74HC574; 74HCT574

Octal D-type flip-flop; positive edge-trigger; 3-state

Rev. 9 — 20 October 2022

Product data sheet

1. General description

The 74HC574; 74HCT574 is an 8-bit positive-edge triggered D-type flip-flop with 3-state outputs.

The device features a clock (CP) and output enable (OE) inputs. The flip-flops will store the state

of their individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH

clock (CP) transition. A HIGH on OE causes the outputs to assume a high-impedance OFF-state.

Operation of the OE input does not affect the state of the flip-flops. 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
