Procurement Notes

Verify that the specific part number matches the manufacturer's official documentation for the 74VHC175MX variant. Confirm package type compatibility with design constraints. Ensure compliance with relevant environmental standards such as RoHS requirements before integration. Cross-reference datasheet specifications against system operational limits to guarantee reliable performance under intended operating conditions.

Selection Notes

Select this component when an octal storage solution with high-speed operation is required. The 74VHC series offers speed comparable to bipolar Schottky TTL while maintaining CMOS low power dissipation. Consider the 20-TSSOP package for surface-mount applications requiring compact footprint. Evaluate the 2V to 5.5V supply range against available power rails in the target design environment.

Part Context

This component is part of the broader 74VHC logic family, designed for advanced high-speed CMOS applications. It provides pin and function compatibility with related devices in the series. The 74VHC175 specifically addresses needs for multi-bit synchronous data storage. It is manufactured using silicon gate CMOS technology to achieve high noise immunity and low power consumption characteristics typical of the VHC standard.

Replacement Considerations

The 74VHC175MTCX serves as a verified substitute part number for this component. Both variants belong to the same logical family and share identical functional specifications. When substituting, verify package dimension compatibility between the SOIC and TSSOP form factors if physical space is constrained.
