Product details
Overview
DS1110LE-250+ from Maxim Integrated is a 3V, 10-tap all-silicon delay line delivering precisely spaced 25ns increments (250ns total delay), ±5% or ±2ns accuracy at 3.3V/+25°C, TTL/CMOS-compatible input/output, and stable leading- and trailing-edge timing for signal alignment in high-speed digital systems.
For engineers reviewing the DS1110LE-250+ datasheet, DS1110LE-250+ pinout, DS1110LE-250+ application, or DS1110LE-250+ equivalent, this page provides verified electrical specs, tap-specific delay behavior, TSSOP-14 package integration guidance, and real-world use cases in communications synchronization and ATE stimulus timing.
Technical Context
The DS1110LE-250+ implements a monolithic CMOS delay chain with 10 fixed-output taps derived from a single input edge, supporting both rising- and falling-edge propagation with matched tolerance. It operates across 2.7V–3.6V supply and -40°C to +85°C, with delay variation tightly coupled across taps under voltage/temperature shifts.
Each tap delivers logic-level output capable of driving up to 10 LS-TTL loads, and delay accuracy is specified per tap relative to nominal values-e.g., Tap 1 = 25ns, Tap 10 = 250ns-with initial tolerance defined at 3.3V/+25°C and derated over full range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total Delay | 250ns nominal; enables precise inter-signal timing alignment in clock/data recovery paths |
| Delay per Tap | 25ns uniform increment; supports multi-phase sampling or staggered trigger generation |
| Delay Accuracy | ±5% or ±2ns (whichever greater) at 3.3V/+25°C; ensures predictable setup/hold margin in synchronous designs |
| Supply Range | 2.7V to 3.6V; compatible with modern 3V logic families without level-shifting |
| Operating Temp | -40°C to +85°C; validated for industrial-grade embedded and test equipment deployment |
| Input Compatibility | TTL/CMOS logic levels; interfaces directly with FPGA I/O, microcontroller GPIO, and ASIC drivers |
| Output Drive | 12mA sink / 1mA source at VCC = 2.7V; sufficient for fanout to multiple LS-TTL inputs |
Pinout & Package
DS1110LE-250+ is housed in a 14-pin thin shrink small-outline package (TSSOP, 173mil width), with exposed pad not electrically connected. Pin 2 is no-connect; all other pins are assigned per functional role below.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input; accepts TTL/CMOS pulses with ≤2ns rise/fall time |
| 2 | N.C. | No internal connection; must be left floating or tied to GND per layout best practice |
| 3–12, 13, 14, 7, 8, 9, 10, 11 | TAP1–TAP10 | Fixed-delay outputs (25ns–250ns); each drives independent load without crosstalk |
| 14 | VCC | Primary power supply (2.7V–3.6V); requires local 0.1µF ceramic decoupling |
| 7 | GND | Digital ground reference; connects to system ground plane with low-inductance path |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates external RC networks and trim components; improves long-term stability vs. analog delay solutions |
| Leading- and trailing-edge matching | Ensures symmetrical delay for both edges-critical for pulse-width preservation in timing-critical paths |
| 10 equally spaced taps | Enables flexible tap selection without interpolation; simplifies PCB routing and reduces skew between outputs |
| Low-power CMOS operation | Typical active current <150mA at max frequency; suitable for battery-backed or thermally constrained systems |
| Vapor-phase and IR solderable | Supports standard reflow profiles per J-STD-020A; eliminates manual soldering risk in high-volume assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-tap delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1110LE-200+ | 200ns total delay, 20ns/tap; identical accuracy, supply, and package | Suitable where shorter overall latency is required without changing tap count or interface | Select when system timing budget allows 50ns less delay than DS1110LE-250+ |
| DS1110LE-300+ | 300ns total delay, 30ns/tap; same tolerance, temperature range, and drive capability | Preferred for longer inter-signal spacing needs, e.g., wider clock/data eye openings | Choose when DS1110LE-250+ undershoots required delay margin by ≥50ns |
Compared with DS1110LE-200+ and DS1110LE-300+, the DS1110LE-250+ offers the optimal balance of granularity (25ns/tap) and total span (250ns) for mid-range timing alignment tasks-neither over-constraining nor under-providing delay headroom in industrial control and instrumentation designs.

FAQ
What is the nominal delay accuracy of DS1110LE-250+ at room temperature?
The DS1110LE-250+ guarantees ±5% or ±2ns delay accuracy-whichever is greater-at 3.3V and +25°C. This applies to all 10 taps, including Tap 1 (25ns) and Tap 10 (250ns), and reflects initial tolerance before temperature/voltage derating. The device maintains matched leading- and trailing-edge precision within this band.
Can DS1110LE-250+ operate outside the 3.3V supply condition specified for accuracy?
Yes, DS1110LE-250+ functions across 2.7V–3.6V, but delay values shift predictably with supply voltage-e.g., ~0.1% change per 10mV near 3.3V. Full accuracy specs apply only at 3.3V/+25°C; operation at 2.7V or 3.6V requires referencing the voltage vs. delay curves in the datasheet for design margining.
How many loads can each tap of DS1110LE-250+ drive reliably?
Each tap of DS1110LE-250+ is rated to drive up to 10 LS-TTL loads (equivalent to 450Ω || 15pF). This drive strength is maintained across the full operating temperature and voltage range, enabling direct interfacing with legacy logic families without buffer amplification.
Is DS1110LE-250+ pin-compatible with other DS1110L variants?
Yes, DS1110LE-250+ shares identical 14-pin TSSOP pinout and function mapping with all DS1110L-series parts (e.g., DS1110LE-100+, DS1110LE-500+). Only the total delay and per-tap spacing differ; no PCB layout changes are needed when substituting within the family for timing optimization.
Does DS1110LE-250+ require external passive components for basic operation?
No, DS1110LE-250+ is a fully self-contained silicon delay line requiring only VCC decoupling (0.1µF ceramic) and proper grounding. No resistors, capacitors, or trimming elements are needed-unlike RC-based or programmable delay solutions-reducing BOM count and layout complexity.
