Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific suffix 'MTDX' matches the required tape-and-reel packaging configuration. Ensure compliance with RoHS standards and check for any obsolescence notices, as this component may be subject to lifecycle changes. Validate pinout compatibility against the official datasheet before integration into existing designs.
Selection Notes
Select this component for designs requiring 16-bit parallel data latching with low power consumption. The ALVC series offers superior speed compared to standard CMOS logic while maintaining compatibility with 3.3V and lower voltage domains. Consider the 48-TFSOP package dimensions for PCB layout constraints and ensure adequate thermal management for the specified operating temperature range.
Part Context
This device belongs to the Fairchild Semiconductor 74ALVC family, designed for advanced low-voltage CMOS applications. The 74ALVC16374 variant specifically addresses the need for high-density, high-speed data storage in portable and battery-powered devices. It represents a transition point in the company's product line following industry consolidations.
Replacement Considerations
Public confirmed substitute part numbers include SN74ALVCH162374GR and SN74ALVCH16374DGGR from Texas Instruments. Verify functional equivalence and pinout compatibility before substitution.
