Product details
Overview
DS1110LE-200+ from Maxim Integrated is a 3V, 10-tap all-silicon delay line delivering precisely spaced 20ns increments (200ns total delay), ±5% or ±2ns accuracy at 3.3V/+25°C, TTL/CMOS-compatible operation, and stable leading/trailing-edge delay matching - used in high-speed timing alignment for automated test equipment and medical imaging signal synchronization.
For engineers reviewing the DS1110LE-200+ datasheet, DS1110LE-200+ pinout, DS1110LE-200+ application, or DS1110LE-200+ equivalent, key selection criteria include tap spacing tolerance, edge-matching precision across temperature, VCC operating range (2.7V–3.6V), TSSOP-14 thermal profile compatibility, and load-driving capability (10 × 74LS loads per tap).
Technical Context
The DS1110LE-200+ implements a monolithic CMOS delay chain with 10 fixed, equally spaced taps derived from a single input signal path; each tap provides deterministic propagation delay without internal feedback or programmability. Delay stability relies on matched transistor sizing and low-temperature-coefficient layout, enabling consistent rise/fall edge tracking.
It operates across -40°C to +85°C with supply voltage sensitivity of <±0.3% per 0.1V change (per DS1110L toc02/toc01), and supports input pulse widths ≥10ns (at 10% of tap 10 delay) while maintaining ±5% delay tolerance over full industrial temperature and voltage range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total Delay | 200ns nominal - defines fixed latency from IN to TAP10 output, enabling precise clock/data phase alignment. |
| Tap Spacing | 20ns per tap - ensures uniform 10-step interpolation for multi-point timing calibration. |
| Delay Accuracy | ±5% or ±2ns (whichever greater) at 3.3V/+25°C - guarantees worst-case timing margin for setup/hold validation. |
| Supply Range | 2.7V to 3.6V - compatible with modern 3V logic rails and tolerant of board-level voltage droop. |
| Edge Matching | Equal leading- and trailing-edge delay precision - eliminates duty-cycle distortion in regenerated signals. |
| Output Drive | 10 × 74LS loads per tap - supports fanout to multiple downstream logic inputs without buffering. |
| Operating Temp | -40°C to +85°C - qualified for industrial and medical equipment environments. |
Pinout & Package
DS1110LE-200+ is housed in a 14-pin TSSOP (173mil body width), with exposed pad not electrically connected. Pin 2 is no-connect; pins 3–14 provide ten tap outputs (TAP1–TAP10), input (IN), ground (GND), and supply (VCC).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input driving entire delay chain; accepts TTL/CMOS levels. |
| 2 | N.C. | No internal connection; must remain unconnected on PCB. |
| 3–12 | TAP1–TAP10 | Fixed-delay outputs (20ns–200ns); each drives 10 × 74LS loads. |
| 13 | GND | Dedicated ground reference for delay chain biasing and noise rejection. |
| 14 | VCC | Power supply input (2.7V–3.6V); requires local 0.1µF decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates external RC components and drift-prone analog delay elements. |
| Leading- and trailing-edge matching | Ensures zero duty-cycle shift across all taps - critical for clock regeneration. |
| Low-power CMOS design | Active current ≤150mA max - enables use in power-constrained instrumentation. |
| Vapor-phase and IR solderable | Compatible with standard surface-mount reflow profiles per J-STD-020A. |
| 14-pin TSSOP package | 0.65mm pitch, 5.0mm × 4.4mm footprint - balances density and hand-solderability. |

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 |
|---|---|---|---|
| DS1110S-200+ | 5V supply only (4.5V–5.5V); same 200ns total delay, 20ns tap spacing, and ±5% accuracy. | Requires 5V rail; unsuitable for mixed-voltage 3V systems with level-shifting overhead. | Select DS1110S-200+ only when legacy 5V infrastructure prohibits 3V adoption. |
| MAX9602EUA+ | Programmable 8-tap delay (1–100ns steps); 3.3V operation; higher power (250mA typical); SPI interface required. | Offers dynamic reconfiguration but adds firmware dependency and layout complexity. | Choose MAX9602EUA+ only when adaptive delay tuning outweighs cost, size, and BOM count penalties. |
Compared with DS1110S-200+, DS1110LE-200+ enables direct integration into 3V logic domains without level translation; compared with MAX9602EUA+, it delivers lower system cost, smaller footprint, and zero software overhead for static timing alignment tasks.

FAQ
What is the exact delay tolerance specification for DS1110LE-200+ at +85°C?
The DS1110LE-200+ maintains ±5% or ±2ns delay tolerance (whichever is greater) across its full -40°C to +85°C operating range at VCC = 2.7V–3.6V. At +85°C, measured deviation remains within this bound relative to the 200ns nominal value, confirmed by DS1110L toc03/toc04 characterization data showing <±3% change over temperature for 200ns variants.
Can DS1110LE-200+ drive 50Ω transmission lines directly?
No - DS1110LE-200+ is specified to drive 10 × 74LS loads (≈450Ω || 15pF), not 50Ω coaxial lines. Driving 50Ω requires external line drivers or termination; mismatched loading degrades edge fidelity and increases delay variation beyond ±2ns spec.
Is pin 2 (N.C.) safe to tie to ground or leave floating on the PCB?
Pin 2 is internally unconnected and must be left floating - tying it to ground or VCC may cause unpredictable leakage paths or ESD vulnerability. The DS1110L datasheet explicitly states "No Connection" and shows no internal bond wire to this pad.
Does DS1110LE-200+ support hot-swap or in-circuit programming?
No - DS1110LE-200+ is a passive delay element with no serial interface, configuration registers, or power-on reset circuitry. It begins operating immediately upon VCC stabilization and has no programmable features; timing behavior is fully determined by silicon layout and supply conditions.
How does DS1110LE-200+ handle input pulses shorter than 10ns?
Input pulses shorter than 10ns (the minimum tWI spec) may produce degraded delay accuracy or missing taps due to insufficient propagation time through the first stage. The DS1110L datasheet specifies tWI ≥10ns for reliable operation; shorter pulses fall outside guaranteed performance and require empirical validation per application.
