MC74ACT564DWR2

Flip Flops Overview

The MC74ACT564DWR2 is an octal D-type flip-flop with inverted outputs manufactured by onsemi. It belongs to the 74ACT logic series, designed for high-speed and low-power applications. The device features a single element containing eight bits of storage. It utilizes positive-edge triggering to capture data at the clock input. The component operates within a supply voltage range of 4.5V to 5.5V. It provides three-state outputs suitable for bus-oriented systems. The maximum propagation delay is specified at 11ns under standard test conditions.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with inverted outputs
• Three-state output capability for efficient bus driving
• Positive-edge triggered data storage mechanism
• High-speed CMOS technology ensuring low power consumption

Flip Flops Applications

• Bus-oriented memory interface circuits
• Microprocessor input or output port buffering
• Parallel data latching in digital systems
• Shift register configurations requiring inverted states

Flip Flops Procurement Notes

Verify component authenticity through authorized distribution channels due to potential counterfeit risks. Confirm RoHS compliance status as historical documentation indicates non-compliance for certain manufacturing periods. Check for specific ordering suffixes that may denote package variations or environmental certifications. Ensure compatibility with existing PCB footprints and signal integrity requirements before finalizing procurement decisions.

Flip Flops Selection Notes

Select this component when inverted octal latching functionality is required within a 5V logic environment. Compare against the non-inverted MC74ACT574 variant if output polarity differs from design specifications. Evaluate propagation delay and drive current capabilities against system timing constraints. Consider alternative packages if surface-mount SOIC-20 does not align with assembly processes.

Flip Flops Part Context

This part belongs to the MC74ACT564 family of octal D-type flip-flops. It is functionally identical to the MC74AC564 but optimized for 5V operation with TTL-compatible inputs. The device shares architectural similarities with other members of the 74ACT series, offering improved speed over standard AC logic while maintaining low power characteristics typical of CMOS technology.
