MAX4618EUE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4618EUE+ is a high-speed, low-voltage CMOS analog multiplexer IC configured as two independent 4:1 channels. It operates on a single +2V to +5.5V supply and supports rail-to-rail analog signal handling. The device features fast switching times with a maximum turn-on time of 20ns and turn-off time of 15ns at +3V. On-resistance is guaranteed at 20Ω max (+3V) or 10Ω max (+5V), with channel matching within 1Ω. Off-leakage current is limited to 1nA at +25°C. Digital inputs are TTL/CMOS compatible, and the component is housed in a 16-pin TSSOP package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Pin-compatible with industry-standard 74HC4051/74HC4052/74HC4053 and MAX4581/MAX4582/MAX4583 for direct replacement in existing designs.
• Provides low crosstalk below -96dB and high off-isolation below -93dB for clean signal routing.
• Ensures low distortion performance with total harmonic distortion less than 0.017% under specified load conditions.

Analog Switches, Multiplexers, Demultiplexers Applications

• Battery-operated equipment requiring low power consumption
• Audio and video signal routing systems
• Low-voltage data-acquisition systems
• Communications circuits

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the specific part number suffix matches the required temperature range and packaging format. The 'E' suffix indicates an industrial temperature range of -40°C to +85°C, while 'C' denotes commercial range. Ensure the '+T' suffix is present if tape-and-reel packaging is required rather than tube packaging. Confirm RoHS compliance status based on the '+' designation in the ordering information.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual 4:1 multiplexing functionality is needed within a single package. Consider the MAX4617 if eight channels are required, or the MAX4619 for SPDT switch applications. Evaluate the on-resistance requirements against the available supply voltage, as resistance increases significantly at lower voltages like +2.5V. Ensure the logic thresholds align with the system's digital control levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4617/MAX4618/MAX4619 family of high-speed, low-voltage CMOS analog switches manufactured by Analog Devices (Maxim Integrated). The family shares identical pinouts and logic diagrams but differs in internal configuration. The MAX4618 specifically provides two separate 4-channel multiplexers, offering flexibility for differential signal paths or dual independent signal sources compared to the single 8-channel MAX4617.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the MAX4617 and MAX4619 from the same series, provided the channel count meets design needs. Industry-standard 74HC4051, 74HC4052, and 74HC4053 devices are also pin-compatible, though electrical specifications such as on-resistance and leakage may differ. Verify that any substitute maintains the required single-supply operation range and logic compatibility.
