Procurement Notes

Verify the current production status before procurement, as official sources indicate this specific part number may be obsolete or subject to discontinuation. Confirm package compatibility and lead times with authorized distributors. Ensure the replacement strategy accounts for potential end-of-life constraints associated with legacy logic families.

Selection Notes

Select this component for designs requiring robust bidirectional data transfer across wide voltage domains. The LV series offers optimized performance for low-voltage applications while maintaining compatibility with higher voltage interfaces. Consider the SSOP package dimensions and thermal characteristics when designing the PCB layout for adequate heat dissipation.

Part Context

This part belongs to the 74LV logic family, designed for low-voltage digital applications. It serves as a standard interface solution for connecting microprocessors, memory devices, and peripheral components in mixed-voltage environments. The device provides reliable signal integrity and noise immunity for complex digital circuits.

Replacement Considerations

Check for direct pin-compatible substitutes within the same logic family or updated Nexperia product lines. Verify that alternative components maintain the required voltage range and package type to ensure seamless integration without redesigning the circuit board.
