Procurement Notes

Verify the component authenticity by checking the manufacturer marking against official Texas Instruments documentation. Confirm the specific suffix 'G4' indicates lead-free compliance and RoHS status as per the datasheet. Ensure the package type matches the required 16-SOIC footprint for PCB layout compatibility. Cross-reference the date code and lot number with supplier certificates to guarantee quality standards.

Selection Notes

Select this component when a compact solution for multiple D-type flip-flops is required in space-constrained designs. Consider the 14MHz clock frequency limit for timing-critical applications. Evaluate the 120ns propagation delay against system speed requirements. The wide operating voltage range allows compatibility with various logic levels, while the industrial temperature rating suits harsh environments.

Part Context
