MAX4854HETE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4854HETE+T is a quad single-pole/single-throw (SPST) analog switch from the MAX4854H series, manufactured by Analog Devices Inc. It operates on a single +2V to +5.5V supply and features four low on-resistance switches with an on-resistance of 7 Ω typical at +25°C. The device includes overvoltage protection that forces the switch into a high-impedance state when input signals exceed the supply rail. It offers a -3dB bandwidth of 150 MHz, 27.5 pF on-capacitance, and a maximum turn-on time of 100 ns. The component is housed in a 16-pin thin QFN package (3mm x 3mm) and supports an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'ETE' corresponds to the TQFN-EP package and reel tape packaging format as listed in the ordering information. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring bidirectional switching with guaranteed skew less than 1ns. Ensure power-supply sequencing applies VCC before analog signals to prevent damage. Verify that the 7Ω on-resistance meets the impedance requirements of the target application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4854H/MAX4854HL family of quad SPST analog switches. The 'H' variant indicates Normally Open (NO) terminals, while the 'L' variant indicates Normally Closed (NC) terminals. Both variants share identical electrical characteristics and package dimensions.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4854H handle signals exceeding the supply voltage?

When the input signal exceeds the supply rail (VCC), the switches enter a high-impedance state, preventing the signal from feeding through to the output.

What is the logic voltage compatibility for the control inputs?

The digital control inputs (IN_) accept up to +5.5V even if the supply voltage is lower, such as +3.3V or +2V, allowing for mixing of logic levels within the system.

Is the MAX4854H suitable for differential signal switching?

Yes, it is designed to switch D+ and D- USB signals with a guaranteed skew of less than 1ns, making it suitable for differential data lines.
