Overview
The MC74HC4851ADR2G is a single-channel analog multiplexer/demultiplexer manufactured by onsemi. It operates within a supply voltage range of 2V to 6V and utilizes a 16-SOIC surface-mount package with a width of 3.90mm. The device provides an 8:1 multiplexing configuration, featuring a maximum on-resistance of 400 ohms and a channel capacitance of 40pF. Maximum leakage current is specified at 100nA. It supports an operating temperature range from -55°C to +125°C and complies with RoHS3 standards.
Feature Summary
- Provides 8-to-1 analog signal routing capability for data acquisition systems
- Operates across a wide supply voltage range suitable for low-voltage logic interfaces
- Includes injection current effect control to maintain signal integrity during disabled states
Applications
- Data acquisition systems requiring multi-channel signal selection
- Process control instrumentation for sensor input switching
- Industrial automation equipment utilizing analog signal routing
Procurement Notes
Verify the specific suffix 'ADR2G' against the manufacturer's official datasheet to confirm the SOIC-16 package and tape-and-reel packaging format. Ensure compliance requirements match project specifications, as this variant adheres to RoHS3 standards. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when an 8-channel analog switch is required in a 16-pin surface-mount footprint. The 400-ohm on-resistance and 40pF capacitance define its performance limits for signal fidelity. Verify that the 2V to 6V supply voltage range aligns with the system power rails and that the -55°C to +125°C temperature rating meets environmental constraints.
Part Context
This part belongs to the 74HC4851 family of analog multiplexers produced by onsemi. It serves as a standard CMOS solution for routing multiple analog inputs to a single output line. The device is functionally compatible with other industry-standard 8-channel mux architectures, facilitating design portability across different hardware platforms.
Replacement Considerations
The MC74HC4851ADTR2G offers identical electrical characteristics but utilizes a 16-TSSOP package instead of the SOIC-16 form factor. Other variants within the 74HC4851 series may share pinouts but require verification of package dimensions and thermal performance for direct substitution.
