Analog Switches, Multiplexers, Demultiplexers Procurement Notes

This specific part number, HEF4051BTS,118, is officially listed as obsolete and no longer manufactured by Nexperia. Procurement efforts should focus on verifying the authenticity of remaining stock from authorized distributors. Engineers must confirm that any available units are genuine components and not counterfeit replacements before integration into production designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Designers requiring this functionality should consider the active successor variant, HEF4051BTT,118, which maintains similar specifications but utilizes a TSSOP-16 package. Alternatively, the automotive-grade HEF4051BT-Q100,118 offers extended temperature ranges up to +125 C and AEC-Q100 qualification. Selection depends on package preference and environmental operating requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

The HEF4051B series belongs to Nexperia's standard CMOS logic family, specifically designed for analog switching applications. This component represents the SSOP package version of the widely used HEF4051 multiplexer. It serves as a foundational building block for creating complex analog signal routing networks within electronic circuits.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The HEF4051BTT,118 is the direct package alternative using TSSOP-16. For automotive applications, the HEF4051BT-Q100,118 provides AEC-Q100 qualification. Cross-reference with other manufacturers' 4051-compatible parts if pinout compatibility is required.
