HEF4051BT,652

Analog Switches, Multiplexers, Demultiplexers Overview

The HEF4051BT,652 is an 8-channel analog multiplexer/demultiplexer manufactured by Nexperia. It operates within a supply voltage range of 3 V to 15 V and features three digital select inputs (S1, S2, S3), eight independent I/Os (Yn), a common I/O (Z), and an active-low enable input (E). The device utilizes SOIC-16 packaging (SOT109-1) with a body width of 3.9 mm. Key electrical parameters include a maximum ON resistance of 2500 Ω at 5 V and 175 Ω at 15 V. Propagation delays reach up to 30 ns, while OFF-state leakage current is specified at 1000 nA at 15 V. The component supports an operating temperature range from -40 °C to +125 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature rating. Confirm that the HEF4051BT variant meets the required thermal specifications for the intended application environment. Ensure compatibility with existing PCB footprints for the SOIC-16 package before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel analog switch is required within a 3 V to 15 V supply range. Consider the peak ON resistance limits at the target supply voltage to ensure signal integrity. Verify that the propagation delay characteristics align with the system timing requirements. Check if the extended industrial temperature range (-40 °C to +125 °C) is necessary for the deployment environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the HEF4051B series of 8-channel analog multiplexers. The 'BT' designation indicates the SOIC-16 plastic small outline package (SOT109-1). Other variants in the family include TSSOP-16 packages. The device is part of Nexperia's standard CMOS logic portfolio, designed for general-purpose switching applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements must match the 8-channel configuration and SOIC-16 package. Verify pinout compatibility, specifically the location of the enable input and common terminal. Ensure equivalent or better ON resistance and propagation delay specifications are met.
