Overview
The MC74HC4851ADWR2 is an analog multiplexer/demultiplexer from the onsemi 74HC series, housed in a 16-SOIC surface-mount package. It functions as an 8-to-1 switch with a single circuit configuration. The device operates within a supply voltage range of 2V to 6V and supports an operating temperature range from -55°C to +125°C. Key electrical specifications include a maximum on-resistance of 400 ohms, channel capacitance of 40pF, and maximum leakage current of 100nA. The component is classified under interface ICs for analog switching applications.
Feature Summary
- Provides 8-to-1 signal routing capability through a single multiplexer circuit
- Operates across a wide industrial temperature range for robust environmental performance
- Features low off-state leakage current to maintain signal integrity when inactive
Applications
- Data acquisition systems requiring multi-channel signal selection
- Industrial control interfaces for sensor data routing
- Communication equipment utilizing analog signal path switching
Procurement Notes
Verify RoHS compliance status carefully, as specific listings indicate non-compliance for this suffix variant. Confirm the exact package width and lead form against design constraints. Ensure the supplier documentation matches the MC74HC4851ADWR2 designation precisely to avoid confusion with tape-and-reel versions or green variants.
Selection Notes
Select this component when a wide operating temperature range and 16-pin SOIC footprint are required. Compare on-resistance values if signal attenuation is critical. Verify that the 2V to 6V supply range aligns with system power rails. Consider alternative packages like TSSOP if board space is limited.
Part Context
This part belongs to the 74HC4851 family of high-speed CMOS logic devices. It shares functional similarities with the MC74HC4852ADR2G but differs in channel count and pinout. The ADWR2 suffix denotes a specific commercial-grade packaging and manufacturing lot configuration distinct from automotive or green-certified variants.
Replacement Considerations
MC74HC4851ADR2G serves as a direct functional substitute with identical electrical characteristics. Verify package compatibility between SOIC and tape-reel formats before substitution.
