DG419DY selection and design context
DG419DY is cataloged as a Analog Switch in the DG419 family. Its recorded function is precision SPDT CMOS analog switch supporting bipolar analog signals. Selection should be based on the complete electrical limits, package drawing and ordering suffix rather than the abbreviated family code.
- Configuration: Single SPDT analog switch. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- Analog Signal Range: ±15 V. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- On Resistance: 20 Ω. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- Turn-On Time: 100 ns typical. Confirm the value and its datasheet test conditions for the exact ordering suffix.
Application and qualification considerations
When evaluating this component, confirm the ratings that control system compatibility, including supply conditions, interface or signal limits, timing, thermal behavior and package constraints. For a new design, review power-up behavior, interface timing, absolute maximum ratings, thermal limits and any external-component requirements in the latest manufacturer documentation. Existing-board replacement work should additionally confirm pinout, footprint, firmware assumptions and qualification grade.
Procurement checks for DG419DY
