Diode Arrays Procurement Notes

Verify obsolescence status before design finalization, as the component is marked as discontinued. Confirm that the 14-DIP through-hole package remains compatible with existing PCB footprints. Ensure that the 75V standoff voltage aligns with the target circuit's operating parameters. Check for available legacy stock from authorized distributors if immediate replacement is required.

Diode Arrays Selection Notes

Select this component when eight-channel protection is required for differential or single-ended signals in a DIP package. The low 1.5pF capacitance makes it suitable for high-frequency applications where signal distortion must be minimized. Verify that the 90V breakdown voltage provides sufficient margin for the specific system voltage levels.
