Flip Flops Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status through current datasheets as regulatory requirements may evolve. Ensure the sourcing channel provides authentic components from authorized distributors to avoid counterfeit risks. Cross-reference the part number with the latest obsolescence notices to assess long-term availability and lifecycle status.

Flip Flops Selection Notes

Select this component when designing systems requiring octal storage with low-voltage compatibility between 2V and 3.6V. The LCX series offers improved performance over older technologies while maintaining pin compatibility. Consider the 20-SOEIAJ package dimensions for PCB layout constraints. Evaluate the 9.5 ns propagation delay against system timing requirements to ensure signal integrity at intended clock frequencies.

Flip Flops Part Context

This device is part of the 74LCX series, which utilizes CMOS technology optimized for low voltage operation. The LCX family bridges the gap between LVC and LVX technologies, offering faster switching speeds than LVC devices. The octal configuration allows for efficient handling of wide data buses in compact form factors suitable for portable and battery-powered electronic devices.
