Product details
Overview
DS1135LZ-15+T&R from Maxim Integrated is a 3V, 8-pin SO all-silicon delay line delivering three independent buffered delays of precisely 15 ns each (tPLH/tPHL), with ±1.0 ns initial tolerance and ±4.0 ns total variation over -40°C to +85°C. It preserves input signal symmetry via leading/trailing edge precision and supports industrial-grade timing in high-speed logic interfaces.
For engineers reviewing the DS1135LZ-15+T&R datasheet, DS1135LZ-15+T&R pinout, DS1135LZ-15+T&R application, or DS1135LZ-15+T&R equivalent, this device serves as a RoHS-compliant, tape-and-reel packaged replacement for DS1033 in clock skew management, pulse width control, and digital signal alignment where sub-nanosecond edge fidelity and 3V operation are required.
Technical Context
The DS1135LZ-15+T&R implements three identical, fully buffered delay paths in a single monolithic silicon circuit-no external components required. Each path delivers matched 15 ns propagation delay (tPLH = tPHL = 15 ns) with ≤2.5 ns rise/fall time and maintains symmetry across temperature (-40°C to +85°C) and supply voltage (2.7V–3.6V).
Its architecture eliminates analog drift and aging effects typical of RC-based delay lines. Input-to-output delay is measured at 1.5 V threshold with 50 Ω source/load, and power-up stabilization occurs within 1 ms-enabling reliable use in hot-plug and power-cycled systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1135LZ-12+T&R | 12 ns nominal delay (vs. 15 ns); same package, tolerance, and temp range | Suitable where tighter delay budget exists but same edge fidelity and buffering required | Select when system timing analysis confirms 12 ns meets setup/hold margins |
| DS1135LZ-20+T&R | 20 ns nominal delay; ±2.5 ns tolerance over temp/volt (vs. ±4.0 ns for DS1135LZ-15+T&R) | Better delay stability at higher values-preferred for longer-skew compensation | Choose when greater delay resolution or improved temp stability at longer delays is needed |
Compared with DS1135LZ-12+T&R and DS1135LZ-20+T&R, the DS1135LZ-15+T&R offers the optimal balance of moderate delay value, tight initial tolerance (±1.0 ns), and proven industrial-temperature stability-making it ideal for mid-range skew correction and pulse shaping where 15 ns is the design target.

FAQ
What is the exact delay value and tolerance of DS1135LZ-15+T&R?
The DS1135LZ-15+T&R delivers a nominal delay of 15 ns on each of its three outputs (tPLH and tPHL). Its initial tolerance is ±1.0 ns at +25°C and 3.3 V. Over the full industrial temperature range (-40°C to +85°C) and supply voltage (2.7 V to 3.6 V), total delay variation is guaranteed within ±4.0 ns. This specification is confirmed in Table 1 of the official Maxim datasheet.
Is DS1135LZ-15+T&R pin-compatible with DS1033?
Yes, DS1135LZ-15+T&R is a recommended replacement for DS1033 and shares the same 8-pin SOIC (150-mil) package and pinout: IN1–IN3, GND, VCC, and OUT1–OUT3 occupy identical positions. However, DS1135LZ-15+T&R operates at 3V (vs. 5V for DS1033) and offers improved edge precision and temperature stability-requiring only supply voltage adaptation in legacy designs.
Does DS1135LZ-15+T&R support both rising and falling edge delays?
Yes, DS1135LZ-15+T&R guarantees matched 15 ns delay for both rising edges (tPLH) and falling edges (tPHL), preserving input signal symmetry and duty cycle. This dual-edge precision is explicitly specified in the datasheet's AC Electrical Characteristics and Delay Table, and is essential for applications like clock/data deskew and pulse width generation.
What is the maximum operating frequency supported by DS1135LZ-15+T&R?
DS1135LZ-15+T&R supports input pulse periods down to 2× the delay value (i.e., ≥30 ns minimum period), corresponding to a maximum fundamental frequency of ~33 MHz. Its 2.0–2.5 ns rise/fall time enables clean propagation of fast-edged signals up to ~200 MHz content, provided input pulse width meets the datasheet requirement of ≥100% of the 15 ns delay (i.e., ≥15 ns).
Can DS1135LZ-15+T&R be used with 2.5V or 3.3V supplies?
DS1135LZ-15+T&R is specified for operation from 2.7 V to 3.6 V. While it may function at 2.5 V, that voltage falls below the guaranteed minimum (2.7 V), risking increased delay variation and potential failure to meet timing specs. At 3.3 V, it operates within nominal conditions-delivering ±1.0 ns initial tolerance and full AC performance as characterized in the datasheet.
