Product details
Overview
DS1100LU-125 from Maxim Integrated is a 3.3V, 5-tap silicon delay line delivering precisely spaced delays of 25ns, 50ns, 75ns, 100ns, and 125ns across its output taps. It operates over -40°C to +85°C, supports TTL/CMOS logic levels, and drives up to 10 74LS loads per tap. Used in high-speed timing alignment, clock skew correction, and pulse-width modulation circuits.
For engineers reviewing the DS1100LU-125 datasheet, DS1100LU-125 pinout, DS1100LU-125 application, or DS1100LU-125 equivalent, key selection factors include tap delay accuracy (±4ns for ≤40ns delays, ±13% for >40ns), input-to-output edge fidelity, 3.3V supply compatibility, and µMAX-8 package footprint constraints.
Technical Context
The DS1100LU-125 implements an all-silicon delay architecture with fixed, monotonic delay progression across five equally spaced taps-no external components or configuration required. Each tap reproduces both leading and trailing edges with matched precision, enabling deterministic signal re-timing without duty-cycle distortion.
It functions as a passive, unidirectional timing element: input transitions propagate through internal delay stages, emerging at each tap after its nominal delay. Delay variation is correlated across taps-temperature or voltage shifts affect all taps uniformly, preserving inter-tap spacing integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures stable operation in modern 3.3V digital systems with ±0.3V margin |
| TAP 5 Delay | 125ns nominal - defines total propagation latency; used for coarse timing alignment or pulse stretching |
| Delay Tolerance (TAP 1–3) | ±4ns over -40°C to +85°C - guarantees sub-nanosecond jitter control for critical edge-sensitive logic |
| Delay Tolerance (TAP 4–5) | ±13% over -40°C to +85°C - maintains proportional spacing for wide-delay applications like burst synchronization |
| Output Drive | 8mA sink / -1mA source - sufficient to directly drive 10× 74LS inputs without buffering |
| Input Pulse Width | ≥20ns - sets minimum usable signal duration; compatible with >50MHz digital clock domains |
| Power-Up Time | 200μs - defines maximum delay before valid output after VCC stabilization |
Pinout & Package
DS1100LU-125 is housed in an 8-pin µMAX package (U8+1 outline, 3mm × 3mm, 0.65mm pitch), optimized for high-density PCB layouts and compatible with vapor-phase and IR reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Input Signal | Accepts TTL/CMOS-compatible logic transitions; referenced to GND, driven by 50Ω source impedance |
| 2 TAP 2 | Second Delay Output | Delivers input signal delayed by 50ns; capable of driving 10× 74LS loads |
| 3 TAP 4 | Fourth Delay Output | Delivers input signal delayed by 100ns; matches TAP 2 edge fidelity and loading capability |
| 4 GND | Ground Reference | Primary return path for supply and signal currents; must be low-impedance for timing stability |
| 5 VCC | Supply Voltage | +3.3V power rail; requires local 0.1μF ceramic decoupling adjacent to pin |
| 6 TAP 1 | First Delay Output | Delivers input signal delayed by 25ns; lowest-latency tap for fine-grained timing adjustment |
| 7 TAP 3 | Third Delay Output | Delivers input signal delayed by 75ns; central tap for symmetric delay distribution |
| 8 TAP 5 | Fifth Delay Output | Delivers input signal delayed by 125ns; maximum delay tap for pulse extension or phase offset |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-125 | Same electrical specs and delay values; packaged in 8-pin SO (150-mil) instead of µMAX | Requires larger PCB area; better suited for prototyping or manual assembly due to wider pin pitch | Select when board space permits and hand-soldering or socket-based validation is needed |
| ON Semiconductor MC100EP195MNR4G | 5-tap ECL delay line; 3.3V supply; ±10% delay tolerance; higher speed (≤1.5ns rise/fall); differential PECL outputs | Requires level-shifting for single-ended CMOS/TTL systems; consumes more power (~60mA) | Select only when ECL compatibility, sub-ns edge precision, or differential signaling is required |
Compared with DS1100LU-125, DS1100LZ-125 offers identical timing behavior in a larger SO package, while MC100EP195MNR4G delivers faster edges and tighter jitter but demands differential layout and higher power-making DS1100LU-125 optimal for cost-sensitive, single-ended 3.3V systems needing proven reliability and minimal design overhead.

FAQ
What is the nominal delay value for each tap of the DS1100LU-125?
The DS1100LU-125 provides five equally spaced delays: TAP 1 = 25ns, TAP 2 = 50ns, TAP 3 = 75ns, TAP 4 = 100ns, and TAP 5 = 125ns. These values are specified at +25°C and VCC = 3.3V, and remain proportionally stable across temperature and supply voltage variations. The DS1100LU-125 achieves this via monolithic silicon delay elements with correlated drift characteristics.
Does the DS1100LU-125 support both rising and falling edge delays with equal accuracy?
Yes, the DS1100LU-125 is explicitly designed to reproduce both leading and trailing edges with equal precision. Its internal architecture ensures matched tPLH and tPHL delays across all taps, preserving input pulse duty cycle. This capability is verified per the datasheet's AC Electrical Characteristics table and confirmed in the General Description section of the DS1100LU-125 documentation.
What is the maximum capacitive load the DS1100LU-125 can drive per tap?
The DS1100LU-125 is rated to drive up to 10 standard 74LS logic inputs per tap, corresponding to approximately 20pF load capacitance and 8mA sink current. Exceeding this load may degrade rise/fall times and delay accuracy. For heavier loads, external buffer amplification is recommended. The DS1100LU-125 datasheet specifies IOL = 8mA and IOH = -1mA under worst-case conditions.
Is the DS1100LU-125 RoHS-compliant and lead(Pb)-free?
Yes, the DS1100LU-125 is RoHS-compliant and lead(Pb)-free, indicated by the "+" suffix in its full orderable part number (e.g., DS1100LU-125+). It supports lead-free reflow soldering up to +260°C and meets JEDEC J-STD-020 moisture sensitivity level MSL-1. This compliance is documented in the Ordering Information and Package Information sections of the DS1100LU-125 datasheet.
Can the DS1100LU-125 operate outside the 3.0V to 3.6V supply range?
No-the DS1100LU-125 is characterized and guaranteed only for operation between 3.0V and 3.6V. Absolute maximum ratings allow up to +6.0V on any pin, but functional operation outside the specified supply range is not assured and may cause timing inaccuracy, increased ICC, or permanent damage. The DS1100LU-125 datasheet explicitly states VCC = 3.0V to 3.6V in all DC and AC electrical characteristics tables.
