100 ns tapped delay line in 8-uMAX
The Maxim Integrated DS1100LU-100+ is a nonprogrammable silicon delay line that provides five equally spaced taps from a single input, with a total delay of 100 ns and a tap increment of 20 ns. It operates from a 3V to 3.6V supply over the industrial temperature range of -40°C to 85°C, making it a direct fit for 3.3V logic timing alignment in motor drives, industrial controllers, and telecom line cards where a fixed, repeatable delay is needed without external RC components.
Five taps at 20 ns increments — what that buys you
The five taps give you delay points at 20 ns, 40 ns, 60 ns, 80 ns, and 100 ns from the input. For a designer aligning clock-to-data skew on a parallel bus or generating a precise pulse-width window, the 20 ns resolution is the key parameter — it sets the smallest timing adjustment you can make without external trim. The nonprogrammable nature means the delay is fixed at manufacture; there is no adjustment pin or digital interface, so the part is a drop-in for production where the timing budget is already settled.
3.3V supply and industrial temperature range
Rated for 3V to 3.6V, the DS1100LU-100+ runs directly from a 3.3V rail without a separate regulator. The -40°C to 85°C operating range covers factory-floor and outdoor cabinet environments. The 8-uMAX/uSOP package (3.00 mm width) fits tight PCB layouts where board area is at a premium.
Active production — no last-time-buy pressure
The DS1100LU-100+ carries an active lifecycle status from Maxim Integrated, with no announced end-of-life or last-time-buy window. It is ROHS3 compliant. For a BOM line that needs a fixed 100 ns delay, this part is a stable, in-production choice without the sourcing risk of an obsolete timing component.
