HEF4051BP,652

Analog Switches, Multiplexers, Demultiplexers Overview

The HEF4051BP,652 is an 8-channel analog multiplexer/demultiplexer manufactured by Nexperia. It operates as a single-pole octal-throw switch with three digital select inputs (S1-S3), eight independent I/Os (Yn), one common I/O (Z), and an active LOW enable input (E). The device supports a supply voltage range of 3.0 V to 15.0 V. Static characteristics include an OFF-state leakage current of up to 1000 nA at 15 V and a maximum ON resistance of 2500 Ω at 5 V. Dynamic performance features propagation delays up to 300 ns and a -3 dB frequency response reaching 70 MHz at 15 V.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Provides high noise immunity and fully static operation suitable for analog or digital signal routing.
• Includes input clamp diodes allowing interface to voltages exceeding the supply rail using current limiting resistors.
• Offers ESD protection compliant with JEDEC standards, exceeding 2000 V via Human Body Model and 1000 V via Charged Device Model.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix '652' against the manufacturer's official ordering information to confirm the package type and tape-and-reel specifications. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the design accounts for the specified ambient temperature operating range of -40 °C to +125 °C during system integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8:1 switching configuration is required within a 3 V to 15 V supply environment. Consider the peak ON resistance limits at your specific operating voltage to ensure signal integrity. Verify that the total harmonic distortion and isolation levels meet the requirements of the intended analog signal path.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the HEF4051B family of 8-channel analog multiplexers produced by Nexperia. The product data sheet revision 14 was released on July 25, 2024. The BP suffix indicates a plastic DIP package variant, distinct from the SO16 or TSSOP16 packages listed in the ordering table.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same logic family include other HEF4051 variants such as HEF4051BT or HEF4051BTT, provided the package footprint matches the PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the enable input function?

The enable input (E) is active LOW. When E is HIGH, all switches are turned off regardless of the state of the select inputs S1, S2, and S3.

What is the purpose of the input clamp diodes?

The inputs include clamp diodes that allow the use of current-limiting resistors to interface the switch inputs to voltages in excess of the positive supply voltage (VDD).

What is the maximum power dissipation rating?

The total power dissipation (Ptot) is rated at 500 mW over the operating temperature range of -40 °C to +125 °C.
