Nexperia 74HC574PW,118 D Type Flip Flop IC, 3-State, 20-Pin TSSOP
Product DetailsThe 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.
Mixed 5 V and 3.3 V applications
Improved signal integrity with integrated termination resistors
High noise immunity
Flow through pin out for easy layout
Wide supply voltage range
Low propagation delay
Overvoltage tolerant input options
Integrated source termination resistor options
Bus hold options
Frequency division
Controlled delays
Interface between asynchronous and synchronous systems
