MAX4560CEE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4560CEE+ is a low-voltage CMOS analog switch configured as three single-pole/double-throw (SPDT) switches in a 16-pin QSOP package. It operates from dual supplies of ±2V to ±6V or a single +2V to +12V supply. The device features ±15kV ESD protection on signal pins, TTL/CMOS-compatible logic inputs, and handles Rail-to-Rail analog signals. Key electrical parameters include a maximum on-resistance of 220Ω at +5V single supply, 1nA off-leakage current at +25°C, and a typical channel-to-channel on-resistance match of 2Ω.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrated ±15kV electrostatic discharge protection on all analog signal pins using on-chip bidirectional SCRs.
• TTL and CMOS logic compatibility with defined input thresholds for reliable interfacing across various supply voltages.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CEE+' corresponds to the commercial temperature range and RoHS-compliant QSOP packaging. Confirm that the ordering code matches the exact pinout and functional requirements for triple SPDT switching. Ensure the design accounts for the specified absolute maximum ratings to prevent latchup during ESD events.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when triple independent SPDT switching is required in a compact surface-mount format. Consider the on-resistance flatness and leakage specifications relative to the intended signal amplitude and frequency. Verify that the system's digital logic levels align with the device's input thresholds at the chosen supply voltage.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4558/MAX4559/MAX4560 family of low-voltage CMOS analog multiplexers and switches. While the MAX4558 offers an 8-to-1 configuration and the MAX4559 provides dual 4-to-1 multiplexing, the MAX4560 specifically delivers three independent SPDT switches. All members share similar ESD protection and low-power characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements within the same family include MAX4558 and MAX4559 variants, though their internal switching configurations differ significantly. Industrial grade equivalents with extended temperature ranges are available as MAX4560EEE+.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the ESD protection mechanism function?

The device uses on-chip bidirectional silicon-controlled rectifiers (SCRs) between the protected signal pins and ground. These SCRs remain off during normal operation but turn on rapidly during an ESD strike to bypass surge current safely to ground.

What is the logic threshold behavior at higher supply voltages?

At +5V, the inputs are TTL/CMOS compatible. As VCC rises to +12V, the logic high threshold increases slightly to approximately 3.1V, which remains compatible with standard CMOS outputs despite exceeding the minimum TTL high-level guarantee.

Why must connected sources be current-limited?

Once an SCR latches due to an ESD event, it requires the current through it to fall below a holding current (typically 70mA to 110mA depending on polarity and temperature) to turn off. Sources must be limited to half these values to ensure the SCR resets after an event.
