Product details
Overview
DS1100LU-100/T&R from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 20ns, 40ns, 60ns, 80ns, and 100ns across TAP1–TAP5. It operates from 3.0V to 3.6V over –40°C to +85°C, reproduces both leading and trailing edges with ±4ns tolerance (–40°C to +85°C), and drives up to 10 × 74LS loads per tap. Used in high-speed timing alignment for test equipment and digital signal synchronization.
For engineers reviewing the DS1100LU-100/T&R datasheet, DS1100LU-100/T&R pinout, DS1100LU-100/T&R application, or DS1100LU-100/T&R equivalent, key selection criteria include tap delay precision across temperature, TTL/CMOS compatibility, µMAX® package footprint, and edge-fidelity performance in clock/data alignment circuits.
Technical Context
The DS1100LU-100/T&R implements an all-silicon delay architecture with five fixed, equally spaced output taps - no PLL, oscillator, or programmable logic. Delay values are factory-trimmed and stable across voltage (3.0V–3.6V) and temperature (–40°C to +85°C), with unidirectional drift behavior: all taps slow or speed together under varying conditions.
Each tap delivers CMOS-compatible output levels (VOH ≥ 2.3V, VOL ≤ 0.5V at VCC = 3.0V) with 2.0–2.5ns rise/fall times and supports input pulse widths down to 20% of Tap 5 delay. Power-up time is 200μs, and active supply current is 10mA at 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures compatibility with 3.3V logic systems without level-shifting. |
| Nominal Delays (TAP1–TAP5) | 20ns / 40ns / 60ns / 80ns / 100ns - enables precise multi-point timing skew correction in parallel data paths. |
| Delay Tolerance (–40°C to +85°C) | ±4ns for ≤40ns taps; ±13% for >40ns taps - guarantees deterministic timing margin in industrial environments. |
| Output Drive Strength | 8mA sink / –1mA source - sufficient to directly drive 10 × 74LS inputs without buffering. |
| Rise/Fall Time | 2.0ns to 2.5ns - preserves signal integrity for sub-5ns edge alignment applications. |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded timing control and ATE systems. |
Pinout & Package
DS1100LU-100/T&R is housed in an 8-pin µMAX® package (U8+1 outline, 3mm × 3mm, 0.65mm pitch), compatible with vapor-phase and IR reflow soldering. Pin 1 is IN; pins 2–5 are TAP2–TAP5; pin 6 is TAP3; pin 7 is TAP1; pin 8 is VCC; pin 4 is GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Input signal terminal | Accepts TTL/CMOS-compatible logic transitions; defines start point for all tap delays. |
| TAP 2 (Pin 2) | Second delayed output | Delivers input signal after 40ns nominal delay; edge-aligned with TAP1–TAP5 for synchronous sampling. |
| TAP 4 (Pin 3) | Fourth delayed output | Provides 80ns delay; used for intermediate timing points in multi-stage pipeline alignment. |
| GND (Pin 4) | Ground reference | Common return path for all I/O and supply currents; requires low-inductance PCB connection. |
| TAP 5 (Pin 5) | Fifth delayed output | Final tap at 100ns; highest delay in series; critical for end-of-chain timing calibration. |
| TAP 3 (Pin 6) | Third delayed output | 60ns delay node; central tap enabling symmetric delay interpolation in signal deskew networks. |
| TAP 1 (Pin 7) | First delayed output | 20ns delay; shortest tap for fine-grained timing adjustment near signal source. |
| VCC (Pin 8) | Power supply | +3.3V supply input; must be decoupled locally with 0.1μF ceramic capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates hybrid or ceramic delay line reliability risks; enables full CMOS process compatibility and wafer-level testability. |
| Equal tap spacing | Fixed 20ns increments between consecutive taps - simplifies linear delay interpolation and reduces calibration complexity. |
| Leading- and trailing-edge fidelity | ±4ns matching between tPLH and tPHL across temperature - essential for duty-cycle preservation in clock distribution. |
| TTL-/CMOS-compatible I/O | VIH ≥ 2.0V, VIL ≤ 0.8V, IOH/IOH compliant - allows direct interface with legacy 74LS and modern 3.3V logic families. |
| µMAX® surface-mount package | 3mm × 3mm footprint with 0.65mm pitch - saves >60% board area vs. SO-8 while maintaining hand-solderability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-100/T&R | SO-8 package (5.0mm × 4.0mm); same electrical specs and delay values. | Requires larger PCB area; better thermal dissipation but less suitable for space-constrained modules. | Select when board layout prioritizes manufacturability over footprint size or when existing SO-8 land patterns exist. |
| ON Semiconductor MC100EP195DG | Differential ECL output; 3.3V supply; 5-tap with 25ps resolution; higher power (35mA ICC). | Designed for RF/microwave timing; not TTL/CMOS compatible; requires termination and biasing. | Select only for ultra-low-jitter differential systems where single-ended DS1100LU-100/T&R cannot meet phase-noise requirements. |
Compared with DS1100LZ-100/T&R and MC100EP195DG, DS1100LU-100/T&R uniquely balances minimal footprint, single-ended 3.3V compatibility, and industrial temperature stability - making it optimal for compact ATE modules and embedded test peripherals where board area and logic-family interoperability are primary constraints.

FAQ
What is the maximum operating frequency supported by DS1100LU-100/T&R?
The DS1100LU-100/T&R does not specify a maximum operating frequency - instead, it defines minimum input pulse width (tWI) as 20% of Tap 5 delay (i.e., 20ns for DS1100LU-100/T&R). At 1MHz, active current is 10mA; higher frequencies increase ICC. For reliable operation, input period should exceed 2×tWI, and layout must minimize noise coupling to maintain delay accuracy.
Does DS1100LU-100/T&R support both rising and falling edge delays with equal accuracy?
Yes, DS1100LU-100/T&R is explicitly designed to reproduce both leading and trailing edges with equal precision. The datasheet specifies matched tPLH and tPHL tolerances (±4ns for ≤40ns taps, ±13% for >40ns taps over –40°C to +85°C), ensuring duty cycle integrity and symmetric timing alignment in bidirectional signal paths.
Can DS1100LU-100/T&R drive standard TTL loads directly?
Yes, DS1100LU-100/T&R can drive up to 10 × 74LS loads per tap. Its output drive strength (IOL = 8mA, IOH = –1mA at VCC = 3.0V) meets 74LS input requirements (IIH ≤ 20μA, IIL ≤ –0.4mA), and its VOH/VOL levels (≥2.3V / ≤0.5V) satisfy TTL logic thresholds - no buffer stage is required for direct interfacing.
Is DS1100LU-100/T&R RoHS-compliant and lead(Pb)-free?
Yes, DS1100LU-100/T&R is RoHS-compliant and lead(Pb)-free. The "+" suffix in the full ordering code (e.g., DS1100LU-100+/T&R) denotes compliance, and the µMAX® package uses lead-free terminations. Reflow soldering is rated to +260°C for lead-free processes, per the datasheet's Absolute Maximum Ratings table.
How does temperature variation affect delay accuracy in DS1100LU-100/T&R?
Temperature variation causes unidirectional delay drift across all taps: if one tap slows, all slow proportionally. Over –40°C to +85°C, DS1100LU-100/T&R maintains ±4ns tolerance for TAP1 (20ns) and ±13% for TAP5 (100ns). This behavior is guaranteed in the AC Electrical Characteristics table and eliminates differential skew between taps under thermal stress.
