Overview
The NLV74HC4851AMNTWG is a single-channel 8-to-1 analog multiplexer/demultiplexer manufactured by onsemi. It operates within a supply voltage range of 2V to 6V and features a maximum on-resistance of 400 ohms. The device supports an operating temperature range from -55°C to +125°C and meets AEC-Q100 automotive qualification standards. Key electrical specifications include a maximum leakage current of 100nA and channel capacitance of 40pF. It is housed in a 16-VFQFN package with dimensions of 2.5x3.5mm, designed for surface mount installation.
Feature Summary
- Automotive-grade reliability certified under AEC-Q100 standards
- Wide operating temperature range suitable for harsh environments
- Compact 16-pin QFN footprint for space-constrained designs
Applications
- Automotive sensor signal routing
- Data acquisition systems requiring analog switching
- Industrial control interface multiplexing
Procurement Notes
This component has been officially discontinued as per Product Change Notice OBS dated August 22, 2023. Availability is limited to existing stock or third-party distributors. Verification of authenticity and lot traceability is critical due to the end-of-life status. Buyers should confirm the specific revision level and ensure compliance with RoHS3 requirements before finalizing procurement decisions.
Selection Notes
Designers should consider the 400-ohm maximum on-resistance when selecting this part for low-voltage signal paths. The 2V minimum supply voltage allows compatibility with lower power logic families. Ensure the PCB layout accommodates the 16-QFN exposed pad thermal requirements. Verify that the 40pF channel capacitance meets the bandwidth requirements of the target application signals.
Part Context
This part belongs to the NLV series, which denotes automotive-grade variants of the standard 74HC4851 logic family. It shares functional pinouts with the MC74HC4851 but offers enhanced durability and extended temperature ranges required for automotive electronics. The NTWG suffix indicates the specific tape-and-reel packaging configuration.
Replacement Considerations
Direct replacements are limited due to discontinuation. Consider the MC74HC4851ADWR2 for SOIC-16 packages, though it lacks automotive qualification. Generic 74HC4851 equivalents may fit electrically but require verification of temperature ratings and package compatibility.
