Procurement Notes
Verify the specific package type and pin configuration against official datasheets before procurement. Ensure that the 3.6V tolerance specifications align with your system's voltage levels. Confirm RoHS compliance status and moisture sensitivity等级 requirements for your manufacturing process. Cross-reference the manufacturer part number to avoid confusion with similar variants in the VCX series.
Selection Notes
Select this component when designing systems requiring 16-bit parallel data storage with mixed-voltage capabilities. The 3.6V tolerance allows direct interfacing between 3.3V and lower voltage logic domains without additional level shifters. Consider the LFBGA package for space-constrained PCB layouts. Evaluate thermal performance and pin count suitability for your specific application density requirements.
Part Context
The 74VCX16374GX belongs to Fairchild's VCX series of low-voltage CMOS logic devices. This series focuses on providing robust performance in mixed-voltage environments. The 16-bit architecture distinguishes it from smaller bit-width counterparts, offering higher data throughput capacity. As part of the broader logic family, it shares design principles with other VCX components but offers specific pinout and functionality tailored for complex bus applications.
Replacement Considerations
Public confirmed substitute part numbers include 74VCX16374. Verify functional equivalence regarding pinout and electrical characteristics before substitution.
