256-tap programmable delay line in 16-SOIC
The DS1023S-25+ is a single-channel 1-Shot programmable delay line from Analog Devices, offering 256 taps with a 250 ps tap increment and a total delay range of 63.75 ns. The first tap delay is 16.5 ns, giving you fine-grained control over timing edges in a 5 V ±5% supply system. Housed in a 16-SOIC wide-body package (0.295", 7.50 mm width), this part is surface-mount and ships in Tube format — not tape-and-reel, so factor that into your pick-and-place setup if you're running high-volume reels.
Timing resolution and supply rail fit
With a 250 ps tap increment and 256 steps, the DS1023S-25+ gives you 8-bit resolution across the 47.25 ns programmable window (63.75 ns total minus the 16.5 ns first-tap offset). That's tight enough for deskewing parallel data buses or trimming pulse widths in timing-critical signal chains.
RoHS3 compliant, meeting current EU exemption rules without lead or restricted substances. If you're looking for a drop-in alternative, the parametric space (256 taps, 250 ps increment, 16-SOIC) is narrow enough that a direct cross-reference would require board-level validation.
