Product details
Overview
DS1135U-10 from Maxim Integrated is a high-speed, +5V silicon delay line IC providing three independent buffered logic delays of precisely 10 ns each, with ±1.0 ns initial tolerance and ±1.5 ns tolerance over -40°C to +85°C. It preserves input signal symmetry via leading/trailing edge precision, drives up to 10 LS loads per output, and is used in high-reliability timing alignment for digital test equipment and FPGA clock domain bridging.
For engineers reviewing the DS1135U-10 datasheet, DS1135U-10 pinout, DS1135U-10 application, or DS1135U-10 equivalent, key selection criteria include guaranteed 10 ns delay accuracy across temperature/voltage, SOIC-8 (150-mil) package compatibility, 5V-only operation, and direct replacement suitability for legacy DS1013/DS1035 designs requiring improved edge fidelity and stability.
Technical Context
The DS1135U-10 implements an all-silicon delay architecture-no external RC networks or crystal elements-with three fully independent delay paths sharing a single 5V supply. Each path delivers matched tPLH/tPHL = 10 ns under nominal conditions (25°C, 5.0V), with identical delay values across all outputs.
It operates across industrial temperature (-40°C to +85°C) and voltage (4.75V–5.25V) ranges, maintaining ≤±1.5 ns total delay variation. Input-to-output propagation is measured at the 1.5V threshold, and output rise/fall times are specified at 2.0–2.5 ns into 15 pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per output | 10 ns ±1.0 ns (initial), ±1.5 ns over full temp/voltage range |
| Supply voltage | +5V ±5% (4.75V–5.25V); no 3V operation supported |
| Input/output edge accuracy | Preserves input symmetry: tPLH and tPHL both 10 ns, same tolerance |

Pinout & Package
DS1135U-10 is housed in an 8-pin SOIC (150-mil) package, RoHS-compliant, vapor-phase, IR, and wave solderable. Pin 1 is IN2 (top-left corner when notch faces up).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN3 | Independent logic inputs | Accept TTL/CMOS-compatible signals; VIH ≥2.2V, VIL ≤0.8V |
| OUT1–OUT3 | Buffered delay outputs | Each provides 10 ns delayed copy of corresponding input; 15 pF load max |
| VCC | Positive supply | +5V only; decoupling required near pin for stable delay performance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar silicon delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1135Z-10+ | Same die, identical 10 ns delay specs, but Z-grade SOIC-8 with RoHS suffix; DS1135U-10 uses U-grade marking convention | No functional difference; both qualified for industrial temp range and 5V operation | Select DS1135U-10 for legacy BOM continuity; DS1135Z-10+ for new designs requiring explicit RoHS compliance documentation |
| DS1013-10 | Older-generation bipolar delay line; ±5 ns initial tolerance, ±10 ns over temperature; higher ICC (≈50 mA) | Larger delay variation limits timing-critical applications; not suitable for <1 ns margin systems | Only consider DS1013-10 if backward compatibility with pre-2000 designs is mandatory and looser delay accuracy is acceptable |
Compared with DS1135Z-10+ and DS1013-10, the DS1135U-10 delivers superior delay stability (±1.5 ns vs ±10 ns), lower power consumption (35 mA vs 50 mA), and preserved edge symmetry-making it the preferred choice for modern digital systems demanding precise, repeatable timing alignment.

FAQ
What is the exact delay value and tolerance of DS1135U-10?
The DS1135U-10 provides a nominal delay of 10 ns per output (IN1→OUT1, IN2→OUT2, IN3→OUT3), with ±1.0 ns initial tolerance at +25°C and 5.0V, and ±1.5 ns total tolerance across -40°C to +85°C and 4.75V–5.25V. Both tPLH and tPHL are matched to this specification, preserving input duty cycle.
Is DS1135U-10 compatible with 3V logic systems?
No, DS1135U-10 is strictly a +5V device and requires VCC = 4.75V–5.25V. It does not support 3V operation. For 3V-compatible delay lines, refer to the DS1135L family-DS1135U-10 has no 3V variant or dual-supply capability.
Does DS1135U-10 require external components for stable operation?
DS1135U-10 operates as a standalone delay line with no external timing components. However, proper 0.1 µF ceramic decoupling capacitance must be placed between VCC and GND near the package to ensure stable delay performance and minimize supply-induced jitter.
Can DS1135U-10 replace DS1013 or DS1035 in existing designs?
Yes, DS1135U-10 is explicitly recommended as a replacement for DS1013 and DS1035. It shares the same 8-pin SOIC-8 (150-mil) footprint, pinout, and logic interface, while offering tighter delay tolerance, lower power, and improved temperature stability-no PCB changes are needed.
What is the maximum capacitive load DS1135U-10 can drive per output?
DS1135U-10 is characterized to drive up to 10 LS-TTL loads (equivalent to ~15 pF total load capacitance). Driving heavier loads may degrade rise/fall times and delay accuracy; for >15 pF, buffer amplification is recommended before connecting to DS1135U-10 outputs.
