Product details
Overview
DS1135Z-12+ from Maxim Integrated is a high-speed, all-silicon 3-channel digital delay line operating at +5V, delivering precise 12 ns propagation delay per output (tPLH/tPHL), ±1.0 ns initial tolerance, and ±1.5 ns variation over -40°C to +85°C. It preserves input signal symmetry with matched leading/trailing edge accuracy and drives up to 10 LS-TTL loads-used in clock deskewing, pulse width adjustment, and timing alignment in industrial control logic.
For engineers reviewing the DS1135Z-12+ datasheet, DS1135Z-12+ pinout, DS1135Z-12+ application, or DS1135Z-12+ equivalent, key selection criteria include guaranteed 12 ns delay stability across voltage (4.75–5.25 V) and temperature, SOIC-8 package compatibility, and functional replacement path from legacy DS1013/DS1035 designs.
Technical Context
The DS1135Z-12+ implements three independent buffered delay paths within a single silicon die, each with identical 12 ns nominal tPLH/tPHL delay under 5 V supply and 25°C. Its architecture ensures symmetrical rise/fall delay matching (tOF/tOR ≤ 2.5 ns) and maintains input pulse integrity via low-jitter, edge-preserving buffering.
It operates across -40°C to +85°C with no external components required, supports vapor phase, IR, and wave soldering, and features active current draw ≤35 mA at 1 µs period-enabling integration into timing-critical digital systems without recalibration or trimming.
Key Specifications

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-10+ | 10 ns nominal delay, ±1.0 ns initial tolerance, otherwise identical AC/DC specs and pinout | Suitable where tighter delay budget allows 2 ns reduction; same PCB layout and thermal profile | Select when system timing margin permits shorter fixed delay without revalidation |
| DS1135Z-15+ | 15 ns nominal delay, ±1.5 ns temp/voltage tolerance, otherwise identical SOIC-8 packaging and drive capability | Used where longer delay is needed for setup/hold extension or signal isolation in noisy environments | Choose when 15 ns better matches trace-length mismatch or noise immunity requirements |
Compared with DS1135Z-10+ and DS1135Z-15+, the DS1135Z-12+ offers optimal balance of delay precision (±1.0 ns initial), thermal stability (±1.5 ns over full range), and compatibility with legacy DS1013/DS1035 footprints-making it the preferred choice for mid-range timing alignment tasks requiring deterministic 12 ns offset.

FAQ
What is the guaranteed delay accuracy of DS1135Z-12+ over its full operating temperature range?
The DS1135Z-12+ guarantees ±1.5 ns delay variation (tPLH/tPHL) across -40°C to +85°C and 4.75–5.25 V supply. This specification is measured at the 1.5 V switching threshold and covers both rising and falling edges, ensuring predictable timing margins in industrial environments without recalibration.
Can DS1135Z-12+ replace DS1013 in an existing design without PCB changes?
Yes, DS1135Z-12+ uses the same 8-pin SOIC (150-mil) package and identical pinout as DS1013, including IN1–IN3, OUT1–OUT3, VCC, and GND. No PCB modifications are required, and DS1135Z-12+ improves upon DS1013 with tighter delay tolerance and broader temperature operation.
Does DS1135Z-12+ support 3.3 V operation?
No, DS1135Z-12+ is specified only for +5 V operation (4.75–5.25 V). For 3 V systems, Maxim recommends the DS1135L family. Attempting 3.3 V operation on DS1135Z-12+ may result in undefined delay behavior, reduced noise margin, or failure to meet AC specifications.
What is the maximum input frequency supported by DS1135Z-12+?
DS1135Z-12+ supports input pulse periods down to 2× the tap delay (i.e., ≥24 ns period, or ≤41.7 MHz fundamental frequency), per AC Electrical Characteristics. Input pulse width must be ≥100% of tap delay (≥12 ns), and rise/fall times must be ≤3.0 ns (20%–80%) to maintain specified delay accuracy.
How many LS-TTL loads can each output of DS1135Z-12+ drive reliably?
Each DS1135Z-12+ output is rated to drive up to 10 LS-TTL loads under worst-case conditions (-40°C to +85°C, VCC = 4.75 V). This is confirmed by DC Electrical Characteristics specifying IOH ≥ -1.0 mA and IOL ≥ 12 mA at VOH = 4.0 V and VOL = 0.5 V, respectively.
