Procurement Notes

Verify the specific suffix 'MEA' against the official datasheet to confirm package type and tape/reel specifications. Ensure the revision level matches your design requirements. Confirm RoHS compliance status through the manufacturer's latest documentation. Check for any obsolescence notices or lifecycle changes before finalizing procurement plans.

Selection Notes

Select this component when designing circuits that require 16-bit buffering with individual nibble control. It is suitable for applications needing high-speed signal integrity within a 2.0 V to 3.6 V supply range. Consider the 48-SSOP package constraints for PCB layout. Verify input/output voltage compatibility with connected logic families.

Part Context

This part belongs to the 74LCX series, which utilizes advanced CMOS technology for low voltage operation. It serves as a digital logic buffer within the broader family of interface components. The LCX series is designed to replace older HC/HCT devices in modern low-power designs. It offers improved performance characteristics compared to standard TTL equivalents.

Replacement Considerations

Check for direct pin-compatible alternatives within the same logic family. Verify electrical parameters such as propagation delay and output current against original requirements. Ensure package dimensions match existing footprints. Consult official substitution guides for validated cross-references.
