Overview
The NLVHC4851ADWR2G is a high-speed CMOS octal differential multiplexer/demultiplexer manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 6.0 V and features low static power consumption. The device utilizes a 16-SOIC surface-mount package with a width of 7.50 mm. It supports automotive-grade reliability standards, ensuring functionality across an extended temperature range from -40°C to +125°C. The component integrates three address inputs to select one of eight data channels, facilitating efficient signal routing in complex electronic systems.
Feature Summary
- Automotive-grade qualification for enhanced reliability in vehicle electronics
- High-speed switching capability supporting fast data transmission rates
- Low power consumption design suitable for battery-operated applications
Applications
- Automotive infotainment system signal routing
- Data acquisition systems requiring multi-channel selection
- Industrial control interfaces for sensor data multiplexing
Procurement Notes
Verify the specific suffix 'G' indicates RoHS compliance and green manufacturing status as per onsemi standards. Confirm the automotive grade designation aligns with AEC-Q100 requirements if specified in the official datasheet. Ensure the 16-SOIC package dimensions match your PCB footprint constraints. Check for any specific storage or handling instructions related to moisture sensitivity level classification provided in the manufacturer's documentation.
Selection Notes
Select this component when automotive reliability and wide operating temperature ranges are required. Compare performance metrics such as propagation delay and ON-resistance against standard commercial grade alternatives if cost is a primary constraint. Ensure the input logic levels are compatible with the driving circuitry within the 2.0 V to 6.0 V supply range. Verify that the pinout configuration matches existing board designs to avoid redesign efforts.
Part Context
This part belongs to the NLVHC series, which represents the automotive-qualified extension of the standard 74HC logic family. While sharing functional similarities with the MC74HC4851ADWR2, the NLV variant specifically targets applications demanding higher reliability and stricter environmental testing protocols. It serves as a specialized solution for industries where failure tolerance is critical, distinguishing it from general-purpose industrial components.
Replacement Considerations
Direct substitutes include other automotive-qualified 8:1 multiplexers from onsemi or competitors meeting identical pinout and electrical specifications. Verify compatibility with existing control logic and ensure thermal management requirements are met. Cross-reference package dimensions to confirm mechanical interchangeability without PCB modifications.
