Product details
Overview
DS1110LE-125+ from Maxim Integrated is a 3V, 10-tap all-silicon delay line delivering precisely spaced 12.5ns increments (125ns total delay), ±5% or ±2ns accuracy at 3.3V/+25°C, TTL/CMOS-compatible I/O, and operation from −40°C to +85°C in a 14-pin TSSOP package. It serves as a fixed-time signal alignment element in high-speed digital timing paths.
For engineers reviewing the DS1110LE-125+ datasheet, DS1110LE-125+ pinout, DS1110LE-125+ application, or DS1110LE-125+ equivalent, key selection criteria include tap spacing resolution (12.5ns), leading/trailing-edge delay symmetry, supply voltage range (2.7V–3.6V), output drive capability (10 × 74LS loads), and industrial temperature support.
Technical Context
The DS1110LE-125+ implements a monolithic silicon delay chain with 10 equally spaced taps derived from a single input edge-triggered path. Each tap reproduces both rising and falling edges with matched propagation characteristics, enabling precise skew control in synchronous logic interfaces.
Delay values are factory-trimmed for ±5% or ±2ns tolerance (whichever greater) at 3.3V and +25°C, with unidirectional drift across temperature and supply voltage-ensuring monotonic relative tap behavior. Input pulse width must exceed 10ns for reliable tap activation per AC specifications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total Delay | 125ns - fixed end-to-end propagation time from IN to TAP10, enabling deterministic signal alignment in clock/data recovery paths |
| Tap Spacing | 12.5ns - uniform interval between consecutive taps, supporting fine-grained timing adjustment in test instrumentation and serializer/deserializer circuits |
| Delay Accuracy | ±5% or ±2ns (greater) at 3.3V/+25°C - guarantees worst-case timing margin for setup/hold validation in high-speed digital systems |
| Supply Range | 2.7V to 3.6V - compatible with modern 3.3V logic domains and tolerant of rail variation in noisy industrial environments |
| Operating Temp | −40°C to +85°C - qualified for use in automated test equipment, medical diagnostics, and industrial communications hardware |
| Output Drive | 10 × 74LS loads - sufficient fanout to interface directly with legacy TTL logic without buffering in mixed-voltage systems |
| Input Capacitance | 5–10pF - low capacitive loading preserves signal integrity on high-frequency input traces and minimizes reflection risk |
Pinout & Package
DS1110LE-125+ is housed in a 14-pin Thin Shrink Small Outline Package (TSSOP), 173mil body width, lead pitch 0.65mm, compliant with JEDEC MO-153. The package supports vapor-phase and IR reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended CMOS/TTL-compatible input; accepts 0–3.3V logic transitions with ≤2ns rise/fall time |
| 2 | N.C. | No internal connection; must be left floating or grounded per layout best practices to avoid parasitic coupling |
| 3–12 (in order) | TAP1–TAP10 | 10 delay outputs spaced at 12.5ns intervals; each provides full-rail logic-level copies of IN with matched rising/falling delays |
| 13 | GND | Dedicated ground reference for internal delay chain and output drivers; requires low-inductance PCB connection |
| 14 | VCC | Power supply input (2.7V–3.6V); bypassing with 0.1µF ceramic capacitor near pin is mandatory for stable delay performance |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates quartz or analog RC-based drift; ensures long-term stability and shock/vibration immunity in portable medical devices |
| Leading- and trailing-edge precision | Enables accurate pulse-width preservation across all taps-critical for PWM synchronization and clock-domain crossing |
| Low-power CMOS operation | Typical active current <150mA at max frequency; reduces thermal load in dense ATE backplanes and embedded controllers |
| TTL/CMOS compatibility | Direct interfacing with 74LS, 74HC, and FPGA I/O banks without level-shifting circuitry in mixed-logic systems |
| Industrial temperature qualification | Guaranteed parametric performance across −40°C to +85°C-validates use in outdoor telecom infrastructure and factory-floor automation |

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 |
|---|---|---|---|
| DS1110SE-125+ | 5V supply only (4.5V–5.5V); same 125ns total delay, 12.5ns tap spacing, and ±5%/±2ns accuracy | Requires 5V rail; incompatible with 3.3V-only systems; otherwise identical timing behavior and pinout | Select when legacy 5V logic infrastructure is present and no mixed-voltage design constraints exist |
| MAX9602EUA+ | Programmable 8-tap delay (1–100ns range, 1ns step); 3.3V operation; SPI-configurable; higher power and cost | Offers dynamic reconfiguration but lacks guaranteed tap-to-tap monotonicity and industrial temp grade | Choose only when field-adjustable delay resolution is mandatory and budget allows for added complexity |
Compared with DS1110SE-125+, DS1110LE-125+ enables direct integration into 3.3V systems without level translation; compared with MAX9602EUA+, it delivers lower-cost, zero-configuration, and thermally robust timing alignment where fixed delays suffice.

FAQ
What is the exact delay value from IN to TAP10 for DS1110LE-125+?
The DS1110LE-125+ provides a nominal total delay of 125ns from the IN pin to the TAP10 output, with a tolerance of ±5% or ±2ns (whichever is greater) at 3.3V and +25°C. This value is factory-trimmed and applies to both rising and falling edges, ensuring symmetrical timing behavior critical for pulse-width preservation in digital control loops.
Does DS1110LE-125+ support operation at 2.5V supply?
No, DS1110LE-125+ is characterized and guaranteed only for operation between 2.7V and 3.6V. At 2.5V, timing parameters-including delay accuracy, output drive strength, and input threshold levels-are not specified and may fall outside datasheet limits, risking functional failure in production systems.
Can DS1110LE-125+ drive 50Ω transmission lines directly?
No, DS1110LE-125+ is rated to drive up to 10 × 74LS loads (≈450Ω || 15pF), not 50Ω coaxial lines. Driving 50Ω loads directly causes excessive current draw, signal distortion, and potential output stage damage. A dedicated line driver or impedance-matching buffer is required for such applications.
Is the pinout of DS1110LE-125+ identical to DS1110SE-125+?
Yes, DS1110LE-125+ and DS1110SE-125+ share identical 14-pin TSSOP pinouts and terminal functions-including IN, GND, VCC, N.C., and TAP1–TAP10 positions-enabling mechanical compatibility. However, electrical substitution requires verifying system-level voltage compliance, as DS1110SE-125+ operates only at 5V.
What is the maximum input frequency supported by DS1110LE-125+?
DS1110LE-125+ does not specify a hard maximum frequency, but AC characterization requires input pulse widths ≥10ns and periods ≥2×pulse width. For reliable operation, input frequencies should remain below ~50MHz (20ns period) to ensure adequate pulse width and avoid timing ambiguity across taps, especially under temperature and voltage extremes.
