Procurement Notes
Verify the specific suffix against official documentation, as variations may indicate different packaging or environmental compliance levels. Confirm availability status directly with the manufacturer or authorized distributors, as this component may be subject to discontinuation notices. Ensure that the procurement channel provides valid traceability and authenticity guarantees for integrated circuits.
Selection Notes
Select this component when high-speed switching and moderate drive strength are required within a compact surface-mount footprint. Compare against HC series variants if lower speed is acceptable, or ACT series if CMOS compatibility with TTL inputs is necessary. Verify that the 20-TSSOP package dimensions fit the target PCB layout constraints and thermal requirements.
Part Context
This part belongs to the widely adopted 74AC family of high-speed CMOS logic devices. It serves as a standard solution for parallel data storage and buffering in digital systems.
