Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix designation to confirm tape-and-reel packaging versus tube options. Confirm RoHS compliance status as legacy variants may differ. Check current availability as this component may be subject to limited stock or end-of-life restrictions depending on the manufacturing batch date code.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single-channel analog switch with low on-resistance is required. Ensure the application voltage does not exceed the 30V single-supply limit. Consider the 8-uMAX package size for space-constrained designs. Verify logic compatibility if interfacing with lower voltage microcontrollers.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG418 series of improved SPST/SPDT analog switches from Maxim Integrated. It serves as a replacement for older discrete switching solutions in compact PCB layouts. The uMAX package offers a small footprint suitable for surface-mount assembly processes in modern electronic devices.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the DG418CY+ and DG418DJ variants, which offer identical electrical specifications but utilize different package formats such as SOIC-8 or PDIP-8. Ensure pinout compatibility before swapping between package types.
