Product details
Overview
DS1100LU-35 from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 7ns (TAP 1), 14ns (TAP 2), 21ns (TAP 3), 28ns (TAP 4), and 35ns (TAP 5), operating across -40°C to +85°C, delivering edge-accurate timing for high-speed digital synchronization in test equipment and logic interface circuits.
For engineers reviewing the DS1100LU-35 datasheet, DS1100LU-35 pinout, DS1100LU-35 application, or DS1100LU-35 equivalent, this device serves as a precision, low-power, TTL-/CMOS-compatible fixed-delay element where tap-to-tap spacing, leading/trailing edge fidelity, and industrial temperature stability are critical selection criteria.
Technical Context
The DS1100LU-35 implements an all-silicon delay architecture with five fixed, equally spaced output taps referenced to a single input signal; each tap reproduces both rising and falling edges with ±4ns tolerance over -40°C to +85°C at 3.3V supply.
It operates as a passive timing element-no internal clock generation or feedback control-relying on propagation through doped silicon paths; output drive capability supports up to 10 LS-TTL loads per tap, with rise/fall times ≤2.5ns and power-up time <200μs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures compatibility with 3.3V logic systems and stable delay performance across rail variation |
| Nominal Tap Delays | 7/14/21/28/35ns - fixed, linearly spaced delays enabling precise multi-point signal alignment in serial data paths |
| Delay Tolerance | ±4ns (≤40ns taps) or ±13% (>40ns taps) over full temp range - guarantees predictable skew between taps under industrial conditions |
| Input/Output Compatibility | TTL- and CMOS-compatible - allows direct interfacing with 74LS, 74F, and modern 3.3V logic families without level-shifting |
| Output Drive Strength | 8mA sink / -1mA source - sufficient to drive 10 LS-TTL loads per tap while maintaining edge integrity |
| Operating Temperature | -40°C to +85°C - validated for use in industrial control, automated test, and embedded instrumentation environments |
Pinout & Package
DS1100LU-35 is housed in an 8-pin µMAX® package (U8+1 outline, 3mm × 3mm footprint), optimized for high-density PCB layouts and compatible with vapor-phase and IR reflow soldering processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Signal Input | Accepts TTL/CMOS-level pulse; triggers all five delay paths simultaneously |
| 2 TAP 2 | Delayed Output | Delivers input waveform delayed by 14ns; edge-aligned with other taps |
| 3 TAP 4 | Delayed Output | Delivers input waveform delayed by 28ns; electrically identical to TAP 2 in drive and timing spec |
| 4 GND | Ground Reference | Provides return path for all internal delay paths and output drivers |
| 5 TAP 5 | Delayed Output | Delivers input waveform delayed by 35ns; longest fixed delay in the series |
| 6 TAP 3 | Delayed Output | Delivers input waveform delayed by 21ns; center tap for symmetric delay distribution |
| 7 TAP 1 | Delayed Output | Delivers input waveform delayed by 7ns; shortest fixed delay, used for fine-grained timing adjustment |
| 8 VCC | Power Supply | +3.3V supply pin; requires local 0.1μF decoupling for stable delay accuracy |

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-35 | Same electrical specs and delay values; packaged in 8-pin SO (150-mil) instead of µMAX | Preferred for through-hole prototyping or legacy SO footprints; larger board area required | Select when SO package compatibility or hand-soldering is prioritized over space-constrained layouts |
| ON Semiconductor MC100EP195DG | 5-tap ECL delay line; requires -3.3V supply and differential inputs/outputs; ±0.35% delay accuracy vs. ±4ns absolute | Suited for RF/microwave timing or ultra-low-jitter applications; incompatible with single-ended 3.3V logic | Choose only when ECL signaling, sub-1% relative delay stability, or higher frequency operation (>1GHz) is required |
Compared with DS1100LZ-35 and MC100EP195DG, the DS1100LU-35 uniquely balances compact µMAX packaging, single-supply 3.3V operation, and guaranteed absolute delay tolerance-making it optimal for space-constrained industrial and test equipment where ease of integration and deterministic timing matter most.

FAQ
What is the nominal delay value for each tap of the DS1100LU-35?
The DS1100LU-35 provides five equally spaced nominal delays: TAP 1 = 7ns, TAP 2 = 14ns, TAP 3 = 21ns, TAP 4 = 28ns, and TAP 5 = 35ns. These values are specified at +25°C and VCC = 3.3V, with tolerances tightened to ±4ns over the full -40°C to +85°C operating range for all taps. The DS1100LU-35 achieves this via monolithic silicon delay paths, not external components or programmable logic.
Does the DS1100LU-35 support both rising and falling edge delays with equal accuracy?
Yes, the DS1100LU-35 is explicitly designed to reproduce both leading and trailing edges with equal precision-verified by tPLH (rising delay) and tPHL (falling delay) measurements at the 1.5V threshold. This edge symmetry ensures pulse width integrity across all five taps, which is essential for applications like strobe generation and clock/data deskewing. The DS1100LU-35 maintains this behavior across its full voltage (3.0V–3.6V) and temperature (-40°C to +85°C) range.
What is the maximum capacitive load the DS1100LU-35 can drive per tap?
The DS1100LU-35 is rated to drive up to 10 LS-TTL loads per tap, equivalent to approximately 20pF total load capacitance under standard test conditions. Its output stage delivers 8mA sink and -1mA source current, ensuring clean edge transitions even with moderate fanout. Exceeding this load may increase rise/fall times beyond the specified 2.5ns and degrade delay accuracy. For heavier loads, buffer amplification is recommended-DS1100LU-35 itself does not include on-chip termination or adjustable drive strength.
Is the DS1100LU-35 RoHS-compliant and lead(Pb)-free?
Yes, the DS1100LU-35 is offered in a lead(Pb)-free and RoHS-compliant package, indicated by the "+" suffix in ordering codes such as DS1100LU-35+. It supports standard lead-free reflow profiles up to +260°C and is compatible with vapor-phase and infrared soldering processes. The µMAX package (U8+1 outline) meets JEDEC J-STD-020 moisture sensitivity level 1, eliminating bake requirements prior to assembly. DS1100LU-35 conforms to Maxim Integrated's environmental compliance standards without performance trade-offs.
Can the DS1100LU-35 be used in place of the DS1100LZ-35?
The DS1100LU-35 and DS1100LZ-35 share identical electrical specifications, delay values, and timing performance-but differ only in package: µMAX (3mm × 3mm) versus SO (150-mil). They are functionally interchangeable in circuit design, though layout changes are required due to different footprints and thermal characteristics. DS1100LU-35 offers higher density and lower thermal resistance, while DS1100LZ-35 suits legacy SO-based designs. Neither is pin-compatible with the other-DS1100LU-35 is not a drop-in replacement for DS1100LZ-35 without PCB revision.
