MC74ACT564N

Flip Flops Overview

The MC74ACT564N is an octal D-type latch manufactured by onsemi, featuring inverted outputs and a common Output Enable (OE) control. It operates within a supply voltage range of 2.0 V to 6.0 V and supports data storage via LOW-to-HIGH Clock transitions. The device provides three-state outputs capable of sourcing or sinking 24 mA, suitable for bus-oriented applications. It is housed in a 20-lead Plastic Dual In-line Package (PDIP-20) with inputs and outputs positioned on opposite sides of the package to facilitate microprocessor port interfacing.

Flip Flops Feature Summary

• Octal D-type latch architecture with inverted outputs
• Common Output Enable (OE) control for bus management
• Three-state outputs supporting high drive current
• Opposite-side pin configuration for easy PCB routing

Flip Flops Applications

• Bus-oriented data storage systems
• Microprocessor input/output port interfaces
• High-speed digital signal latching
• Parallel data transfer applications

Flip Flops Procurement Notes

Verify component authenticity through official onsemi channels or authorized distributors. Confirm that the PDIP-20 package matches design requirements. Ensure the operating temperature range aligns with system specifications. Check for RoHS compliance status if environmental regulations apply. Validate datasheet revisions to ensure functional compatibility with existing designs.

Flip Flops Selection Notes

Select this component when inverted octal latching is required for bus applications. Compare with non-inverting variants like MC74AC574 if output polarity differs from design needs. Consider the ACT series speed and power characteristics relative to standard AC logic. Verify package availability and lead times for production planning. Assess thermal performance within the specified operating temperature range.

Flip Flops Part Context

This part belongs to the 74ACT family of high-speed CMOS logic devices. It is functionally identical to the MC74AC574 but features inverted outputs instead of non-inverted ones. The device complements other octal buffers and latches in the onsemi portfolio, providing versatile options for digital logic design requiring specific output polarities and bus driving capabilities.

Flip Flops FAQ

What is the relationship between MC74ACT564N and MC74AC574?

They are functionally identical except that the MC74ACT564N has inverted outputs while the MC74AC574 has non-inverted outputs.

How does the Output Enable (OE) control work?

A common OE signal controls all eight outputs simultaneously, allowing them to be placed in a high-impedance state for bus-oriented applications.
