MAX4561EUT

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4561EUT+T is a single-pole/double-throw (SPDT) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +1.8V to +12V supply and features ±15kV ESD protection on NO/NC terminals. Key electrical parameters include an on-resistance of 70Ω at +5V and 120Ω at +3V, with a maximum match between channels of 2Ω. Turn-on time is typically 90ns and turn-off time is 40ns at +5V. The device offers low off-leakage current of 0.5nA at +25°C and supports rail-to-rail signal handling. It is housed in a 6-pin SOT23 package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Provides robust ±15kV electrostatic discharge protection on normally open and normally closed inputs without latchup or damage.
• Ensures high signal integrity through guaranteed on-resistance matching of 2Ω maximum and flatness of 4Ω maximum over the signal range.
• Supports break-before-make switching action to prevent signal overlap during transitions.
• Compatible with TTL and CMOS logic levels when powered by a single +5V supply.

Analog Switches, Multiplexers, Demultiplexers Applications

• High-ESD environments requiring durable signal routing
• Battery-powered systems due to low-voltage operation
• Audio and video signal routing applications
• Low-voltage data-acquisition systems
• Sample-and-hold circuits

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix '+T' indicates tape and reel packaging when sourcing this component. Confirm that the 'E' suffix corresponds to the -40°C to +85°C operating temperature range required for your specific application environment. Ensure compatibility with the 6-pin SOT23 footprint during procurement planning.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4561EUT+T for designs requiring SPDT configuration with high ESD tolerance. Compare its 70Ω on-resistance against other switches if lower insertion loss is critical. Consider the 90ns turn-on time for timing-sensitive digital control interfaces. Verify that the single-supply voltage range meets the system's power constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4561/MAX4568/MAX4569 family of low-voltage, ESD-protected analog switches. While the MAX4568 and MAX4569 variants offer SPST configurations in 5-pin packages, the MAX4561 specifically provides SPDT functionality in a 6-pin SOT23 package. All members share similar electrical characteristics and pinout compatibility within their respective categories.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet notes that the MAX4561 is pin-compatible with the MAX4544. Designers should verify that the MAX4544 meets all specific electrical requirements before substitution. No other direct substitutes are explicitly listed in the provided documentation.
