SN54 / 74LS273 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. GUARANTEED OPERATING RANGES .
L Unit Load (U.L.) = 40 µA HIGH/1.6 mA LOW. b) The Output LOW drive factor is 2.5 U.L. for Military (54) and 5 U.L. for Commercial (74) Temperature Ranges.
