MAX4581ESE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4581ESE+T is a low-voltage CMOS analog multiplexer featuring eight channels in a 16-pin Narrow SO package. It operates on single supplies from +2V to +12V or dual supplies of ±2V to ±6V. Key electrical parameters include an on-resistance of 80Ω (±5V) or 150Ω (+5V), off-leakage current of 1nA at +25°C, and total harmonic distortion below 0.02%. The device supports TTL/CMOS logic thresholds and offers high off-isolation exceeding -74dB.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range of -40°C to +85°C. Confirm the '+T' designation corresponds to tape-and-reel packaging. Ensure the narrow SO package type matches the required footprint. Cross-reference the lead-free/RoHS compliance status indicated by the '+' symbol. Validate that the ordering code aligns with the manufacturer's current documentation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel multiplexing function is required within a compact surface-mount package. Consider the MAX4581 series for applications needing rail-to-rail analog signal support. Evaluate the on-resistance specifications against the load requirements. Verify that the operating voltage range fits the system's power architecture. Check if the automotive-qualified variants are necessary for harsh environments.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4581/MAX4582/MAX4583 family of low-voltage CMOS analog switches. The MAX4581 specifically provides an 8-channel multiplexer configuration. It is pin-compatible with industry-standard 74HC4051 devices but offers superior electrical performance. The family includes variations for different channel counts and switch types.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4581CSE+ serves as a commercial grade alternative with a 0°C to +70°C range. The MAX4581EEE+ offers the same electrical specs in a QSOP package. Direct substitutes must match the 8-channel multiplexer topology and 16-pin narrow SO footprint.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4581 handle overvoltage conditions?

Internal reverse ESD-protection diodes connect each analog-signal pin to VCC and VEE. If a signal exceeds these rails, the diodes conduct, potentially causing leakage current.

What is the logic input threshold compatibility?

Digital inputs have 0.8V to 2.4V logic thresholds, ensuring compatibility with TTL and CMOS logic when using single +5V or dual ±5V supplies.

Can the MAX4581 operate with asymmetrical supplies?

Yes, the VCC and VEE supplies need not be symmetrical, provided their sum does not exceed the absolute maximum rating of +13V.
