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 four switches with two normally open and two normally closed configurations. The device operates from a single +2V to +12V supply. Key electrical parameters include a maximum on-resistance of 100Ω at +5V and 46Ω at +12V, with channel matching guaranteed to 4Ω max and flatness to 18Ω max. Off-leakage current is limited to 1nA at +25°C and 2nA at +85°C. The package is a 14-pin Narrow SOIC, and the operating temperature range is -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Rail-to-rail signal handling capability across the full supply voltage range.
• TTL/CMOS logic compatibility ensuring reliable interface with standard digital control signals.
• High off-isolation and low charge injection for accurate signal routing.
• Robust ESD protection rated at 2kV per Method 3015.7.

Analog Switches, Multiplexers, Demultiplexers Applications

• 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 'ESD' corresponds to the 14-pin Narrow SOIC package and the -40°C to +85°C industrial temperature grade. Confirm RoHS compliance status as indicated by the '+' designation in the ordering information. Ensure the source documentation matches the manufacturer's official datasheet for the MAX4610/MAX4611/MAX4612 family to validate pinout and electrical specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a mixed NO/NC SPST configuration is required within a single package. The MAX4612 differs from the MAX4610 (all NO) and MAX4611 (all NC). Consider the 100Ω on-resistance limit at +5V operation. Verify that the narrow SOIC footprint fits the PCB layout constraints compared to TSSOP or DIP alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4612ESD belongs to the MAX4610/MAX4611/MAX4612 family of low-voltage CMOS analog switches. These devices are pin-compatible with industry-standard parts like the 74HC4066 but offer optimized performance for single-supply operation. The family provides flexibility through different switch configurations (NO, NC, or mixed) while maintaining consistent electrical characteristics and packaging options.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include MAX4610ESD (four NO switches) and MAX4611ESD (four NC switches), provided the specific NO/NC mix of the MAX4612 is not critical. Other packages such as TSSOP (MAX4612EUD+) or PDIP (MAX4612EPD+) offer the same electrical functionality with different mechanical footprints.
