Product details
Overview
DS1100LU-30+ from Maxim Integrated is a 3.3V, 8-pin µMAX-packaged silicon delay line with five equally spaced taps delivering nominal delays of 6ns, 12ns, 18ns, 24ns, and 30ns. It reproduces both leading and trailing edges with ±4ns tolerance over –40°C to +85°C, drives up to 10 LS-TTL loads per tap, and operates across 3.0V–3.6V supply. It is used in high-speed timing alignment for logic synchronization and pulse shaping in industrial control interfaces.
For engineers reviewing the DS1100LU-30+ datasheet, DS1100LU-30+ pinout, DS1100LU-30+ application, or DS1100LU-30+ equivalent, key selection criteria include tap delay precision across temperature, edge fidelity for dual-edge timing, TTL/CMOS compatibility, low-power CMOS operation, and µMAX footprint constraints in space-constrained PCB layouts.
Technical Context
The DS1100LU-30+ implements an all-silicon delay architecture-no hybrid or ceramic components-ensuring stable propagation delay without aging or thermal hysteresis. Each of its five taps provides fixed, monotonic delay increments derived from a single monolithic delay chain, guaranteeing correlated drift under voltage or temperature variation.
It supports full-rail input logic (VIH ≥ 2.0V, VIL ≤ 0.8V) and delivers rail-to-rail output swing referenced to 3.3V, with tPLH/tPHL measured at 1.5V crossing points. Rise/fall times are ≤2.5ns, and power-up time is ≤200μs, enabling use in systems requiring deterministic startup behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures compatibility with 3.3V logic domains and robust noise margin |
| Nominal Tap Delays | 6ns / 12ns / 18ns / 24ns / 30ns - fixed, equally spaced delays for precise multi-point timing alignment |
| Delay Tolerance | ±4ns (≤40ns taps, –40°C to +85°C) - enables deterministic setup/hold margin calculation in synchronous logic |

| 3 | TAP 4 | Fourth delay output (24ns); shares same output structure and load capability as TAP 2 |
| 4 | GND | Analog/digital ground reference; must be connected to low-impedance system ground plane |
| 5 | TAP 5 | Fifth delay output (30ns); highest-delay tap, specified with same accuracy and drive strength |
| 6 | TAP 3 | Third delay output (18ns); center tap, exhibits correlated delay shift with all other taps under temp/voltage change |
| 7 | TAP 1 | First delay output (6ns); lowest-delay tap, initial point for cascaded timing chains |
| 8 | VCC | +3.3V supply; requires local 0.1μF ceramic decoupling adjacent to pin |

Equivalent & Alternatives
The following parts are listed as comparable options for similar silicon delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1023-30+ (Maxim) | 3-tap, 30ns max delay, SO-8 package, ±5% delay tolerance (not ns-absolute) | Limited to coarse delay steps; unsuitable for fine-grained multi-tap alignment | Select when only three delay points are needed and absolute ns tolerance is not required |
| MC100EP195DG (ON Semiconductor) | 5-tap ECL delay line, –3.3V supply, 100Ω differential outputs, ±1.5ps jitter | Requires level translation and biasing for 3.3V CMOS systems; higher power and complexity | Select only for ultra-low-jitter ECL environments with existing negative supply infrastructure |
Compared with DS1100LU-30+, DS1023-30+ offers fewer taps and looser tolerance but lower cost for basic delay needs, while MC100EP195DG delivers superior jitter performance at the expense of supply compatibility and design overhead.

FAQ
What is the operating temperature range for DS1100LU-30+?
The DS1100LU-30+ is fully specified and guaranteed over –40°C to +85°C. All electrical parameters-including tap delay tolerance (±4ns), supply current (10mA typical), and output drive-are validated across this industrial temperature range. The device uses silicon delay elements that exhibit monotonic, correlated drift across temperature, enabling predictable timing margin analysis in thermal cycling environments.
Does DS1100LU-30+ support both rising and falling edge delays with equal accuracy?
Yes, DS1100LU-30+ is explicitly designed to reproduce both leading and trailing edges with equal precision. Its datasheet specifies matched tPLH and tPHL tolerances (±4ns for taps ≤40ns), and internal characterization confirms symmetrical propagation through the monolithic delay chain. This ensures preserved pulse width and duty cycle integrity in applications like clock/data deskew and strobe generation.
What is the maximum capacitive load DS1100LU-30+ can drive per tap?
Each tap of DS1100LU-30+ is rated to drive up to 10 LS-TTL loads, equivalent to ~100pF total load capacitance under standard test conditions. Driving heavier loads increases rise/fall times and may degrade delay accuracy beyond ±4ns. For loads exceeding 10× 74LS, external buffer amplification is recommended to maintain timing fidelity and signal integrity.
Is DS1100LU-30+ pin-compatible with other DS1100L variants in µMAX packages?
Yes, all DS1100LU-xxx variants-including DS1100LU-30+-share identical 8-pin µMAX pinout, package outline (U8+1), and land pattern (90-0092). Delay values differ only in internal trimming; no PCB redesign is required when substituting between DS1100LU-25+, DS1100LU-30+, or DS1100LU-35+ for prototyping or production flexibility.
How does DS1100LU-30+ achieve delay stability over supply voltage variation?
DS1100LU-30+ achieves delay stability over 3.0V–3.6V via process-matched silicon delay elements with built-in voltage compensation. Its datasheet specifies delay tolerance relative to nominal value across the full supply range, and measurements confirm unidirectional delay shift-e.g., all taps slow down together as VCC decreases-enabling consistent timing margin allocation without per-tap recalibration.
