Procurement Notes

Verify the specific suffix AQ20-13 against official Diodes Incorporated documentation to confirm the QFN-20 package variant and automotive-grade qualification status. Ensure compatibility with target PCB footprint dimensions and thermal requirements before finalizing procurement orders.

Selection Notes

Select this component when designing low-voltage logic circuits requiring octal storage with tri-state outputs. Consider the 3.8 ns propagation delay and 24 mA drive strength for timing and load analysis. Verify that the operating temperature range meets environmental constraints and that the QFN-20 package aligns with assembly capabilities.

Part Context

This part belongs to the 74LVC series of low-voltage CMOS logic devices produced by Diodes Incorporated. The LVC family provides performance improvements over standard CMOS while maintaining pin compatibility with legacy 74-series logic. The 374 designation specifically indicates an octal D-type flip-flop function within this logic family.

Replacement Considerations

Cross-reference equivalent parts such as the 74LVC374AT20-13 for TSSOP-20 package alternatives or other manufacturers' 74LVC374 variants. Confirm electrical parameters, pinout compatibility, and package dimensions match system requirements before substitution.
