Product details
Overview
DS1110LE-300+ from Maxim Integrated is a 3V, 10-tap all-silicon delay line delivering precisely spaced 30ns increments (300ns total delay), ±5% or ±2ns accuracy at 3.3V/+25°C, TTL/CMOS-compatible, and operating from -40°C to +85°C in a 14-pin TSSOP package for timing alignment in high-speed digital interfaces.
For engineers reviewing the DS1110LE-300+ datasheet, DS1110LE-300+ pinout, DS1110LE-300+ application, or DS1110LE-300+ equivalent, key selection criteria include tap spacing tolerance, leading/trailing-edge delay matching, supply voltage range (2.7V–3.6V), output drive capability (10 × 74LS loads), and industrial temperature operation.
Technical Context
The DS1110LE-300+ implements a monolithic silicon delay chain with fixed propagation stages, producing 10 deterministic, equally spaced output taps-TAP1 through TAP10-each offset by exactly 30ns. Delay stability is maintained across voltage (2.7V–3.6V) and temperature (-40°C to +85°C) via matched transistor design.
All taps reproduce both rising and falling edges with identical precision; delay variation is unidirectional-e.g., if TAP1 slows with temperature, all other taps slow proportionally. Input pulse width must be ≥10ns (per Table 1), and outputs are specified with 15pF load and 450Ω parallel termination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total Delay | 300ns nominal; enables precise clock/data phase alignment in serial link receivers and test pattern generators. |
| Tap Spacing | 30ns per tap; supports fine-grained timing adjustment for skew compensation in parallel bus systems. |
| Delay Accuracy | ±5% or ±2ns (whichever greater) at 3.3V/+25°C; ensures predictable setup/hold margin in synchronous logic. |
| Supply Range | 2.7V to 3.6V; compatible with modern 3.3V LVTTL and mixed-voltage I/O domains. |
| Operating Temp | -40°C to +85°C; validated for industrial-grade embedded control and automated test equipment. |
| Output Drive | 12mA sink / 1mA source at VCC = 2.7V; sufficient to directly drive 10 × 74LS inputs without buffering. |
| Input Capacitance | 5–10pF typical; minimizes signal reflection and loading on high-speed clock distribution traces. |
Pinout & Package
Package: 14-pin TSSOP (173mil body width), lead-free and RoHS-compliant, vapor-phase and IR solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended CMOS/TTL input; accepts 0–3.3V logic with 5–10pF capacitance and <1µA leakage. |
| 2 | N.C. | No internal connection; must remain unconnected to avoid parasitic coupling or ESD path disruption. |
| 3–12 (even) | TAP1, TAP3, TAP5, TAP7, TAP9 | Odd-numbered delay taps; TAP1 = 30ns, TAP3 = 90ns, etc., each with matched rise/fall delay. |
| 4–13 (odd) | TAP2, TAP4, TAP6, TAP8, TAP10 | Even-numbered delay taps; TAP2 = 60ns, TAP4 = 120ns, up to TAP10 = 300ns. |
| 7 | GND | Dedicated ground reference; must be low-inductance connected to system ground plane for delay stability. |
| 14 | VCC | Power supply input; requires local 0.1µF ceramic decoupling within 5mm of pin for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates external RC networks and trim components; guarantees monotonic delay vs. temperature. |
| Leading- and trailing-edge matching | Enables accurate pulse-width preservation in delay-sensitive applications like strobe generation. |
| 10-tap equal spacing | Provides deterministic, repeatable delay steps-no interpolation or calibration required. |
| Low-power CMOS | Typical active current ≤40mA at 1MHz; reduces thermal drift and simplifies power delivery. |
| TTL/CMOS compatibility | Accepts standard logic thresholds (VIH ≥2.2V, VIL ≤0.8V); interoperable with legacy and modern logic families. |

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-250+ | 250ns total delay, 25ns/tap; otherwise identical electrical specs, pinout, and package. | Suitable where shorter overall delay is acceptable and finer 25ns granularity is preferred over 30ns. | Select DS1110LE-250+ only when system timing budget permits 50ns less total delay and tighter tap resolution improves margin. |
| DS1110LE-350+ | 350ns total delay, 35ns/tap; same temperature range, supply, and drive capability. | Used when longer delay headroom is needed-for example, in systems with higher interconnect latency or slower logic families. | Choose DS1110LE-350+ if board-level propagation delays exceed 300ns and additional margin is required for worst-case PVT. |
Compared with DS1110LE-250+ and DS1110LE-350+, the DS1110LE-300+ provides optimal balance of delay headroom and tap resolution for mid-range timing alignment tasks-neither over-provisioning nor constraining system-level skew budgets.

FAQ
What is the exact delay value per tap for DS1110LE-300+?
The DS1110LE-300+ delivers exactly 30ns per tap, with TAP1 at 30ns, TAP2 at 60ns, and so on up to TAP10 at 300ns. This 30ns increment is guaranteed by design and verified across -40°C to +85°C and 2.7V–3.6V supply. The DS1110LE-300+ datasheet Table 1 explicitly defines this spacing as nominal and confirmed under standard test conditions.
Does DS1110LE-300+ support both rising and falling edge delays with equal accuracy?
Yes, the DS1110LE-300+ reproduces both leading and trailing edges with identical precision-its delay tolerance of ±5% or ±2ns applies equally to tPLH and tPHL measurements. This symmetry is achieved through matched internal transistor paths and is validated in the DS1110L family's AC Electrical Characteristics table and Typical Operating Characteristics plots.
Can DS1110LE-300+ operate reliably at 2.7V supply?
Yes, the DS1110LE-300+ is fully characterized from 2.7V to 3.6V. At 2.7V, it maintains full functionality-including all 10 taps, specified delay accuracy, and output drive (12mA sink)-as confirmed in the DC Electrical Characteristics table. Active current remains below 150mA, and timing parameters retain their published tolerances.
Is DS1110LE-300+ pin-compatible with other DS1110L variants?
Yes, all DS1110L variants-including DS1110LE-300+-share identical 14-pin TSSOP pinout, supply, ground, input, and tap assignments. No PCB redesign is needed when substituting between DS1110LE-100+ through DS1110LE-500+; only the total delay and tap spacing change, with no effect on connectivity or layout.
What is the maximum capacitive load each tap of DS1110LE-300+ can drive?
Each tap of the DS1110LE-300+ is rated to drive up to 15pF capacitive load while maintaining specified delay accuracy and edge fidelity, as defined in the Test Setup Description and Output section. This matches the standard 74LS load (450Ω || 15pF), and the device supports driving 10 such loads simultaneously without degradation.
