• General-purpose parallel-to-serial data storage

Latches Procurement Notes

This component is officially listed as obsolete and no longer manufactured by Nexperia. Procurement should focus on verified surplus stock or authorized distributors holding remaining inventory. Verify part authenticity and condition carefully due to end-of-life status. Consider functional equivalents from the same manufacturer or other vendors if long-term supply stability is required for production.

Latches Selection Notes

Select this component only when legacy compatibility with existing 74HC logic designs is mandatory. Ensure the 20-SSOP package fits the target PCB footprint. Verify that the 2V to 6V operating range aligns with the system power supply. Since the part is obsolete, evaluate alternative sources or substitute parts to mitigate supply chain risks for future manufacturing phases.

Latches Part Context

The 74HC373 series represents a standard family of octal transparent latches widely used in digital electronics. The 'HC' designation indicates High-speed CMOS technology, offering faster switching speeds compared to older LS variants while maintaining low power consumption. This specific variant includes tri-state control for efficient bus management in complex digital architectures.
