Product details
Overview
DS1135Z-15 from Maxim Integrated is a high-speed, all-silicon 3-channel digital delay line operating at +5V with precise 15 ns per-output delay (tPLH/tPHL), ±1.5 ns tolerance over -40°C to +85°C, and leading/trailing edge symmetry preservation. It drives up to 10 LS loads and is used in clock skew correction, pulse width adjustment, and timing alignment in industrial control and test instrumentation.
For engineers reviewing the DS1135Z-15 datasheet, DS1135Z-15 pinout, DS1135Z-15 application, or DS1135Z-15 equivalent, key selection factors include guaranteed 15 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 higher speed and silicon reliability.
Technical Context
The DS1135Z-15 implements three independent buffered delay paths within a single monolithic silicon IC, each delivering identical 15 ns propagation delay for both rising (tPLH) and falling (tPHL) edges. Its logic-buffered outputs maintain input waveform symmetry and support TTL/LS-level interfacing.
It operates strictly at +5V (4.75–5.25 V), with no 3V capability-DS1135L variants are required for lower-voltage systems. Power-up stabilization completes within 100 ms, 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 | 15 ns (tPLH/tPHL), matched across all three channels for synchronized timing alignment |
| Delay tolerance | ±1.5 ns over -40°C to +85°C and 4.75–5.25 V supply, enabling stable operation in industrial environments |
| Supply voltage | +5V only (4.75–5.25 V); not compatible with 3V systems-requires DS1135L for 3V operation |
| Output drive strength | Drives ≥10 LS-TTL loads per channel, supporting fanout without external buffering |
| Rise/fall time | 2.0–2.5 ns (measured at 1.5 V, 15 pF load), ensuring fast edge integrity in high-speed digital timing |
| Operating temperature | -40°C to +85°C industrial grade, validated per Absolute Maximum Ratings and AC specs |
| Input capacitance | 10 pF typical, minimizing loading on upstream signal sources |
Pinout & Package
DS1135Z-15 is housed in an 8-pin SOIC package (150-mil width, outline 21-0041), RoHS-compliant (suffix "+"), with gull-wing leads suitable for vapor phase, IR, and wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2, IN3 | Digital input signals | Three independent TTL/LS-compatible inputs; each routed to its dedicated 15 ns delay path |
| OUT1, OUT2, OUT3 | Delayed digital outputs | Buffered, edge-symmetric outputs with 15 ns fixed delay; each drives ≥10 LS loads |
| VCC | Positive supply | +5V power pin (4.75–5.25 V); decoupling required near pin for noise-sensitive timing |
| GND | Ground reference | Common return for all inputs, outputs, and internal circuitry; must be low-impedance |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates aging, drift, and mechanical failure modes of analog or SAW-based delay lines |
| Leading & trailing edge precision | Maintains input duty cycle symmetry-critical for clock distribution and pulse shaping |
| Three independent buffered delays | Enables parallel timing adjustments without cross-talk or shared path delay variation |
| Industrial temperature range support | Validated performance from -40°C to +85°C ensures reliability in harsh embedded environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1135Z-12+ | 12 ns fixed delay per output; ±1.0 ns initial tolerance, ±1.5 ns over temp/voltage | Suitable where shorter delay is acceptable and tighter initial accuracy is prioritized | Select DS1135Z-12+ when system timing budget allows 3 ns reduction and initial calibration stability is critical |
| DS1135Z-20+ | 20 ns fixed delay per output; ±1.5 ns initial tolerance, ±2 ns over temp/voltage | Used where longer propagation margin is needed for signal integrity or margin analysis | Choose DS1135Z-20+ when design requires additional timing slack for worst-case trace skew or voltage droop |
Compared with DS1135Z-12+ and DS1135Z-20+, the DS1135Z-15 offers the optimal balance of delay duration, temperature/voltage stability (±1.5 ns), and industrial-grade robustness-making it the preferred choice for mid-range timing alignment where 15 ns precisely meets system skew budgets.

FAQ
What is the exact delay value and tolerance specification for DS1135Z-15?
The DS1135Z-15 provides a nominal 15 ns delay for each of its three outputs (tPLH and tPHL). Initial tolerance is ±1.0 ns at +25°C and 5.0 V; over the full industrial temperature range (-40°C to +85°C) and supply voltage (4.75–5.25 V), delay tolerance is ±1.5 ns. This is explicitly defined in Table 1 of the official DS1135 datasheet Rev 8/12.
Can DS1135Z-15 operate from a 3.3V supply?
No, DS1135Z-15 is specified exclusively for +5V operation (4.75–5.25 V). Attempting 3.3V operation will result in undefined timing behavior and potential functional failure. For 3V systems, the DS1135L family (e.g., DS1135L-15) is the designated alternative, as noted in the datasheet's "5V Operation (Refer to DS1135L for 3V Operation)" statement.
Is DS1135Z-15 pin-compatible with DS1013 or DS1035?
Yes-DS1135Z-15 is explicitly recommended as a replacement for DS1013 and DS1035 in the datasheet's FEATURES section. It uses the same 8-pin SOIC (150-mil) footprint and identical pin assignment (IN1–IN3, OUT1–OUT3, VCC, GND), enabling drop-in replacement without PCB layout changes.
What load can each output of DS1135Z-15 drive?
Each output of DS1135Z-15 is rated to drive up to 10 LS-TTL loads, as stated in the DESCRIPTION section. This corresponds to a DC output current capability of ±12 mA (low-level) and –1.0 mA (high-level) under specified conditions, verified in the DC Electrical Characteristics table.
Does DS1135Z-15 support both rising and falling edge delay accuracy?
Yes, DS1135Z-15 guarantees identical 15 ns delay for both rising edges (tPLH) and falling edges (tPHL), preserving input signal symmetry. The datasheet emphasizes "Leading and Trailing Edge Precision" as a core feature and confirms this in Table 1 and the AC Electrical Characteristics section.
