Product details
Overview
DS1135LZ-12/T&R from Maxim Integrated is a 3V, 8-pin SO all-silicon delay line delivering three independent buffered delays of precisely 12 ns each (tPLH/tPHL), with ±1.0 ns initial tolerance and ±3.0 ns tolerance over -40°C to +85°C. It preserves input signal symmetry via leading/trailing edge precision and supports high-speed digital timing in clock distribution, data synchronization, and logic alignment circuits.
For engineers reviewing the DS1135LZ-12/T&R datasheet, DS1135LZ-12/T&R pinout, DS1135LZ-12/T&R application, or DS1135LZ-12/T&R equivalent, key selection criteria include guaranteed 12 ns delay matching across all three outputs, 2.7–3.6 V supply operation, sub-3 ns output rise/fall times, industrial temperature support, and SO-8 (150-mil) package compatibility with vapor-phase and IR reflow.
Technical Context
The DS1135LZ-12/T&R implements three identical, fully buffered delay paths in a single monolithic silicon circuit-no external components required. Each path delivers matched tPLH and tPHL delays of 12 ns under nominal conditions (VCC = 3.3 V, TA = +25°C), with symmetrical edge fidelity preserving input duty cycle.
It operates across 2.7–3.6 V and -40°C to +85°C, with AC characteristics specified including 2.0–2.5 ns output rise/fall times (tOR/tOF), 1 ms power-up time (tPU), and 100% pulse-width support relative to delay value. Input-to-output delay is measured at 1.5 V crossing points on both edges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per output | 12 ns (tPLH/tPHL), matched across all three outputs for synchronous signal alignment |
| Initial delay tolerance | ±1.0 ns at +25°C, 3.3 V - enables precise timing budgeting in early design stages |
| Delay tolerance (–40°C to +85°C) | ±3.0 ns - ensures stable skew control in industrial environments without recalibration |
| Supply voltage range | 2.7 V to 3.6 V - compatible with modern 3 V logic families and low-power systems |
| Output rise/fall time | 2.0–2.5 ns - maintains signal integrity for >200 MHz digital waveforms |
| Power-up time | 1 ms - defines minimum reset-to-valid-output latency after supply stabilization |
| Input capacitance | 10 pF - minimizes loading on preceding driver stage, reducing signal distortion |
Pinout & Package
DS1135LZ-12/T&R is housed in an 8-pin SOIC (150-mil body width), RoHS-compliant, tape-and-reel packaged device. The package footprint conforms to outline 21-0041 and land pattern 90-0096.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2, IN3 | Dedicated input signals for each delay channel | Accepts TTL/CMOS-compatible logic inputs; independent routing enables multi-path timing control |
| OUT1, OUT2, OUT3 | Buffered delayed outputs | Each provides identical 12 ns delay with rail-to-rail swing and low output impedance |
| VCC | +3V supply pin | Single-supply operation; requires local 0.1 µF decoupling to minimize supply-induced jitter |
| 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 associated with analog RC or crystal-based delay solutions |
| Leading and trailing edge precision | Maintains input duty cycle symmetry at output-critical for clock doubling, phase-aligned sampling, and DDR timing |
| Three independent buffered delays | Enables simultaneous delay of multiple signals without crosstalk or shared loading effects |
| Vapor-phase and IR reflow compatible | Supports standard SMT assembly processes without thermal derating or special profile requirements |
| Industrial temperature range support | Validated operation from –40°C to +85°C ensures reliability in automotive, industrial control, and outdoor equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1035Z-12+ | Higher active current (15 mA vs. 10 mA), wider delay tolerance (±5.0 ns over –40°C to +85°C), same SO-8 package | Less suitable for battery-powered or thermally constrained designs requiring tight skew control | Choose DS1135LZ-12/T&R when lower power and tighter delay stability are prioritized |
| MAX9622ETA+ | Single-channel, adjustable delay (0–100 ns), higher resolution (10 ps step), but no triple-output capability | Requires three separate devices to replicate DS1135LZ-12/T&R's 3-in-1 function-increases board area and cost | Choose DS1135LZ-12/T&R for space-constrained, fixed-delay, multi-output use cases |
Compared with DS1035Z-12+ and MAX9622ETA+, the DS1135LZ-12/T&R uniquely combines triple matched 12 ns delays, ±3.0 ns industrial-grade stability, and 10 mA active current in a single SO-8 package-making it optimal for compact, low-skew, multi-signal timing alignment.

Manufacturer
Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and timing ICs for industrial, communications, and computing applications-with emphasis on reliability, integration, and performance under real-world conditions.
The DS1135L series was developed as a low-power, high-speed silicon replacement for legacy bipolar delay lines like the DS1033, targeting applications needing deterministic, temperature-stable, multi-output delays without external tuning.
FAQ
What is the guaranteed delay accuracy of DS1135LZ-12/T&R over its full operating temperature range?
The DS1135LZ-12/T&R guarantees ±3.0 ns delay tolerance (tPLH/tPHL) across the industrial temperature range of –40°C to +85°C, measured at VCC = 2.7 V to 3.6 V. This specification ensures predictable, matched 12 ns delays for all three outputs under worst-case thermal and supply conditions-critical for skew-sensitive timing architectures.
Does DS1135LZ-12/T&R require external passive components for basic operation?
No, DS1135LZ-12/T&R is a fully self-contained all-silicon delay line requiring only a single 3 V supply and ground. No external resistors, capacitors, or crystals are needed. A 0.1 µF ceramic decoupling capacitor placed near the VCC pin is recommended to suppress supply noise and maintain delay stability.
Can DS1135LZ-12/T&R be used with 2.5 V logic systems?
No-DS1135LZ-12/T&R is specified only for 2.7 V to 3.6 V operation. At 2.5 V, it falls outside the guaranteed DC and AC electrical specifications, risking increased delay variation, degraded output drive strength, and potential functional failure. For 2.5 V systems, consider alternative delay solutions explicitly rated for that voltage.
How does DS1135LZ-12/T&R preserve input signal symmetry between rising and falling edges?
The DS1135LZ-12/T&R achieves leading and trailing edge precision through matched internal delay paths and symmetric output buffer design. Both tPLH and tPHL are specified identically (12/12 ns) with equal tolerances, ensuring minimal duty cycle distortion-even for non-50% duty cycle inputs-enabling accurate timing in DDR, clock recovery, and pulse-width sensitive applications.
Is DS1135LZ-12/T&R pin-compatible with DS1033-series delay lines?
No-DS1135LZ-12/T&R uses an 8-pin SO package with dedicated IN1–IN3 and OUT1–OUT3 pins, while DS1033 variants typically use 14-pin DIP or SO packages with different pinouts and dual-output configurations. Although DS1135LZ-12/T&R is positioned as a functional replacement, physical redesign is required to migrate from DS1033 to DS1135LZ-12/T&R.
