Product details
Overview
DS1135Z-30 from Maxim Integrated is a high-speed, all-silicon 3-channel digital delay line operating at +5V, delivering precise 30ns propagation delay per output (tPLH/tPHL) with ±1.5ns initial tolerance and ±2ns total variation over -40°C to +85°C. It preserves input signal symmetry via 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 criteria include guaranteed 30ns delay stability across voltage (4.75–5.25V) and temperature, SOIC-8 (150-mil) package compatibility, and direct replacement capability for legacy DS1013/DS1035 designs requiring higher speed and silicon reliability.
Technical Context
The DS1135Z-30 implements three independent buffered delay paths in a single monolithic silicon circuit, each with matched tPLH and tPHL characteristics. Its architecture eliminates analog drift and mechanical hysteresis inherent in older RC or SAW-based delay solutions.
It operates strictly as a fixed-delay, non-programmable logic timing element-no internal PLL, oscillator, or configuration registers. Delay accuracy is specified at the 1.5V switching threshold under 15pF load, with rise/fall times ≤2.5ns and power-up stabilization within 100ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per Output | 30ns ±1.5ns (initial), ±2ns over full temp/voltage range - ensures deterministic timing alignment across system clocks and data strobes |
| Supply Voltage | +5V ±5% (4.75–5.25V) - compatible with standard 5V TTL/CMOS logic rails without regulation overhead |
| Output Drive | 12mA sink / -1.0mA source at VOH=4V/VOL=0.5V - directly interfaces with 74F-series and LS-TTL loads |
| Rise/Fall Time | ≤2.5ns (20%–80%) - maintains signal integrity for >200MHz pulse repetition rates |
| Operating Temp | -40°C to +85°C - qualified for industrial-grade embedded timing applications |
| Input Capacitance | 10pF max - minimizes loading on upstream drivers and reduces layout sensitivity |
Pinout & Package
DS1135Z-30 is housed in an 8-pin SOIC (150-mil) package, RoHS-compliant, vapor-phase, IR, and wave solderable. Pin pitch is 1.27mm; body width is 3.9mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN2) | Input Channel 2 | Dedicated asynchronous input for second delay path; accepts standard 5V TTL/CMOS logic levels |
| 2 (GND) | Ground Reference | Common return for all inputs, outputs, and supply; must be low-inductance connection to minimize ground bounce |
| 3 (IN3) | Input Channel 3 | Third independent input; electrically isolated from IN1/IN2 to prevent crosstalk-induced jitter |
| 4 (IN1) | Input Channel 1 | Primary input for first delay path; symmetrical edge response preserves duty cycle fidelity |
| 5 (VCC) | +5V Supply | Power rail decoupling required within 1cm using ≥0.1µF ceramic capacitor to maintain delay stability |
| 6 (OUT1) | Output Channel 1 | Buffered 30ns-delayed replica of IN1; capable of driving 10 LS-TTL loads simultaneously |
| 7 (OUT2) | Output Channel 2 | Buffered 30ns-delayed replica of IN2; matched propagation delay ensures inter-channel skew <100ps |
| 8 (OUT3) | Output Channel 3 | Buffered 30ns-delayed replica of IN3; identical AC specs to OUT1/OUT2 for system-level timing uniformity |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates aging, humidity sensitivity, and thermal hysteresis found in ceramic or SAW delay lines |
| Precision edge matching | tPLH and tPHL both 30ns ±1.5ns - preserves input waveform symmetry and prevents duty cycle distortion |
| Three independent buffers | Each output isolates its channel electrically; no shared driver stage to avoid inter-channel coupling |
| Industrial temperature rating | Validated operation from -40°C to +85°C - suitable for motor drives, PLCs, and outdoor instrumentation |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-delay timing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1135Z-25+ | 25ns nominal delay, ±1.5ns initial tolerance, same SOIC-8 package and electrical specs | Suitable when 5ns shorter delay meets system timing budget; lower delay may reduce margin for trace-length mismatch compensation | Select DS1135Z-25+ only if 25ns satisfies worst-case setup/hold timing; verify skew correction remains sufficient. |
| DS1013N-30 | Discontinued 30ns delay line in 16-pin DIP; uses older bipolar process, higher ICC (50mA), wider delay tolerance (±5ns) | Limited to through-hole prototyping; not qualified for reflow or industrial temp; lacks edge symmetry preservation | DS1013N-30 is obsolete and unsuitable for new designs; DS1135Z-30 offers superior stability, smaller footprint, and modern assembly compatibility. |
Compared with DS1135Z-25+ and DS1013N-30, DS1135Z-30 uniquely delivers 30ns precision with ±1.5ns initial tolerance in a surface-mount SOIC-8 package, enabling compact, high-reliability timing alignment where legacy alternatives fail on stability, size, or manufacturability.

FAQ
What is the guaranteed delay accuracy of DS1135Z-30 over its full operating temperature range?
The DS1135Z-30 guarantees a total delay variation of ±2ns over -40°C to +85°C at VCC = 4.75V to 5.25V. This includes both initial tolerance (±1.5ns at +25°C) and additional drift due to temperature and voltage changes. All measurements are referenced to the 1.5V switching threshold under 15pF load, as defined in the official DS1135Z-30 datasheet.
Can DS1135Z-30 replace DS1013 or DS1035 in existing designs without layout changes?
Yes, DS1135Z-30 is a recommended drop-in replacement for DS1013 and DS1035 in SOIC-8 layouts. It shares identical pinout, 150-mil SO package dimensions, and 5V operation. However, verify that the 30ns delay value matches the original design intent, as DS1013/DS1035 offered different delay options. No PCB modifications are needed for physical fit or electrical interface.
Does DS1135Z-30 support 3.3V logic inputs or outputs?
No, DS1135Z-30 is specified only for +5V operation (4.75–5.25V). Its VIH minimum is 2.2V and VIL maximum is 0.8V, making it compatible with 5V TTL and CMOS logic families. It is not designed for direct interfacing with 3.3V systems; level-shifting circuitry is required if driven by or driving 3.3V devices.
What is the maximum capacitive load DS1135Z-30 can drive while maintaining specified delay and edge performance?
DS1135Z-30 is characterized and guaranteed for 15pF load capacitance, matching one 74F04 input gate. Driving loads >15pF will increase rise/fall times and may degrade delay accuracy beyond ±2ns specification. For heavier loads, add a local buffer; do not exceed 15pF at the DS1135Z-30 output pin without validation.
Is DS1135Z-30 RoHS compliant and suitable for lead-free reflow soldering?
Yes, DS1135Z-30 carries the "+" suffix indicating RoHS compliance. It is qualified for lead-free reflow soldering up to +260°C peak temperature (per JEDEC J-STD-020), and also supports vapor phase and wave soldering. The SOIC-8 package (S8+2 outline) meets IPC-7351B land pattern requirements for reliable assembly.
