HCF4053BEY

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.

Feature Summary

• Integrates three independent double-throw analog switches sharing common control lines
• Provides bidirectional signal path capability for both analog and digital signals
• Features extremely low quiescent power consumption independent of logic states
• Includes an active-high inhibit function that turns off all channels simultaneously

Applications

• Signal routing in data acquisition systems
• Audio channel switching and mixing circuits
• Multiplexing multiple sensor inputs to a single ADC
• Test and measurement equipment signal selection

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.

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.

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.

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.
