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 across -40°C to +85°C, driving up to 10 LS-TTL loads per tap, and housed in an 8-pin µMAX package.
For engineers reviewing the DS1100LU-300+ datasheet, DS1100LU-300+ pinout, DS1100LU-300+ application, or DS1100LU-300+ equivalent, this page delivers verified timing accuracy, edge-preserving delay behavior, TTL/CMOS compatibility, low-power CMOS operation, and industrial-temperature stability - all critical for digital synchronization, clock deskew, and pulse shaping in embedded control and test instrumentation.
Technical Context
The DS1100LU-300+ implements a fully silicon-based delay architecture with five fixed, equally spaced output taps, reproducing both leading and trailing edges with matched precision at 1.5V switching thresholds. Its delay tolerance is ±4ns (for ≤40ns taps) or ±13% (for >40ns taps) over full temperature and voltage range.
Each tap delivers rail-to-rail CMOS/TTL-compatible outputs with 2.0–2.5ns rise/fall times, 8mA sink / -1mA source drive capability, and operates from 3.0V to 3.6V supply. Input pulse width must exceed 20% of TAP 5 delay (i.e., ≥60ns) for guaranteed timing accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures stable operation in 3.3V systems with ±10% rail variation. |
| Nominal Delays | TAP 1: 60ns, TAP 2: 120ns, TAP 3: 180ns, TAP 4: 240ns, TAP 5: 300ns - enables precise multi-stage timing alignment without external components. |
| Delay Tolerance | ±13% over -40°C to +85°C - guarantees predictable skew between stages in industrial environments. |
| Output Drive | 8mA sink / -1mA source - directly interfaces with 74LS logic without buffering. |
| Rise/Fall Time | 2.0ns to 2.5ns - supports clean signal integrity at high-speed digital edges. |
| Operating Temp | -40°C to +85°C - qualified for automotive under-hood and industrial control applications. |
Pinout & Package
DS1100LU-300+ uses the 8-pin µMAX package (outline U8+1), 3mm × 3mm body, 0.65mm pitch, RoHS-compliant lead-free construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Digital input accepting TTL/CMOS logic levels; triggers all five delay taps simultaneously. |
| 2 | TAP 2 | Second delayed output (120ns); provides intermediate timing reference for pipeline staging. |
| 3 | TAP 4 | Fourth delayed output (240ns); enables coarse-fine delay partitioning in pulse-width modulation circuits. |
| 4 | GND | Ground reference for all internal circuitry and output drivers; requires low-impedance PCB connection. |
| 5 | TAP 5 | Fifth delayed output (300ns); longest delay stage used for system-level timing margining or echo cancellation. |
| 6 | TAP 3 | Third delayed output (180ns); central tap for symmetric delay splitting in clock recovery paths. |
| 7 | TAP 1 | First delayed output (60ns); shortest delay for minimal latency insertion or jitter filtering. |
| 8 | VCC | +3.3V supply input; requires local 0.1µF ceramic decoupling adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay line | Eliminates hybrid component drift and aging; delivers stable delay over 10+ years in continuous operation. |
| Equal-edge precision | Matches leading/trailing edge delays within ±2ns - essential for duty-cycle preservation in clock distribution. |
| Five fixed taps | Provides deterministic, non-programmable delay points - avoids configuration overhead and firmware dependencies. |
| 74LS load drive | Drives ten LS-TTL inputs per tap without external buffers - reduces BOM count and board area in legacy logic designs. |
| Vapor-phase/IR solderable | Compatible with standard reflow profiles including Pb-free (260°C) - supports high-yield automated assembly. |
Applications
| Digital Test Equipment | Pulse Width Modulation Control |
|---|---|
Use Scenario: Generating calibrated time intervals for oscilloscope trigger calibration and logic analyzer timing verification. IC Role / Device Role / Timing Role: Fixed-delay reference generator providing traceable, repeatable edge offsets across five synchronized outputs. Use Value: Enables sub-nanosecond measurement repeatability without FPGA-based delay synthesis or analog RC networks. | Use Scenario: Introducing controlled dead-time between high-side and low-side gate signals in motor driver half-bridges. IC Role / Device Role / Timing Role: Hardware-based delay element ensuring shoot-through prevention via deterministic propagation delay. Use Value: Guarantees minimum 60ns–300ns dead-time windows independent of MCU clock jitter or software latency. |
| Digital Signal Synchronization | Legacy Logic Interface Timing |
Use Scenario: Aligning asynchronous data streams from multiple sensors before feeding into a common FIFO or DSP core. IC Role / Device Role / Timing Role: Tap-selectable skew compensator matching path delays across parallel data lanes. Use Value: Achieves <100ps inter-tap skew matching across temperature, eliminating need for dynamic deskew calibration. | Use Scenario: Interfacing modern microcontrollers with older 74LS-based peripheral logic requiring precise setup/hold timing margins. IC Role / Device Role / Timing Role: Delay-insertion buffer preserving signal integrity while meeting LS-TTL timing requirements. Use Value: Provides guaranteed 8mA drive and 2.5ns edge fidelity - replaces discrete resistor-capacitor delay networks with higher reliability. |
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 |
|---|---|---|---|
| DS1023-300+ (Maxim) | 3-tap version (30ns/60ns/300ns); no TAP 2 or TAP 4; same µMAX package and 3.3V operation. | Limited to three delay points; insufficient for 5-stage pipeline or multi-point timing calibration. | Select when only coarse delay steps are needed and board space is constrained. |
| 74LVC1G123DBVR (TI) | Single monostable multivibrator; programmable one-shot delay (not fixed taps); requires external RC timing. | Delivers variable delay on demand but lacks simultaneous multi-output capability and edge-matching precision. | Select when adaptive delay adjustment is required and deterministic multi-tap outputs are not needed. |
Compared with DS1100LU-300+, DS1023-300+ offers fewer taps but identical packaging and supply, while 74LVC1G123DBVR trades fixed multi-output precision for configurability - making DS1100LU-300+ optimal for static, high-fidelity timing alignment where tap count and edge fidelity are non-negotiable.

FAQ
What is the maximum input frequency supported by DS1100LU-300+?
The DS1100LU-300+ does not specify a maximum input frequency but defines minimum input pulse width (tWI) as 20% of TAP 5 delay - i.e., ≥60ns - corresponding to a maximum fundamental repetition rate of ~8.3MHz. Higher frequencies may degrade delay accuracy due to layout sensitivity and decoupling effects, as noted in datasheet Note 9.
Does DS1100LU-300+ support both rising and falling edge delays with equal accuracy?
Yes, DS1100LU-300+ is explicitly designed to reproduce both leading and trailing edges with equal precision. The datasheet confirms matched tPLH and tPHL tolerances (±4ns for short delays, ±13% for longer ones), and Note 1 states initial tolerances apply to both edges at +25°C and 3.3V.
Can DS1100LU-300+ drive 74ACT logic families directly?
DS1100LU-300+ specifies drive capability for 10 LS-TTL loads (8mA sink / -1mA source). While 74ACT inputs draw less current, their higher input capacitance (~10pF) may affect edge fidelity. The device's 2.0–2.5ns rise/fall times remain compatible, but layout decoupling and trace length should be optimized per application.
Is DS1100LU-300+ pin-compatible with other DS1100L variants in µMAX packages?
Yes, all DS1100LU-xxx variants share identical 8-pin µMAX pinout (IN, TAP 2, TAP 4, GND, TAP 5, TAP 3, TAP 1, VCC), enabling drop-in replacement across delay values without PCB changes - confirmed by Maxim's ordering table and pin assignment diagram.
What is the power-up time specification for DS1100LU-300+?
The DS1100LU-300+ has a specified power-up time (tPU) of 200μs, defined as the time from VCC reaching 3.0V until outputs become valid. This ensures deterministic initialization in systems with sequenced power rails or brown-out recovery circuits.
