Product details
Overview
DS1135Z-8/T&R from Maxim Integrated is a high-speed, all-silicon 3-channel digital delay line operating at +5V, delivering precise 8 ns propagation delay per output (tPLH/tPHL) with ±1.0 ns initial tolerance and ±1.5 ns tolerance over -40°C to +85°C. It features independent buffered outputs capable of driving 10 LS loads, leading/trailing edge symmetry preservation, and SOIC-8 (150-mil) packaging for industrial timing control applications.
For engineers reviewing the DS1135Z-8/T&R datasheet, DS1135Z-8/T&R pinout, DS1135Z-8/T&R application, or DS1135Z-8/T&R equivalent, this page provides verified timing accuracy, thermal/voltage stability data, SOIC-8 terminal mapping, and direct replacement guidance for legacy DS1013/DS1035 designs requiring sub-nanosecond edge fidelity and 5V-compatible logic interfacing.
Technical Context
The DS1135Z-8/T&R implements three independent, fully buffered delay paths in a single monolithic silicon IC-no external RC networks or crystal-based elements. Each channel delivers matched 8 ns nominal delay (tPLH = tPHL) with identical leading and trailing edge precision, preserving input signal symmetry across temperature and supply voltage variation (4.75 V–5.25 V).
It operates as a deterministic, zero-jitter propagation delay element-not a programmable oscillator or PLL-based timing generator. Its logic-level compatibility (VIH ≥ 2.2 V, VIL ≤ 0.8 V), fast 2.0–2.5 ns rise/fall times, and 100 ms power-up stabilization time define its role in high-fidelity digital signal alignment within synchronous bus interfaces and clock domain crossing circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per output | 8 ns (tPLH/tPHL), matched across all three channels for synchronized signal skew correction |
| Initial delay tolerance | ±1.0 ns at +25°C, 5.0 V - enables tight setup/hold margin control without calibration |
| Tolerance over temp/volt | ±1.5 ns (-40°C to +85°C, 4.75–5.25 V) - ensures stable timing in industrial environments |
| Output drive strength | 12 mA sink / -1.0 mA source at VOH=4.0 V/VOL=0.5 V - supports direct 74F04-equivalent loading |
| Rise/fall time | 2.0–2.5 ns - maintains signal integrity for >200 MHz edge rates in high-speed logic |
| Supply voltage | +5 V ±5% (4.75–5.25 V) - compatible with standard TTL/CMOS 5V systems |
| Power-up time | 100 ms - defines minimum reset-to-operational latency after VCC ramp |
Pinout & Package
DS1135Z-8/T&R is housed in an 8-pin SOIC package (150-mil width, outline 21-0041), RoHS-compliant, vapor-phase, IR, and wave solderable. Pin 1 is located at the top-left corner adjacent to the notch or dot marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN2 | Second independent input channel - accepts standard 5V logic signals for dedicated 8 ns delay path |
| 2 | GND | Digital ground reference - must be low-impedance connection to minimize delay jitter and crosstalk |
| 3 | IN3 | Third independent input channel - enables parallel triple-delay operation without external fanout |
| 4 | IN1 | Primary input channel - initiates first 8 ns delay path; pin position optimized for minimal trace length in layout |
| 5 | VCC | +5 V supply - requires local 0.1 µF ceramic decoupling per device to maintain delay stability |
| 6 | OUT1 | Buffered output for IN1 - delivers full-swing 5V logic with preserved edge symmetry and load drive capability |
| 7 | OUT2 | Buffered output for IN2 - electrically isolated from OUT1/OUT3 to prevent inter-channel coupling |
| 8 | OUT3 | Buffered output for IN3 - completes triple-output timing alignment with matched propagation characteristics |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates aging, drift, and environmental sensitivity inherent in RC or crystal-based delay solutions |

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-8+ | Same die, identical 8 ns delay and SOIC-8 package; "+" suffix denotes RoHS-compliant lead finish (vs. "/T&R" tape-and-reel packaging) | No functional difference - only packaging format differs (bulk vs. tape-and-reel); both support same thermal and electrical performance | Select DS1135Z-8/T&R for automated SMT production; choose DS1135Z-8+ for hand-solder prototyping or small-batch builds |
| DS1013-8 | Legacy bipolar implementation; higher ICC (50 mA), slower rise/fall (>4 ns), wider delay tolerance (±3 ns over temp), DIP-14 or SOIC-14 packaging | Larger footprint, higher power, lower precision - suitable only where legacy form factor or cost constraints override timing fidelity needs | DS1135Z-8/T&R offers superior edge fidelity and thermal stability but requires SOIC-8 layout; not pin-compatible with DS1013-8 |
Compared with DS1135Z-8+ and DS1013-8, the DS1135Z-8/T&R delivers best-in-class 8 ns delay accuracy and edge symmetry in a compact, production-ready tape-and-reel format-making it optimal for new industrial and test equipment designs demanding repeatable sub-nanosecond timing alignment.

FAQ
What is the guaranteed delay accuracy of DS1135Z-8/T&R over its full operating temperature range?
The DS1135Z-8/T&R guarantees ±1.5 ns delay tolerance (tPLH/tPHL) across -40°C to +85°C at VCC = 4.75 V to 5.25 V. This specification covers both leading and trailing edges and is measured at the 1.5 V switching threshold. Initial tolerance at +25°C is tighter at ±1.0 ns, enabling precise timing margin allocation during system design. The DS1135Z-8/T&R achieves this stability via all-silicon delay architecture with no external components required.
Can DS1135Z-8/T&R replace DS1013 or DS1035 in existing designs without layout changes?
No, DS1135Z-8/T&R cannot be used as a drop-in replacement for DS1013 or DS1035 due to differing packages and pin counts: DS1135Z-8/T&R uses an 8-pin SOIC, while DS1013 and DS1035 are offered in 14-pin DIP or SOIC packages. Although functionally similar as 3-channel delay lines, the pinout and footprint are incompatible. Redesign of the PCB land pattern and signal routing is required to integrate DS1135Z-8/T&R into legacy DS1013/DS1035-based systems.
What is the maximum capacitive load DS1135Z-8/T&R can drive while maintaining specified delay and edge performance?
The DS1135Z-8/T&R is characterized to drive one 74F04-equivalent input gate (≈15 pF load) while meeting all AC specifications including 2.0–2.5 ns rise/fall times and 8 ns delay accuracy. Driving heavier loads (>20 pF) will increase propagation delay and degrade edge rates beyond datasheet limits. For higher capacitance interfaces, external buffer amplification is recommended. The DS1135Z-8/T&R output stage is rated for 12 mA sink current, limiting practical load to ≤15 pF under standard test conditions.
Does DS1135Z-8/T&R support 3.3 V logic levels or require level-shifting circuitry?
The DS1135Z-8/T&R is strictly a +5 V device: it requires VCC = 4.75–5.25 V and has VIH(min) = 2.2 V and VIL(max) = 0.8 V. While it may accept 3.3 V logic inputs (since 3.3 V > 2.2 V), output swing is rail-to-rail 0–5 V, making direct interface with 3.3 V receivers unsafe without level translation. For 3.3 V systems, use the pin-compatible DS1135L series instead. DS1135Z-8/T&R is not 3.3 V tolerant and must be used in 5 V domains only.
Is DS1135Z-8/T&R suitable for use in automotive applications?
The DS1135Z-8/T&R is qualified for industrial temperature range (-40°C to +85°C) and meets JEDEC standards for SOIC packaging, but it is not AEC-Q200 qualified or automotive-grade screened. Its datasheet specifies no automotive-specific reliability testing (e.g., HTOL, TCT, ESD HBM >2 kV). For automotive applications, Maxim does not recommend DS1135Z-8/T&R; instead, consult ADI's automotive-qualified timing portfolio. DS1135Z-8/T&R remains appropriate for industrial, test, and computing environments meeting its specified operating conditions.
