MAX4514EUK+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4514EUK+T is a single-pole/single-throw (SPST) CMOS analog switch housed in an SOT-23-5 package. It operates on a single supply voltage ranging from +2V to +12V and features very low on-resistance, guaranteed at 20Ω with a +5V supply and 10Ω with a +12V supply. The device handles rail-to-rail analog signals and offers fast switching speeds with a maximum turn-on time of 150ns and turn-off time of 100ns. It maintains low off-leakage currents of 1nA at +25°C and includes break-before-make operation for signal integrity.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Single-supply operation compatible with +2V to +12V power rails
• Low on-resistance ensuring minimal signal attenuation
• Break-before-make switching action prevents signal shorting
• TTL/CMOS logic compatibility for direct digital control

Analog Switches, Multiplexers, Demultiplexers Applications

• Battery-operated equipment

• Low-voltage data-acquisition systems
• PCMCIA cards
• Cellular phones and modems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +85°C). Confirm the '+T' designation corresponds to tape-and-reel packaging. Ensure the component matches the SOT-23-5 footprint requirements for your PCB layout. Cross-reference the manufacturer's latest datasheet for any updates to absolute maximum ratings or pin configurations before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally open SPST switch is required for low-voltage applications. The E-grade variant is necessary if the operating environment exceeds standard commercial temperatures. Consider the 20Ω on-resistance limit for signal loss calculations. Verify that the input logic levels align with the system's digital supply voltage to ensure proper switching thresholds.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4514/MAX4515 family of low-voltage analog switches. The MAX4514 variant is specifically designed as a normally open switch, whereas the MAX4515 is normally closed. Both share identical electrical characteristics and pinouts, differing only in their default state. The E-series designation extends the operational temperature range compared to the C-series parts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the MAX4515EUK+T for normally closed functionality. For dual-supply applications, consider the MAX4516 or MAX4517 series. Verify that any substitute maintains the same SOT-23-5 package and meets the required on-resistance and leakage current specifications.
