HCF4097M013TR

Analog Switches, Multiplexers, Demultiplexers Overview

The HCF4097M013TR is a dual 8-to-1 multiplexer/demultiplexer manufactured by STMicroelectronics. It integrates two independent 8:1 MUX/DEMUX circuits within a single 24-SOIC package. The device operates on a single power supply ranging from 3V to 20V. Key electrical specifications include a maximum on-resistance of 240 ohms and a channel-to-channel matching of 5 ohms. Leakage current is limited to 100µA, with channel capacitance values of 0.2pF and 5pF. Crosstalk is specified at -40dB @ 1MHz. The component supports an operating temperature range of -55°C to 125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

This specific part number is officially obsolete and no longer manufactured by STMicroelectronics. Verification of availability should focus on secondary market distributors or surplus stock holders rather than direct manufacturer channels. Designers must confirm the authenticity of existing inventory through authorized supply chain partners to avoid counterfeit components. Lifecycle status requires immediate attention for long-term production planning.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Engineers selecting this component should verify compatibility with the 24-SOIC footprint and ensure the 240-ohm on-resistance meets system requirements. Since the part is discontinued, alternative sources must be evaluated for quality assurance. Consider the operating temperature range of -55°C to 125°C against environmental conditions. Electrical parameters such as crosstalk and leakage should be compared against current design constraints before finalizing procurement strategies.

Analog Switches, Multiplexers, Demultiplexers Part Context

The HCF4097 series belongs to STMicroelectronics' high-voltage CMOS logic family. This specific variant includes the 'M013' suffix indicating tape-and-reel packaging for surface-mount technology. It is part of the broader HCF4097B product line, which shares similar functional characteristics but may differ in packaging or minor electrical tolerances. The component serves as a solid-state switch solution for analog and digital signals.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The CD4097BM from Texas Instruments is documented as a similar replacement option. Engineers should verify pinout compatibility and electrical parameter alignment between the original STMicroelectronics part and the Texas Instruments substitute before implementation.
