Buffers, Drivers, Receivers, Transceivers Applications

• Microprocessor input or output port interfaces
• Bus-oriented data storage systems
• High-speed low-power digital logic circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number includes the suffix 'G' for RoHS compliance, as standard listings often reference MC74AC564DWR2G. Confirm the SOIC-20 package type matches your PCB footprint requirements. Ensure moisture sensitivity level (MSL) handling procedures are followed during assembly to prevent damage during soldering processes.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when inverted octal latching functionality is required alongside three-state bus driving capabilities. It serves as the functional inverse of the MC74AC574 series while maintaining identical electrical performance characteristics. Consider the specific pinout arrangement where inputs and outputs are on opposite sides for optimal layout efficiency in dense designs.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the AC series of CMOS logic components produced by onsemi. It is functionally identical to the MC74AC574 but provides inverted outputs. The family is characterized by high speed and low power consumption, suitable for various general-purpose digital applications requiring reliable data storage and transfer.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The MC74AC574DWR2G is the non-inverted equivalent within the same series. For inverted outputs with TTL-compatible inputs, consider the MC74ACT564DWR2G variant.
