Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix MX against the manufacturer's official datasheet to confirm the SOIC-16 package variant. Confirm RoHS compliance status through the latest environmental declaration documents provided by onsemi. Ensure the ordering part number matches the required tape and reel specifications for automated assembly processes.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when dual independent decoding functions are required within a single package footprint. The 74VHC series offers faster switching speeds compared to standard HC logic while maintaining lower power dissipation than AC series devices. Verify that the 2 V to 5.5 V operating range aligns with the target system's power supply rails.

Signal Switches, Multiplexers, Decoders Part Context

This component is part of the broader 74VHC139 product family, which includes variants such as the 74VHC139MTCX and MC74VHC139DR2G. These parts share identical logical functionality but differ in packaging styles and manufacturing lot configurations. The 74VHC139MX specifically denotes the SOIC-16 surface-mount version distributed by onsemi.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Cross-reference with MC74VHC139DR2G for equivalent functional performance in alternative packaging formats. Verify pinout compatibility before substituting with other 74VHC139 derivatives to ensure correct signal routing.
