Latches Procurement Notes

Verify the specific ordering code suffix 'MTCX' corresponds to the 20-Lead Thin Shrink Small Outline Package (TSSOP) configuration. Confirm that the component is sourced as Tape and Reel packaging. Ensure compatibility with the 4.5V to 5.5V supply voltage requirements and check for any specific environmental compliance documentation required for the project.

Latches Selection Notes

Select this component when an octal latch with 3-STATE outputs is required for bus-oriented systems. It is suitable for designs needing reduced simultaneous switching noise and enhanced dynamic threshold performance compared to standard logic families. Consider the TSSOP-20 package constraints and the 4.5V to 5.5V operating voltage range during circuit planning.

Latches Part Context

This part belongs to the 74ACTQ series of Quiet Series logic devices. It serves as the inverted version of the ACTQ373. The series is characterized by its use of Fairchild's proprietary technology to minimize noise and improve signal integrity in high-speed digital applications.

Latches Replacement Considerations

The datasheet identifies the 74ACTQ373 as the non-inverted counterpart. Verify pin-to-pin compatibility if substituting between these variants. No other direct substitute part numbers are explicitly confirmed in the provided documentation.
