HCF4053BEY

Analog Switches, Multiplexers, Demultiplexers Overview

The HCF4053BEY is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology, functioning as a triple 2-channel analog multiplexer/demultiplexer. It integrates three independent SPDT switches controlled by common digital inputs A, B, and C, along with an inhibit input. The device operates within a supply voltage range of 3V to 20V for single supply or ±1.5V to ±10V for dual supply configurations. Key electrical parameters include a typical ON resistance of 70 Ω at VDD-VSS=10V and a maximum OFF leakage current of 1 nA at VDD-VSS=18V. It supports bidirectional signal transmission with low quiescent power dissipation.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'BEY' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets required radiation hardness or temperature grade if used in harsh environments, as standard commercial grades differ from hermetic variants like M54HC4053. Cross-reference ordering codes with authorized distributors to avoid counterfeit parts.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a compact solution for three independent 2-to-1 analog switches is required. Compare ON resistance and leakage current specifications against application signal integrity requirements. Consider the PDIP-16 or SO-16 package availability based on PCB layout constraints. Verify that the control logic voltage levels are compatible with the chosen supply voltage range.

Analog Switches, Multiplexers, Demultiplexers Part Context

The HCF4053 belongs to the HC/HCT CMOS logic family, designed for general-purpose analog switching applications. It serves as a functional equivalent to other industry-standard triple 2-channel multiplexers. The BEY suffix typically denotes a specific packaging configuration, such as tube or reel, provided by STMicroelectronics for volume manufacturing.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible substitutes include the CD4053B and HEF4053B. Verify that alternative manufacturers maintain identical ON resistance and leakage current characteristics. Ensure control logic compatibility between HC and HCT series if TTL-level inputs are utilized.
