Overview
The SE81NLV74HC4851ADTR2G is an analog multiplexer/demultiplexer manufactured by onsemi. It belongs to the LV74HC4851 series, designed for signal routing applications. The component operates within a supply voltage range of 2 V to 6 V and supports surface mount installation. It features injection current effect control to maintain signal integrity during switching operations. The device is housed in a 16-TSSOP package with dimensions of 0.173 inches (4.40 mm) width. It functions as a single circuit 8:1 mux/demux with a maximum on-resistance of 400 ohms. The operational temperature range spans from -55°C to +125°C.
Feature Summary
- Integrates injection current effect control for improved signal fidelity
- Supports wide supply voltage operation from 2 V to 6 V
- Provides 8-to-1 analog multiplexing or demultiplexing functionality
- Designed for high-temperature industrial environments up to 125°C
Applications
- Signal routing in data acquisition systems
- Analog signal switching in instrumentation equipment
- Multiplexing channels in communication interfaces
- Data selection in embedded control circuits
Procurement Notes
Verify that the specific suffix 'SE81NLV' aligns with your design requirements, as it denotes a variant within the LV74HC4851 family. Confirm package compatibility with your PCB footprint, specifically the 16-TSSOP form factor. Ensure the operating voltage and temperature ranges meet your system specifications. Check for end-of-life status if long-term production stability is required. Cross-reference datasheet parameters against your application constraints before finalizing procurement.
Selection Notes
Select this component when requiring an 8-channel analog switch with controlled injection currents. Consider the 400-ohm on-resistance limit for signal path losses. Evaluate the 16-TSSOP package size against available board space. Verify that the 2 V to 6 V supply range matches your power architecture. Assess thermal performance within the -55°C to +125°C operational window for environmental suitability.
Part Context
This part is part of the broader 74HC4851 logic family, which includes variants like MC74HC4851ADWR2G and MC74HC4851ADTR2G. These components share similar functional architectures but may differ in packaging, speed, or specific electrical characteristics. The SE81NLV prefix indicates a specific sub-type or revision within the LV74HC4851 line, distinguishing it from standard HC series parts.
Replacement Considerations
Direct substitutes include MC74HC4851ADTR2G and MC74HC4851ADWR2G from onsemi, provided pinout and electrical parameters are compatible. Verify that alternative packages match the physical constraints of the existing design. Ensure that any replacement maintains the required injection current control and voltage operating ranges.
