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.
