MAX4612EUD+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4612EUD+ is a low-voltage, quad, single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices/Maxim Integrated. It operates from a single +2V to +12V supply and features two normally open (NO) and two normally closed (NC) switches. The device offers a maximum on-resistance of 100Ω at +5V and 46Ω at +12V, with guaranteed channel matching of 4Ω max and flatness of 18Ω max over the signal range. Off-leakage current is limited to 2nA at +85°C. It provides 2kV ESD protection per Method 3015.7 and ensures TTL/CMOS logic compatibility at +5V. The component is housed in a 14-pin TSSOP package and supports an operating temperature range of -40°C to +85°C.

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

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EUD+' corresponds to the -40°C to +85°C automotive-grade temperature range and the 14-pin TSSOP surface-mount package configuration. Confirm RoHS compliance status as indicated by the '+' designation in official ordering information. Ensure the source documentation explicitly lists this part number variant to avoid confusion with non-automotive or different package options within the MAX4612 family.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4612EUD+ when a mixed configuration of two normally open and two normally closed SPST switches is required. This part is suitable for applications needing rail-to-rail signal swing and low leakage currents under varying temperatures. Consider the 100Ω on-resistance limit at +5V operation when designing for higher impedance signal paths. Verify that the single-supply voltage range of +2V to +12V aligns with the system power architecture.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4612EUD+ belongs to the MAX4610/MAX4611/MAX4612 family of low-voltage CMOS analog switches. While the MAX4610 provides four normally open switches and the MAX4611 provides four normally closed switches, the MAX4612 combines both types. All variants share identical pinouts and electrical characteristics regarding resistance and leakage, differing only in the internal switch state configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4610 and MAX4611 are pin-compatible alternatives within the same family but offer different switch configurations (all NO or all NC). Industry-standard 74HC4066 devices are also pin-compatible but may differ in on-resistance and voltage specifications. Verify functional requirements before substituting.
