74HC273; 74HCT273 Octal D-type flip-flop with reset; positive-edge trigger Rev. 5 26 February 2016 Product data sheet 1. General description The 74HC273; 74HCT273 is an octal positive-edge triggered D-type flip-flop. The device features clock (CP) and master reset (MR) inputs. The outputs Qn will assume the state of their corresponding Dn inputs that meet the set-up and hold time requirements on the LOW-to-HIGH clock (CP) transition. A LOW on MR forces the outputs LOW independently of clock and data inputs. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. 2. Features and benefits  Input levels:  For 74HC273: CMOS level  For 74HCT273: TTL level  Common clock and master reset  Eight posit [ ... ]
