Product details
Overview
DS1100U-250+T from Maxim Integrated is a 5-tap silicon delay line IC providing fixed, equally spaced delays of 50ns, 100ns, 150ns, 200ns, and 250ns at 5V supply. It reproduces both leading and trailing edges with ±4ns tolerance over -40°C to +85°C, drives up to 10 LS-TTL loads per tap, and is housed in an 8-pin µMAX package. It serves as a precision timing element in digital signal alignment, clock deskewing, and pulse-width adjustment circuits.
For engineers reviewing the DS1100U-250+T datasheet, DS1100U-250+T pinout, DS1100U-250+T application, or DS1100U-250+T equivalent, key selection criteria include tap delay accuracy across temperature, TTL/CMOS compatibility, low-power CMOS operation, 5V supply requirement, and µMAX package footprint constraints for high-density PCB layouts.
Technical Context
The DS1100U-250+T implements an all-silicon delay architecture with five fixed-output taps derived from a monolithic delay chain. Each tap delivers identical propagation characteristics for rising and falling edges, with delay tolerance specified as ±4ns (for ≤40ns delays) or ±13% (for >40ns delays) over full industrial temperature range.
It operates exclusively at 5V (4.75V–5.25V), draws 30–50mA active current, and features input capacitance of 5–10pF. The device supports vapor-phase, IR, and wave soldering, and requires no external components-functioning as a self-contained, single-supply timing element with no configuration interface or control pins.

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100Z-250+ | Same electrical specs and delay values, but in 8-pin SO (150-mil) package instead of µMAX | Better suited for through-hole prototyping or legacy SO footprints; larger board area and higher thermal resistance | Select DS1100Z-250+ when µMAX assembly capability is unavailable or SO footprint is already committed |
| MAX9601EUA+ | Single-output, adjustable delay (0–250ns) with 10ps resolution; requires external control interface and power supply sequencing | Used where dynamic delay tuning is required; not drop-in compatible due to different pin count, interface, and supply requirements | Select MAX9601EUA+ only when programmable delay and fine resolution outweigh fixed-tap simplicity and zero-config operation |
Compared with DS1100Z-250+ and MAX9601EUA+, the DS1100U-250+T offers the smallest PCB footprint and simplest integration for static, multi-tap delay needs-ideal for space-constrained industrial controllers and embedded instrumentation where fixed delays suffice.

FAQ
What is the nominal delay value for each tap of the DS1100U-250+T?
The DS1100U-250+T provides five equally spaced delays: TAP1 = 50ns, TAP2 = 100ns, TAP3 = 150ns, TAP4 = 200ns, and TAP5 = 250ns. These values are specified at +25°C and 5V, with tolerances tightened to ±4ns over the full -40°C to +85°C operating range. All delays are measured at the 1.5V logic threshold for both rising and falling edges.
Does the DS1100U-250+T require external components or configuration?
No, the DS1100U-250+T is a fully self-contained delay line requiring only a 5V supply and ground connection. It has no control pins, registers, or external timing components. A 0.1µF ceramic capacitor is recommended near the VCC pin for supply decoupling, but no resistors, capacitors, or clocks are needed for basic operation of the DS1100U-250+T.
Can the DS1100U-250+T drive standard TTL loads directly?
Yes, each tap of the DS1100U-250+T can drive up to 10 LS-TTL loads (equivalent to 74LS inputs) without external buffering. Its output drive strength is specified as 12mA sink and -1mA source at VCC = 4.75V, ensuring robust logic-level compatibility and noise margin in mixed-logic systems using the DS1100U-250+T.
Is the DS1100U-250+T compatible with lead-free reflow processes?
Yes, the "+T" suffix in DS1100U-250+T indicates a lead(Pb)-free, RoHS-compliant µMAX package qualified for lead-free reflow soldering up to +260°C peak temperature. The device supports vapor-phase, infrared, and wave soldering per JEDEC J-STD-020, making it suitable for modern high-volume SMT assembly lines using the DS1100U-250+T.
How does delay accuracy vary with temperature for the DS1100U-250+T?
For the DS1100U-250+T, delay accuracy over temperature is specified as ±4ns for all taps across -40°C to +85°C. This applies to the absolute delay value-not percentage-because all taps exceed 40ns. Delay shifts are unidirectional: if one tap slows with temperature, all others slow proportionally, preserving relative spacing and monotonicity in the DS1100U-250+T's output timing.
