MC74ACT564DWR2G

Flip Flops Overview

The MC74ACT564DWR2G is an octal D-type latch with inverted outputs, manufactured by onsemi. It operates within a supply voltage range of 4.5 V to 5.5 V and features three-state outputs for bus-oriented applications. The device provides source/sink currents of 24 mA and exhibits a maximum propagation delay of 9 ns at 50 pF load. It is housed in a 20-SOIC package and supports surface-mount installation. The component functions identically to the MC74AC574/74ACT574 but with inverted logic levels.

Flip Flops Feature Summary

• Octal D-type latch configuration with inverted outputs
• Three-state outputs suitable for bus-oriented applications
• Inputs and outputs positioned on opposite sides of the package

Flip Flops Applications

• Microprocessor input or output port interfacing
• Bus-oriented data storage systems
• General-purpose digital logic circuits requiring inverted latching

Flip Flops Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance for related AC series variants. Confirm package dimensions match SOIC-20 specifications. Ensure supply voltage constraints are strictly maintained between 4.5 V and 5.5 V during operation. Check for moisture sensitivity level requirements prior to soldering processes.

Flip Flops Selection Notes

Select this component when inverted octal latching functionality is required alongside three-state bus driving capabilities. It serves as a direct functional alternative to the MC74AC574/74ACT574 series where output inversion is necessary. Consider the 24 mA drive strength and 9 ns delay characteristics for timing-sensitive designs.

Flip Flops Part Context

This part belongs to the 74ACT logic family, designed for high-speed CMOS applications. It is functionally identical to the MC74AC574/74ACT574 but provides inverted outputs. The device is commonly used in microprocessor systems where data latching and bus isolation are critical requirements.
