MAX4612CSD

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4612CSD+ is a quad, low-voltage, 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 maximum on-resistance of 100Ω at +5V and 46Ω at +12V. On-resistance is matched between channels to 4Ω max and flat to 4Ω max over the signal range. Off-leakage current is limited to 1nA at +25°C and 2nA at +85°C. Turn-on time is 65ns max and turn-off time is 28ns max at +5V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix CSD+ corresponds to the 14-pin Narrow SO package and commercial temperature range (+0°C to +70°C). Confirm RoHS compliance status as indicated by the plus sign in the part number. Ensure the component source provides valid traceability documentation for the Analog Devices/Maxim Integrated manufacturer identification.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a mixed configuration of normally open and normally closed analog switches is required in a compact surface-mount package. The narrow SO footprint suits space-constrained designs. Verify that the single-supply voltage range meets the system requirements and that the on-resistance specifications align with the application's signal integrity needs.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4610/MAX4611/MAX4612 family of low-voltage CMOS analog switches. The MAX4612 variant specifically combines two NO and two NC switches, distinguishing it from the all-NO MAX4610 and all-NC MAX4611. All variants share identical pinouts and electrical characteristics, facilitating design flexibility within the same package constraints.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4612CSD+ is pin-compatible with the industry-standard 74HC4066 and the MAX4066. Designers may consider these alternatives if specific MAXIM Integrated sourcing is unavailable, provided the electrical parameters meet the original design requirements.
