Procurement Notes

Verify component authenticity as this specific part number is marked as obsolete and no longer manufactured. Confirm that any available units are genuine surplus or verify if an approved replacement from onsemi is required for new designs. Ensure the package type matches the target PCB footprint before procurement.

Selection Notes

Select this component when a dual-channel 16-bit transceiver is required for low-voltage applications. Consider the 54-FBGA package constraints during layout. Evaluate alternative packages like MTDX if surface area is limited or if lead-free soldering processes require specific thermal profiles different from the original FBGA specification.

Part Context

This component belongs to the 74LCX series, designed for high-speed, low-power CMOS applications. It serves as a bridge between different logic families, facilitating data movement in complex electronic architectures where multiple voltage domains interact.
