MC74HCT573ADWG

Latches Overview

The MC74HCT573ADWG is an octal transparent latch manufactured by onsemi, belonging to the HCT logic series. It features eight non-inverting D-type latches with three-state outputs housed in a 20-pin SOIC-Wide package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum propagation delay of 30 ns at 5 V. It exhibits low static current consumption of 4 uA and provides robust output drive capabilities, including a low-level output current of 32 mA and a high-level output current of -6 mA. The component is rated for operation across an extended temperature range from -55 C to +125 C.

Latches Feature Summary

Latches Procurement Notes

Verify the specific suffix 'ADWG' corresponds to the SOIC-Wide package and tube packaging configuration as listed in official distributor catalogs. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target design to avoid compatibility issues with similar variants.

Latches Selection Notes

Select this component when designing systems requiring octal data latching with high-speed performance and strong drive capability. The HCT series ensures compatibility with standard TTL logic families, simplifying interface design. Consider the wide operating temperature range if the application involves extreme environmental conditions. Verify that the package dimensions fit the available PCB space constraints before finalizing the design.

Latches Part Context

This part belongs to the MC74HCT573A family of octal transparent latches. It serves as a digital storage element within the broader 74HCT logic product line. The device is designed to replace older NMOS technologies while maintaining pin compatibility and logical function. It is commonly used in conjunction with other HCT series components to build complex digital logic systems requiring reliable data retention and transfer.

Latches Replacement Considerations

Public confirmed substitute part numbers include MC74HCT573ADTR2G for tape-and-reel packaging variants.
