HD74HC4051FPK

Analog Switches, Multiplexers, Demultiplexers Overview

The HD74HC4051FPK is a single 8-channel analog multiplexer/demultiplexer manufactured by Renesas Electronics Corporation. It belongs to the HC logic series and utilizes CMOS technology. The device operates within a supply voltage range of 2.0 V to 6.0 V. It features an inhibit input terminal that disables all switches when held at a high level. Digital control inputs A, B, and C select one channel out of eight for bidirectional signal transmission. The component is designed for industrial temperature applications, supporting operation from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Provides eight bidirectional analog switches controlled by digital address lines
• Includes an inhibit function to disable all channels simultaneously
• Supports wide operating supply voltage ranges compatible with standard logic levels

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'FPK' against official Renesas documentation to confirm package type and tape/reel specifications. Ensure the requested quantity aligns with manufacturer minimum order requirements. Confirm RoHS compliance status through the latest datasheet revision. Check for any regional distribution restrictions or lifecycle notices prior to finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel analog switch is required within the HC logic family. Verify that the supply voltage range of 2V to 6V matches the system design. Ensure the SOIC-16 package fits the PCB layout constraints. Compare propagation delay and on-resistance parameters against other available multiplexer options if signal integrity is critical.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part is part of the HD74HC series, which represents Renesas's implementation of standard 74HC logic functions. It serves as a direct replacement for generic 74HC4051 devices from other manufacturers. The FP designation typically indicates a plastic package, while K often refers to the specific reel packaging format used for surface mount assembly.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible substitutes include the 74HC4051D from Toshiba and MM74HC4051MX from onsemi. Verify electrical characteristics such as on-resistance and propagation delay to ensure compatibility with existing circuit designs before swapping components.
