Procurement Notes
Verify the specific suffix 'QTR' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the operating temperature range meets the environmental specifications of the target application. Ensure compatibility with the control logic voltage levels used in the design.
Selection Notes
Select this component when a dual-channel SPDT switching solution is required with low power consumption. Consider the package size constraints and the need for high isolation in signal integrity critical designs. Evaluate the supply voltage requirements against the available system rails to ensure proper operation within the specified limits.
Part Context
This part belongs to the family of analog switches from STMicroelectronics, designed for general-purpose signal switching. It serves as a compact alternative to mechanical relays in space-constrained designs. The QFN package facilitates surface mount technology integration into modern electronic assemblies.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the source material. Verify pin-to-pin compatibility and electrical parameter equivalence before considering alternative components from other manufacturers.
