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
