Procurement Notes

This component is officially obsolete and no longer manufactured by NXP USA Inc. Procurement should focus on verified substitute part numbers listed in replacement considerations. Verify that alternative sources provide genuine components, as availability is limited to existing stock or cross-manufacturer equivalents. Ensure compatibility with existing design specifications before sourcing substitutes.

Selection Notes

Select this component only if legacy support for the LVT series is required. Consider the 3.3 V operating voltage constraint and the specific current drive capabilities when designing power supplies. Evaluate thermal performance within the specified temperature range. Review pinout compatibility if replacing with similar devices from other manufacturers.

Part Context

The 74LVT574PW,118 belongs to the Low Voltage TTL (LVT) logic family, designed for 3.3 V applications. It is part of the broader 74xx series of digital logic integrated circuits. The TSSOP-20 package provides a compact surface-mount solution suitable for space-constrained designs. This specific variant represents a standard octal flip-flop configuration widely used in historical digital electronics.
