Product details
Overview
DS1100LU-60 from Maxim Integrated is a 3.3V, 5-tap silicon delay line delivering precisely spaced delays of 12ns, 24ns, 36ns, 48ns, and 60ns across its output taps. It operates over -40°C to +85°C, supports TTL/CMOS-compatible logic levels, and drives up to 10 74LS loads per tap. Used in high-speed timing alignment, clock deskewing, and pulse-width adjustment circuits.
For engineers reviewing the DS1100LU-60 datasheet, DS1100LU-60 pinout, DS1100LU-60 application, or DS1100LU-60 equivalent, key selection criteria include tap delay accuracy (±4ns over full temperature range), low-power CMOS operation (10mA typical ICC), µMAX-8 package compatibility, and leading/trailing-edge fidelity for edge-sensitive signal conditioning.
Technical Context
The DS1100LU-60 implements an all-silicon delay architecture with fixed, monotonic delay progression across five equally spaced taps-no PLL, oscillator, or programmable logic involved. Delay values are factory-trimmed and stable over voltage (3.0V–3.6V) and temperature (-40°C to +85°C), with unidirectional drift behavior ensuring relative tap spacing remains consistent.
Each tap reproduces both rising and falling edges with equal precision at the 1.5V threshold, supporting accurate pulse shaping in digital timing paths. Input-to-output propagation is measured at 1.5V crossing points, and output rise/fall times are specified at 2.0–2.5ns, enabling use in sub-5ns timing-critical applications without external buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures compatibility with 3.3V logic systems and robust noise margin |
| Nominal Tap Delays | 12ns / 24ns / 36ns / 48ns / 60ns - fixed, equally spaced delays for deterministic signal alignment |
| Delay Tolerance | ±4ns (≤40ns taps) or ±13% (>40ns taps) over -40°C to +85°C - enables reliable timing margining in industrial environments |
| Output Drive Strength | 8mA sink / -1mA source - sufficient to directly drive 10× 74LS loads without external buffers |
| Input Pulse Width | ≥20% of Tap 5 delay (≥12ns) - defines minimum usable input pulse duration for valid tap output generation |
| Power-Up Time | 200μs - establishes maximum delay before stable operation after VCC application |
| Rise/Fall Time | 2.0ns to 2.5ns - supports clean edge transitions in high-speed digital timing chains |
Pinout & Package
DS1100LU-60 is housed in an 8-pin µMAX package (U8+1 outline, 3mm × 3mm footprint), compatible with vapor-phase and IR reflow soldering. The package is RoHS-compliant and lead(Pb)-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 3 TAP 4 | Fourth Delay Output | Delivers input signal delayed by 48ns; same electrical specs as other taps |
| 4 GND | Ground Reference | Primary return path for supply and signal currents; must be low-impedance |
| 5 TAP 5 | Fifth Delay Output | Delivers input signal delayed by 60ns; highest-delay tap in the series |
| 6 TAP 3 | Third Delay Output | Delivers input signal delayed by 36ns; maintains monotonic delay relationship with adjacent taps |
| 7 TAP 1 | First Delay Output | Delivers input signal delayed by 12ns; lowest-delay tap, used for fine-grained timing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-60 | Same delay values and electrical specs, but in 8-pin SO (150-mil) package instead of µMAX | Preferred for through-hole prototyping or boards with legacy SO footprints; larger PCB area required | Select when SO package compatibility or manual assembly is prioritized over space-constrained layouts |
| MAX9602EUA+ | Single-output, adjustable delay (0–100ns) via external resistor; not multi-tap; higher power consumption (25mA) | Suitable for variable-delay applications but lacks simultaneous multi-tap outputs and fixed delay precision | Choose only when programmability outweighs need for deterministic, multi-point delay distribution |
Compared with DS1100LZ-60 and MAX9602EUA+, the DS1100LU-60 uniquely delivers five fixed, equally spaced delays in the smallest industry-standard surface-mount package-enabling compact, repeatable timing solutions where tap count, delay granularity, and board space are jointly constrained.

FAQ
What is the operating voltage range for DS1100LU-60?
The DS1100LU-60 operates from 3.0V to 3.6V, with typical performance characterized at 3.3V. This range ensures compatibility with standard 3.3V logic families while maintaining stable delay accuracy across supply variations. Operation outside this range may compromise timing specifications or reliability. The DS1100LU-60 is not rated for 5V operation.
Does DS1100LU-60 support both rising and falling edge delays?
Yes, the DS1100LU-60 reproduces both leading and trailing edges with equal precision-tPLH and tPHL delays are matched and specified identically across all taps. This capability is essential for preserving pulse width integrity in digital signal conditioning. The DS1100LU-60 achieves this via symmetric internal delay elements, not post-processing or separate paths.
What is the maximum capacitive load the DS1100LU-60 can drive per tap?
The DS1100LU-60 is specified to drive up to 10 standard 74LS logic inputs per tap, corresponding to approximately 100pF total load capacitance under typical conditions. Exceeding this load increases propagation delay variation and may degrade output rise/fall times. For heavier loads, buffer amplification is recommended. The DS1100LU-60 does not include on-die termination or slew-rate control.
Is DS1100LU-60 pin-compatible with other DS1100L variants?
Yes, all DS1100L variants-including DS1100LU-60 and DS1100LZ-60-share identical 8-pin assignments and electrical behavior; only the package differs (µMAX vs. SO). No PCB redesign is needed when migrating between them, provided land patterns match the respective package outlines. The DS1100LU-60 uses U8+1 footprint, while DS1100LZ-60 uses S8+4.
How does temperature affect delay accuracy in DS1100LU-60?
Over -40°C to +85°C, DS1100LU-60 delay tolerance is ±4ns for taps ≤40ns (TAP 1–TAP 4) and ±13% for TAP 5 (60ns). All taps drift unidirectionally with temperature-e.g., if TAP 1 slows, all others slow proportionally-preserving relative spacing. This behavior is documented in Note 3 of the datasheet and confirmed in DS1100LU-60 characterization data.
