What this delay line does on your board
The Maxim DS1100LZ-200+ is a nonprogrammable silicon delay line that gives you 5 equally spaced taps from a single input, with a total delay of 200 ns and a tap increment of 40 ns. It runs on a 3V to 3.6V supply, so it sits comfortably on a 3.3V rail alongside standard logic. The 8-SOIC package is surface-mount, and the part is rated for -40°C to 85°C, which covers most industrial and outdoor telecom gear. No programming, no external timing components — just route the input and pick the tap that matches your timing budget.
Lifecycle and sourcing reality
The DS1100LZ-200+ is listed as Active and ROHS3 compliant. No end-of-life notice, no last-time-buy clock ticking. That means you can qualify it into a new design without worrying about a sudden PCN.
Field-fit notes
8-SOIC with 0.154-inch body width — standard footprint, no surprises for the pick-and-place. Surface-mount means you need a reflow station or hot-air tool for a field swap; it is not socketed, so plan for that if you are doing on-site repairs. The part is nonprogrammable, so orientation is the only thing to get right: pin 1 marking on the SOIC is clear enough to read with a headlamp. No ESD sensitivity beyond the usual CMOS handling — keep it in the tube until you place it.
