74LVC2G66DC-Q100H

Analog Switches, Multiplexers, Demultiplexers Overview

The Nexperia 74LVC2G66DC-Q100H is an automotive-qualified dual single pole, single throw (SPST) analog switch housed in a VSSOP8 package. It operates on a supply voltage range of 1.65 V to 5.5 V with inputs tolerant up to 5.5 V. The device features Schmitt-trigger action for slow input transitions and provides a typical ON resistance of 6.5 Ω at 3.3 V. Key dynamic characteristics include a maximum propagation delay of 1.0 ns at 5.5 V and enable/disable times up to 6.5 ns. It supports a switch current capability of 32 mA and meets AEC-Q100 Grade 1 standards for operation between -40 °C and +125 °C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Overvoltage tolerant inputs allowing interface with 5 V logic
• Schmitt-trigger inputs ensure tolerance for slower rise and fall times
• Low power consumption with CMOS technology

Analog Switches, Multiplexers, Demultiplexers Applications

• Mixed 3.3 V and 5 V signal translation environments
• Automotive electronic systems requiring qualified components
• Portable applications utilizing low-power active high enable inputs

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'H' against the manufacturer's official documentation to confirm if it denotes a specific tape and reel configuration or environmental compliance variant distinct from the standard DC part number. Ensure the ordering code matches the required VSSOP8 package type SOT765-1 for correct physical integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual SPST bilateral switch is required for automotive-grade designs. It is suitable for applications needing overvoltage tolerant inputs and Schmitt-trigger action to handle slow signal edges. Verify that the 32 mA switch current capability and the specific ON resistance values at your operating voltage meet the circuit requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the 74LVC2G66-Q100 family of bilateral switches manufactured by Nexperia. It shares functional similarities with other LVC series switches but is specifically qualified for automotive use under AEC-Q100 Grade 1. The DC suffix indicates the VSSOP8 plastic very thin shrink small outline package variant.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The 74LVC2G66DP-Q100H serves as a pin-compatible alternative using the TSSOP8 package. For non-automotive applications, the standard 74LVC2G66 may be considered if AEC-Q100 qualification is not required.
