MAX4066ACSD

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4066ACSD is a quad, single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from +2.0V to +16V and is fully specified at 3V, 5V, and 12V. The device features an on-resistance of 45Ω maximum at 12V and 170Ω maximum at 3V, with channel-to-channel matching of 2Ω maximum at 12V for the 'A' variant. It offers low off-leakage current of 100pA at +25°C, power consumption of 0.5µW, and wide bandwidth exceeding 100MHz. The component is housed in a 14-pin Narrow SO package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix ACSD confirms the commercial temperature grade (0°C to +70°C) and the narrow small-outline package format. Confirm that the 'A' designation indicates the tighter channel matching specifications compared to the standard MAX4066. Ensure the source document explicitly lists this part number as available or discontinued status before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4066ACSD when pin compatibility with 74HC4066 is required alongside superior performance metrics. Choose this component over the standard MAX4066 if tighter channel-to-channel matching (2Ω vs 4Ω) and lower leakage currents are necessary for precision applications. Consider the 14-pin narrow SO package constraints for PCB layout requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4066/MAX4066A family of low-cost, low-voltage analog switches. The 'A' suffix denotes improved leakage and matching characteristics compared to the base model. The 'C' indicates the commercial temperature range, while 'SD' specifies the 14-pin narrow SOIC package type within the broader product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet notes pin compatibility with the 74HC4066. However, verify electrical parameter differences such as on-resistance and leakage currents before substitution. No other specific substitute part numbers are confirmed in the provided documentation.
