Product details
Overview
DS1100LU-300 from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 60ns (TAP 1), 120ns (TAP 2), 180ns (TAP 3), 240ns (TAP 4), and 300ns (TAP 5), operating from −40°C to +85°C in an 8-pin µMAX package. It reproduces both leading and trailing edges with equal precision and drives up to 10 LS-TTL loads per tap.
For engineers reviewing the DS1100LU-300 datasheet, DS1100LU-300 pinout, DS1100LU-300 application, or DS1100LU-300 equivalent, this device serves as a stable, all-silicon timing element for edge-aligned signal synchronization, clock deskewing, and pulse-width adjustment in high-reliability digital systems where hybrid delay lines are unsuitable.
Technical Context
The DS1100LU-300 implements a monolithic CMOS silicon delay line architecture with five fixed, equally spaced delay taps referenced to a single input. Each tap delivers deterministic propagation delay with ±4ns tolerance (for ≤40ns delays) or ±13% (for >40ns delays) over full temperature and voltage range (3.0V–3.6V, −40°C to +85°C).
It supports TTL-/CMOS-compatible logic levels (VIH ≥ 2.0V, VIL ≤ 0.8V), exhibits low active current (10mA typical at 1MHz), and features fast output rise/fall times (2.0–2.5ns), enabling precise edge alignment in high-speed digital interfaces without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures compatibility with 3.3V logic domains and robust operation across industrial voltage variation. |
| TAP 5 Delay | 300ns nominal - provides precise, fixed latency for time-critical signal alignment in test equipment or FPGA I/O conditioning. |
| Delay Tolerance | ±13% over −40°C to +85°C - guarantees predictable skew between taps under thermal stress without recalibration. |
| Output Drive | 8mA sink / −1mA source - directly interfaces with 74LS logic without buffer stages, reducing BOM count. |
| Input Pulse Width | ≥20% of TAP 5 delay (≥60ns) - defines minimum usable pulse duration to maintain delay accuracy. |
| Power-Up Time | 200μs - establishes maximum wait time before valid output after VCC stabilization. |
Pinout & Package
DS1100LU-300 is housed in an 8-pin µMAX package (outline U8+1, land pattern 90-0092), measuring 3mm × 3mm × 0.8mm, with exposed pad for thermal enhancement and RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input accepting TTL/CMOS-compatible signals; triggers all five delay paths simultaneously. |
| 2 | TAP 2 | Second delay output (120ns); electrically identical to other taps-no internal buffering or level-shifting. |
| 3 | TAP 4 | Fourth delay output (240ns); shares same drive strength and timing spec as TAP 1–5. |
| 4 | GND | Analog/digital ground reference; must be connected to low-impedance PCB plane for delay stability. |
| 5 | TAP 5 | Fifth and longest delay output (300ns); used for maximum latency insertion or coarse timing calibration. |
| 6 | TAP 3 | Third delay output (180ns); enables mid-range interpolation between TAP 2 and TAP 4 for multi-phase sampling. |
| 7 | TAP 1 | First delay output (60ns); shortest fixed latency path for fine-grained signal advancement or jitter reduction. |
| 8 | VCC | +3.3V supply input; requires local 0.1μF ceramic decoupling adjacent to pin for AC noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates aging drift and thermal hysteresis inherent in hybrid or SAW-based delay lines, ensuring long-term timing stability. |
| Leading- and trailing-edge accuracy | Enables bidirectional pulse shaping-critical for applications requiring matched rise/fall delay in clock recovery or data eye alignment. |
| Five equally spaced taps | Provides deterministic, linearly scalable delay steps (60ns increments) for multi-point timing analysis or distributed signal synchronization. |
| Vapor-phase and IR solderable | Supports standard reflow profiles without reliability risk, compatible with automated SMT assembly for high-volume production. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-300 | Same delay values and electrical specs, but in 8-pin SO (150-mil) package instead of µMAX. | Requires larger PCB footprint and different thermal profile; suitable for prototyping or legacy SO-only layouts. | Select when board space permits larger package or when SO-mounting infrastructure is already established. |
| ON Semiconductor MC100EP195MNR4G | Differential ECL inputs/outputs, 5V supply, higher speed (sub-ns resolution), but no native 3.3V operation or 300ns tap. | Targets RF/microwave timing; lacks integrated 300ns tap and requires level translation for 3.3V systems. | Select only for high-frequency differential signaling where DS1100LU-300's single-ended CMOS interface is insufficient. |
Compared with DS1100LZ-300 and MC100EP195MNR4G, the DS1100LU-300 uniquely combines compact µMAX packaging, guaranteed 300ns tap accuracy over industrial temperature, and direct 3.3V CMOS compatibility-making it optimal for space-constrained embedded timing where hybrid alternatives introduce reliability risk.

FAQ
What is the nominal delay of the fifth tap on the DS1100LU-300?
The DS1100LU-300 has a nominal TAP 5 delay of 300ns, as indicated by the "-300" suffix. This value is specified at +25°C and VCC = 3.3V, with ±13% tolerance over the full industrial temperature range (−40°C to +85°C) and supply voltage range (3.0V to 3.6V). All five taps scale linearly from TAP 1 (60ns) to TAP 5 (300ns) in 60ns increments.
Does the DS1100LU-300 support both rising and falling edge delay accuracy?
Yes, the DS1100LU-300 is explicitly designed to reproduce both leading and trailing edges with equal precision. Its datasheet confirms matched tPLH (rising) and tPHL (falling) delay tolerances across all taps, enabling accurate pulse-width preservation and bidirectional signal alignment critical in clock recovery and data eye optimization.
Can the DS1100LU-300 drive standard TTL loads directly?
Yes, each tap of the DS1100LU-300 can drive up to 10 74LS loads, verified under DC conditions (IOL = 8mA, IOH = −1mA). This capability eliminates the need for external buffers in most 3.3V logic interfacing scenarios, provided proper power supply decoupling and layout practices are followed per Maxim's application guidance.
What package type is used for the DS1100LU-300?
The DS1100LU-300 uses the 8-pin µMAX package (outline U8+1), a 3mm × 3mm surface-mount package with exposed thermal pad. It is RoHS-compliant (lead-free), vapor-phase and IR reflow compatible, and optimized for high-density PCB layouts where the larger SO-8 variant (DS1100LZ-300) is impractical.
Is the DS1100LU-300 suitable for automotive applications?
No, the DS1100LU-300 is rated for −40°C to +85°C operation and is not qualified to AEC-Q100 standards. While its temperature range overlaps with some automotive cabin applications, Maxim does not specify automotive-grade reliability testing, qualification, or extended lifetime data for the DS1100LU-300; it is intended for industrial, medical, and test equipment use.
