MAX4612CSD+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4612CSD+T is a quad, low-voltage, 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 an on-resistance of 100Ω max at +5V and 46Ω max at +12V, with channel matching of 4Ω max and flatness of 18Ω max. Off-leakage current is 30nA max at +25°C and 2µA max at +125°C. Switching times are 65ns max for turn-on and 28ns max for turn-off at +5V. The package is a 14-pin Narrow SOIC.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm the specific suffix matches the required temperature range and packaging format. Ensure compliance with RoHS standards as indicated by the plus sign in the part number. Cross-reference the datasheet revision to confirm pinout and electrical characteristics align with design requirements before integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a mix of normally open and normally closed analog switching is required within a single package. Consider the on-resistance variation with supply voltage; higher voltages reduce resistance. Evaluate the leakage current specifications against the application's sensitivity requirements, particularly at elevated temperatures. Ensure the logic input thresholds match the driving circuit's output levels for proper switching operation.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4610/MAX4611/MAX4612 family of low-voltage SPST CMOS analog switches. While the MAX4610 offers four normally open switches and the MAX4611 provides four normally closed switches, the MAX4612 combines two of each type. All variants share similar electrical characteristics and pinouts, facilitating flexible design options for mixed signal paths.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Pin-compatible alternatives include the MAX4610 and MAX4611 if the specific NO/NC configuration can be adapted. The industry-standard 74HC4066 is also pin-compatible but may differ in electrical performance specifications such as on-resistance and leakage current. Verify functional equivalence before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4610, MAX4611, and MAX4612?

The MAX4610 contains four normally open (NO) switches. The MAX4611 contains four normally closed (NC) switches. The MAX4612 contains two normally open and two normally closed switches.

Can the MAX4612 operate with dual supplies?

The datasheet specifies operation from a single +2V to +12V supply. While rail-to-rail handling is supported, the documentation emphasizes single-supply operation.

How does the on-resistance vary with supply voltage?

On-resistance decreases as supply voltage increases. At +5V, it is 100Ω max, while at +12V, it drops to 46Ω max.
