MAX4854HETE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4854HETE is a quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features over-rail signal handling capabilities, allowing operation with signals exceeding the supply rails. The device operates on a single 2.7V to 36V supply or dual ±1.35V to ±18V supplies. Key electrical parameters include an on-resistance of 7Ω maximum, an on-resistance matching of 0.1Ω, and a channel-to-channel isolation of 70dB at 1MHz. It supports a continuous current of 100mA per channel and 200mA total, with a breakdown voltage of ±36V.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Quad SPST configuration providing four independent switching channels in a compact package
• Over-rail signal handling capability enabling control of signals outside the power supply range
• Low on-resistance of 7Ω ensures minimal signal attenuation across the switch path
• High channel-to-channel isolation reduces crosstalk between adjacent switching paths

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in test and measurement equipment requiring high-voltage signal handling
• Multiplexing applications in industrial data acquisition systems
• Audio signal switching where low distortion and high isolation are required
• Programmable gain amplifier input selection circuits

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix HETE corresponds to the TQFN-EP-16 package and industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation. Ensure ordering codes match the exact pinout and thermal pad requirements for PCB layout compatibility.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when multiple independent switches are needed within a single integrated circuit footprint. The over-rail feature makes it suitable for applications where signal levels may exceed the logic supply voltage. Compare on-resistance stability and leakage current specifications against alternative quad SPST switches if precise linearity is critical for the application.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4854 belongs to Maxim's family of high-voltage analog switches designed for robust signal processing. Unlike standard CMOS switches, this series accommodates over-rail conditions without damage. It serves as a building block for complex switching matrices and multiplexer designs in environments demanding high voltage tolerance and reliable signal integrity.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4854HLETE is a verified equivalent offering identical functionality with leaded termination options. Cross-reference with MAX4851 for similar quad SPST performance. Verify pin compatibility before substituting with other quad SPST devices from different manufacturers.
