Product details
Overview
DS1100LU-50/T&R from Maxim Integrated is a 3.3V, 5-tap silicon delay line in an 8-pin µMAX package, delivering precisely spaced delays of 10ns, 20ns, 30ns, 40ns, and 50ns across its taps. It reproduces both leading and trailing edges with equal precision, supports TTL/CMOS logic levels, and drives up to 10 74LS loads per tap - used in high-speed timing alignment, clock deskewing, and signal synchronization in industrial control and test equipment.
For engineers reviewing the DS1100LU-50/T&R datasheet, DS1100LU-50/T&R pinout, DS1100LU-50/T&R application, or DS1100LU-50/T&R equivalent, key selection criteria include guaranteed ±4ns delay tolerance over –40°C to +85°C, 3.0V–3.6V supply operation, low-power CMOS design, and µMAX footprint compatibility with automated SMT assembly.
Technical Context
The DS1100LU-50/T&R implements a monolithic all-silicon delay architecture with five fixed, equally spaced output taps - no external components or calibration required. Each tap replicates the input logic state after its nominal delay (10ns to 50ns), with edge fidelity maintained for both rising and falling transitions at the 1.5V threshold.
It operates across the full industrial temperature range (–40°C to +85°C) with delay stability specified as ±4ns for delays ≤40ns and ±13% for >40ns, referenced to nominal values at +25°C and VCC = 3.3V. Input-to-output propagation is measured between 1.5V points on input and tap waveforms under defined 50Ω source and 74F04-equivalent load conditions.
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 tolerance |
| Nominal Tap Delays | 10ns / 20ns / 30ns / 40ns / 50ns - fixed, monotonic spacing enables predictable signal phase offset |
| Delay Tolerance (≤40ns) | ±4ns over –40°C to +85°C - guarantees timing margin for critical setup/hold windows |
| Output Drive Strength | 8mA sink / –1mA source - sufficient to drive 10× 74LS loads without external buffering |
| Input Logic Compatibility | TTL- and CMOS-compatible VIH ≥ 2.0V, VIL ≤ 0.8V - interoperable with legacy and modern logic families |
| Power Consumption | 10mA typical ICC at 1MHz - enables low-static-power timing in battery-adjacent or thermally constrained designs |
Pinout & Package
DS1100LU-50/T&R is housed in an 8-pin µMAX package (outline U8+1, land pattern 90-0092), measuring 3mm × 3mm × 0.8mm with gull-wing leads. The package is RoHS-compliant, vapor-phase and IR solderable, and optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input; accepts TTL/CMOS-compatible signals with 50Ω source impedance |
| 2 | TAP 2 | Second delay output (20ns); reproduces input state with matched rise/fall edge accuracy |
| 3 | TAP 4 | Fourth delay output (40ns); electrically identical to other taps, rated for 10× 74LS loads |
| 4 | GND | Digital ground reference; must be connected to low-impedance system ground plane |
| 5 | TAP 5 | Fifth delay output (50ns); maximum delay tap, fully characterized over full temperature range |
| 6 | TAP 3 | Third delay output (30ns); delay varies unidirectionally with temperature/voltage vs. other taps |
| 7 | TAP 1 | First delay output (10ns); minimum delay tap, specified with ±4ns tolerance over full operating range |
| 8 | VCC | +3.3V supply input; requires local 0.1µF ceramic decoupling adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates hybrid or ceramic delay line reliability risks and aging drift; supports 10-year field life |
| Equal tap spacing | Enables linear interpolation between taps and simplifies multi-phase clock generation or sampling alignment |
| Leading- and trailing-edge matching | Ensures symmetrical pulse width preservation - critical for duty-cycle-sensitive applications like PWM timing |
| Low-power CMOS design | Reduces thermal load in dense timing subsystems and avoids need for heatsinking or airflow management |
| µMAX surface-mount package | Provides 3mm × 3mm footprint - saves >60% board area versus SO-8 while maintaining hand-solderability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-50/T&R | Same electrical specs and delay values, but in 8-pin SO (150-mil) package instead of µMAX | Preferred where board space allows larger footprint and legacy SO-8 tooling is in place | Select when µMAX reflow profile or layout density constraints do not apply |
| DS1000S-50 | 5V-only operation (4.5V–5.5V), same 5-tap architecture and ±5% delay tolerance over 0°C–70°C | Suitable only for 5V legacy systems; lacks industrial temperature rating and 3.3V compatibility | Choose only if existing 5V infrastructure prohibits voltage translation or level-shifting |
Compared with DS1100LZ-50/T&R and DS1000S-50, the DS1100LU-50/T&R uniquely combines 3.3V operation, industrial temperature range, and ultra-compact µMAX packaging - making it the sole option for space-constrained, wide-temperature embedded timing where 5V compatibility is unnecessary.

FAQ
What is the operating temperature range for DS1100LU-50/T&R?
The DS1100LU-50/T&R is fully specified and tested over the industrial temperature range of –40°C to +85°C. All delay tolerances, drive strength, and DC electrical parameters are guaranteed across this range when supplied with 3.0V–3.6V. This makes DS1100LU-50/T&R suitable for deployment in harsh environments such as factory floors, outdoor instrumentation, and automotive under-hood control units where ambient temperatures fluctuate widely.
Does DS1100LU-50/T&R require external decoupling capacitors?
Yes, DS1100LU-50/T&R requires a 0.1µF ceramic capacitor placed as close as possible to the VCC pin (Pin 8) and GND (Pin 4). This decoupling is essential to suppress supply noise induced by simultaneous tap switching and maintain delay stability within ±4ns. Failure to implement proper local decoupling may cause increased delay variation, especially at higher input frequencies or during rapid edge transitions.
Can DS1100LU-50/T&R drive standard TTL loads directly?
Yes, DS1100LU-50/T&R can drive up to 10 standard 74LS loads per tap without external buffers. Its output drive capability is specified as 8mA sink and –1mA source at VCC = 3.0V, which meets the input current requirements of 74LS family devices. However, for heavier loads or longer traces, series termination or buffer amplification is recommended to preserve signal integrity and edge fidelity.
How does the delay tolerance of DS1100LU-50/T&R change with temperature?
For DS1100LU-50/T&R, delay tolerance degrades predictably with temperature: ±4ns for all taps ≤40ns (TAP 1–TAP 4) and ±13% of nominal for TAP 5 (50ns) across –40°C to +85°C. All taps shift unidirectionally - e.g., if TAP 1 slows, TAP 2–TAP 5 slow proportionally - preserving relative spacing. This behavior is documented in Note 3 of the datasheet and verified via automated test at temperature extremes.
Is DS1100LU-50/T&R RoHS-compliant and lead(Pb)-free?
Yes, DS1100LU-50/T&R is RoHS-compliant and lead(Pb)-free, indicated by the "+" suffix in its full ordering code (though omitted in the base part number DS1100LU-50/T&R). It supports lead-free reflow soldering up to +260°C for 10 seconds and is qualified per JEDEC J-STD-020. The µMAX package uses matte tin plating and meets IPC/JEDEC standards for whisker resistance and intermetallic growth control.
