Overview
74HC574; 74HCT574 Octal D-type flip-flop; positive edge-trigger; 3-state Rev.
7 — 4 March 2016 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 VCC.
