74ACTQ573MTCX

Latches Overview

The onsemi 74ACTQ573MTCX is an octal D-type latch featuring buffered Latch Enable (LE) and Output Enable (OE) inputs. It utilizes FACT Quiet Series technology for improved dynamic threshold performance and simultaneous switching noise control. The device operates at a supply voltage of 4.5V to 5.5V with outputs capable of sourcing or sinking 24 mA. It is housed in a 20-lead Thin Shrink Small Outline Package (TSSOP).

Latches Feature Summary

• Utilizes FACT Quiet Series technology including GTO output control and undershoot correction.
• Features inputs and outputs on opposite sides of the package for easy microprocessor interfacing.
• Provides guaranteed pin-to-pin skew AC performance.
• Offers improved latch-up immunity.

Latches Applications

• Microprocessor interface systems
• Bus-oriented data storage
• High-speed digital logic circuits

Latches Procurement Notes

Verify that the ordering code includes the 'X' suffix to confirm tape and reel packaging, as standard codes may indicate tube packaging. Ensure the component matches the MTC20 package number for the TSSOP form factor. Confirm RoHS compliance status through official manufacturer documentation before integration into production designs.

Latches Selection Notes

Select this component when high-speed octal latching with 3-state outputs is required in a compact surface-mount footprint. The ACTQ variant is suitable for 5V logic systems requiring robust noise immunity. Consider the specific package dimensions of the TSSOP against available board space constraints during the design phase.

Latches Part Context

This part belongs to the 74ACQ/ACTQ family of octal latches. It is functionally identical to the ACQ/ACTQ373 but features inputs and outputs on opposite sides of the package. The series employs Fairchild's Quiet Series technology to ensure quiet output switching and superior dynamic threshold performance compared to standard logic families.
