MAX4582CUE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4582CUE+ is a low-voltage CMOS analog multiplexer IC configured as two independent 4-channel multiplexers. It operates with dual supplies of ±2V to ±6V or a single supply of +2V to +12V. The device features rail-to-rail analog signal handling, an off-leakage current of 1nA at +25°C, and TTL/CMOS logic compatibility. Electrical specifications include a maximum on-resistance of 80Ω with ±5V supplies, a channel-to-channel on-resistance match of 1Ω, and a typical crosstalk of -96dB at 1MHz. It is housed in a 16-pin TSSOP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C) rather than extended automotive grades. Confirm the 'UE+' designation corresponds to the 16-TSSOP lead-free package. Cross-reference the manufacturer's official ordering guide for any recent pinout or electrical specification updates before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 4-channel multiplexer configuration is required within a single package. Ensure the application voltage falls within the +2V to +12V single-supply or ±2V to ±6V dual-supply limits. Verify that the 80Ω on-resistance meets the system's signal integrity requirements and that the 16-TSSOP footprint aligns with the PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4581/MAX4582/MAX4583 family of low-voltage CMOS analog switches. While the MAX4581 provides an 8-channel multiplexer and the MAX4583 offers three SPDT switches, the MAX4582 specifically integrates two 4-channel multiplexers. All variants share identical pinouts and logic diagrams for interchangeability.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Pin-compatible alternatives include the industry-standard 74HC4052 and the Maxim MAX4052. These devices function identically regarding logic diagrams but may differ electrically in parameters such as on-resistance and leakage current. Verify electrical specifications against the original design requirements before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the logic input threshold voltage for the MAX4582CUE+?

The device has logic thresholds ranging from 0.8V to 2.4V, ensuring compatibility with TTL and CMOS logic levels when using a single +5V or dual ±5V supply.

How does the MAX4582 handle overvoltage conditions?

Internal reverse ESD-protection diodes connect each analog-signal pin to both VCC and VEE. If an analog signal exceeds these supply rails, the diodes conduct to clamp the voltage.

Is the MAX4582 suitable for high-frequency applications?

In 50Ω systems, the signal response remains reasonably flat up to 50MHz. However, off-isolation degrades at higher frequencies due to capacitive coupling effects.
