Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the complete part number including the suffix '-E3' to confirm RoHS compliance status. Ensure the ordering suffix matches the required tape and reel packaging format for automated assembly processes. Cross-reference the manufacturer's latest documentation to validate any revisions to the pinout or electrical specifications before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single-pole double-throw (SPDT) topology is required for analog signal routing. The narrow SOIC package is appropriate for applications demanding high board space efficiency. Verify that the maximum supply voltage and on-resistance limits align with the specific circuit requirements and operating temperature conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the DG417 series of monolithic CMOS analog switches. It shares the same physical package and general performance characteristics as the DG417 and DG418 models, differing primarily in its internal SPDT configuration compared to the SPST configurations of the other variants in the family.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the guaranteed switching characteristic for the DG419?

The DG419 guarantees break-before-make switching action, which prevents the simultaneous connection of both common terminals during state transitions.

How does the DG419 handle signals exceeding the supply rails?

Signals on the source or drain pins exceeding the positive or negative supply levels are clamped by internal diodes, requiring the forward diode current to be limited to the maximum ratings.

Is the DG419 susceptible to latch-up?

No, an epitaxial layer is included in the construction to prevent latch-up under normal operating conditions.
