74HC273; 74HCT273

Octal D-type flip-flop with reset; positive-edge trigger

Rev. 7 — 6 September 2021

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 V_CC

2. Features and benefits

•

Wide supply voltage range from 2.0 V to 6.0 V

•

CMOS low power dissipation

High noise immunity

Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
