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.
Feature Summary
- CMOS technology providing low power dissipation and high noise immunity
- Integrated clamp diodes on inputs for interfacing with voltages exceeding VCC
- ESD protection compliant with JEDEC standards, exceeding 2000 V HBM and 1000 V CDM
- Fully static operation capability
Applications
- Analog multiplexing and demultiplexing
- Digital multiplexing and demultiplexing
- Signal gating
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.
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.
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.
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.
