Product details
Overview
DS1135Z-30+ from Maxim Integrated is a high-speed, all-silicon 3-channel digital delay line operating at +5V with precise 30ns per-output delay (tPLH/tPHL), ±1.5ns initial tolerance, and ±2ns tolerance over -40°C to +85°C. It preserves input signal symmetry with leading/trailing edge accuracy and drives up to 10 LS TTL loads. Used in clock skew management and timing alignment in industrial control logic.
For engineers reviewing the DS1135Z-30+ datasheet, DS1135Z-30+ pinout, DS1135Z-30+ application, or DS1135Z-30+ equivalent, key selection factors include guaranteed 30ns delay stability across voltage (4.75–5.25V) and temperature, SOIC-8 package compatibility, and direct replacement suitability for legacy DS1013/DS1035 designs requiring higher speed and tighter tolerance.
Technical Context
The DS1135Z-30+ implements three independent buffered delay paths within a single silicon die, each delivering identical 30ns propagation delay for both rising (tPLH) and falling (tPHL) edges. Its all-silicon architecture eliminates quartz aging and thermal hysteresis issues inherent in analog or crystal-based solutions.
Designed for deterministic timing alignment, it maintains input pulse symmetry with matched rise/fall delay accuracy and supports 100% tap delay input pulse width (tWI ≥ 30ns). Power-up time is 100ms, and output rise/fall times are specified at 2.0–2.5ns into 15pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per output | 30ns (tPLH/tPHL), identical across all three channels |
| Initial delay tolerance | ±1.5ns at +25°C, VCC = 5.0V - sets baseline timing margin for PCB-level timing budgeting |
| Tolerance over temp/voltage | ±2ns from -40°C to +85°C and 4.75–5.25V - ensures stable skew control in industrial environments |
| Output drive strength | Drives ≥10 LS-TTL loads - enables fanout without external buffers in logic timing chains |
| Rise/fall time | 2.0–2.5ns (20%/80% points, 15pF load) - supports clean edge integrity at >100MHz effective toggle rates |
| Supply voltage | +5V ±5% (4.75–5.25V) - compatible with standard 5V logic rails and decoupling practices |
Pinout & Package
DS1135Z-30+ 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, notch-marked side).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN3 | Independent digital input signals | Three asynchronous inputs, each routed to its dedicated delay path; no internal crosstalk coupling |
| OUT1–OUT3 | Buffered delayed outputs | Each output delivers identical 30ns delay with LS-TTL-compatible voltage levels and drive capability |
| VCC | Positive supply | +5V power rail; requires local 0.1µF ceramic decoupling adjacent to pin |
| GND | Ground reference | Common return for all inputs, outputs, and internal circuitry; must be low-impedance plane |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates quartz aging, shock sensitivity, and thermal hysteresis - ideal for long-life industrial deployments |
| Leading and trailing edge precision | Matched tPLH/tPHL ensures preserved duty cycle and minimal jitter accumulation in feedback or cascaded paths |
| Three independent buffered delays | Enables parallel timing alignment of multiple signals (e.g., clock/data strobes) without inter-channel skew |
| 5V operation with LS-TTL compatibility | Direct interface with 74LS/74F logic families; no level-shifting required in legacy 5V systems |
Applications
| Industrial PLC Timing Alignment | Digital Test Equipment Signal Staging |
|---|---|
Use Scenario: Synchronizing I/O scan cycles and interrupt response windows across distributed modules in programmable logic controllers. IC Role / Device Role / Timing Role: Provides deterministic, temperature-stable delay for aligning enable strobes and status sampling clocks. Use Value: Eliminates timing violations caused by trace-length mismatches; maintains <±2ns channel-to-channel skew over full industrial temperature range. | Use Scenario: Generating precisely offset trigger and capture windows in automated test equipment (ATE) pattern generators. IC Role / Device Role / Timing Role: Delays reference clocks or stimulus signals to create controlled setup/hold intervals for DUT interface validation. Use Value: Enables sub-nanosecond relative timing resolution without FPGA-based delay tuning or calibration overhead. |
| Legacy System DS1013/DS1035 Replacement | High-Speed Logic Skew Compensation |
Use Scenario: Upgrading aging instrumentation or telecom line cards originally designed with DS1013 or DS1035 delay lines. IC Role / Device Role / Timing Role: Drop-in functional replacement offering faster speed (30ns vs. older variants), tighter tolerance, and improved reliability. Use Value: No PCB redesign needed; same SOIC-8 footprint and pinout preserves BOM continuity while improving timing margin. | Use Scenario: Compensating for propagation delay mismatches between parallel data bus lines and associated clock/strobe signals. IC Role / Device Role / Timing Role: Introduces calibrated delay on clock or control lines to realign timing margins at receiver inputs. Use Value: Restores setup/hold compliance in high-speed parallel interfaces (e.g., memory address latching, bus arbitration) without altering layout. |
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-25+ | 25ns fixed delay per output; ±1.5ns initial tolerance; otherwise identical AC/DC specs and pinout | Suitable where 5ns shorter delay meets system timing budget; not interchangeable if 30ns is required for hold-time compliance | Select only if design allows reduction in absolute delay; verify timing closure with 5ns delta |
| DS1135Z-35+ | 35ns fixed delay per output; ±1.5ns initial tolerance; same package, voltage, and temperature specs | Used when longer delay is needed to meet minimum pulse width or setup margin requirements | Choose when 30ns is insufficient; confirm downstream logic can tolerate increased latency |
Compared with DS1135Z-25+ and DS1135Z-35+, the DS1135Z-30+ provides the exact 30ns delay required for applications where intermediate timing alignment is critical-neither under- nor over-compensating skew, and maintaining optimal margin against jitter-induced timing violations.

FAQ
What is the guaranteed delay accuracy of DS1135Z-30+ over its full operating temperature range?
The DS1135Z-30+ guarantees ±2ns delay tolerance over -40°C to +85°C and 4.75–5.25V supply. This includes both tPLH and tPHL measurements referenced to the 1.5V logic threshold, ensuring symmetric leading/trailing edge alignment remains within specification across environmental stress.
Is DS1135Z-30+ pin-compatible with DS1013 or DS1035?
Yes - DS1135Z-30+ uses the same 8-pin SOIC (150-mil) package and identical pin assignment (IN1–IN3, OUT1–OUT3, VCC, GND) as DS1013 and DS1035. It is explicitly recommended as a drop-in replacement, requiring no PCB changes or layout modifications.
Can DS1135Z-30+ operate from a 3.3V supply?
No - DS1135Z-30+ is specified only for +5V operation (4.75–5.25V). For 3V systems, Maxim recommends the DS1135L family. Attempting 3.3V operation will result in undefined timing behavior and potential failure to meet delay or drive specifications.
What is the maximum input frequency supported by DS1135Z-30+?
DS1135Z-30+ supports input pulse periods down to 2×tWI (i.e., ≥60ns period for 30ns delay), corresponding to a maximum fundamental frequency of ~16.7MHz. Input pulse width must be ≥30ns (100% of tap delay) to ensure accurate delay reproduction.
Does DS1135Z-30+ require external termination or impedance matching?
No external termination is required. DS1135Z-30+ outputs are designed to drive standard LS-TTL loads (15pF, 10-unit loads). For high-speed routing (>50MHz edge rates), maintain controlled-impedance traces and minimize stub length, but series or parallel termination is not specified in the datasheet.
