Overview
The SN74LVC1G66DCKRG4 is a single-channel SPST analog switch manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.65 V to 5.5 V. The device features a maximum on-resistance of 10 Ohms and supports a DC switch current of 100 mA. Electrical performance includes a maximum propagation delay of 4.2 ns and an off-time of 5 ns. Quiescent current is limited to 100 nA maximum. It functions within an operating temperature range of -40°C to +85°C and is housed in a SC70-5 surface-mount package.
Feature Summary
- Provides low on-resistance for efficient signal transmission across the operating voltage range.
- Supports high DC switch current capability suitable for driving various loads.
- Features low quiescent current consumption to minimize power usage during operation.
Applications
- Battery-powered systems requiring low power consumption
- Portable equipment utilizing single-supply operation
- Consumer electronics involving signal routing
Procurement Notes
Verify component authenticity through authorized channels, as the SN74LVC1G66DCKRG4 is designated as obsolete with end-of-life status. Confirm that the specific SC70-5 package variant matches design requirements before integration. Review official documentation for any physical or electrical specification changes associated with the obsolescence notice to ensure continued compliance with system specifications.
Selection Notes
Select this component when a single bilateral analog switch is required within the LVC logic family. Ensure the application voltage stays between 1.65 V and 5.5 V. Verify that the SC70-5 footprint fits the PCB layout constraints. Consider the 10 Ohm on-resistance and 100 mA current limit against load requirements. Check if the -40°C to +85°C industrial temperature range meets environmental needs.
Part Context
This part belongs to the SN74LVC1G66 series of single-pole single-throw (SPST) analog switches. It shares core electrical characteristics with other variants like the SN74LVC1G66DBVTG4 and SN74LVC1G66DRYR, differing primarily in packaging. The DCKR suffix indicates the SC70-5 package type used for space-constrained surface-mount designs.
Replacement Considerations
The SN74LVC1G66DBVTG4 offers identical electrical performance in an SOT-23-5 package. The SN74LVC1G66DRYR provides the same functionality in a SON-6 package. These parts serve as direct functional substitutes with pin-compatible or adaptable footprints depending on board layout adjustments.
