- **Wide Operating Voltage Range (2 V to 6 V)**  
- **Fast Switching Speed**  
- **Low Charge Injection**  

This device is commonly used in automotive systems, data acquisition, and communication interfaces.

Application Scenarios & Design Considerations

8-Channel Analog Multiplexer/Demultiplexer with Injection-Current Effect Control

Alternative Part Number

  • CD74HC4051QM96Q1 --: Automotive-qualified 8-channel analog multiplexer/demultiplexer in the same TSSOP package with comparable on-resistance and supply range, making it a strong drop-in functional replacement.
  • MC74HC4051ADTR2G --: Industry-standard 8-channel analog multiplexer with similar Ron and voltage ratings, widely available in TSSOP and commonly used as a cross for HC4051-type parts.
  • 74HC4051PW,118 --: General-purpose 8-channel analog mux/demux in TSSOP with matching logic family characteristics; suitable when automotive qualification is not strictly required.
