MAX4612ESD+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4612ESD+ is a low-voltage, quad, single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features two normally open and two normally closed switches within a 14-pin Narrow SO package. The device operates from a single +2V to +12V supply with a maximum on-resistance of 100Ω at +5V and 46Ω at +12V. On-resistance is matched between channels to 4Ω max and flat over the signal range to 18Ω max. Off-leakage current is limited to 1nA at +25°C and 2nA at +85°C. The component supports rail-to-rail signal handling, offers 2kV ESD protection, and functions within an operating temperature range of -40°C to +85°C.

• Low-voltage data-acquisition systems
• Sample-and-hold circuits
• Communication circuits

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'ESD+' corresponds to the 14-pin Narrow SO package and the -40°C to +85°C industrial temperature grade. Confirm that the lead-free/RoHS-compliant designation matches project requirements. Ensure the component source is authorized to guarantee authenticity and traceability for this specific part number.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4612ESD+ when a mixed configuration of two normally open and two normally closed SPST switches is required in a narrow surface-mount footprint. This part is suitable for designs needing TTL/CMOS logic compatibility and operation from a single low-voltage supply ranging from +2V to +12V.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4612ESD+ belongs to the MAX4610/MAX4611/MAX4612 family of low-voltage CMOS analog switches. While pin-compatible with industry-standard devices like the 74HC4066, it offers optimized performance for single-supply operation. The 'E' suffix indicates the extended temperature range, and 'SD' specifies the 14-pin Narrow SOIC package type.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4610ESD+ and MAX4611ESD+ are pin-compatible alternatives within the same family. Verify if the specific NO/NC channel configuration of the MAX4612 is strictly necessary or if all-open or all-closed variants suffice.
