Product details
Overview
DS1135Z-25 from Maxim Integrated is a high-speed, all-silicon 3-channel logic delay line operating at +5V, delivering precise 25ns propagation delay per output (tPLH/tPHL) with ±1.5ns initial tolerance and ±2ns tolerance 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 high-reliability timing alignment for digital test equipment.
For engineers reviewing the DS1135Z-25 datasheet, DS1135Z-25 pinout, DS1135Z-25 application, or DS1135Z-25 equivalent, key selection criteria include guaranteed 25ns delay stability across voltage (4.75–5.25V) and temperature, SOIC-8 package compatibility, and direct replacement capability for legacy DS1013/DS1035 designs requiring sub-ns edge precision.
Technical Context
The DS1135Z-25 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 aging inherent in LC or SAW-based delay solutions.
It operates with 50Ω source impedance, 15pF load capacitance, and 1.5V switching threshold-fully specified under IEEE 488-controlled automated test conditions using 20ps-resolution time interval analysis. Power-up stabilization completes within 100ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per output | 25ns ±1.5ns (initial), ±2ns (-40°C to +85°C) - ensures deterministic timing alignment across industrial temperature range |
| Supply voltage | +5V ±5% (4.75–5.25V) - compatible with standard 5V logic rails without regulation overhead |
| Input/output edge accuracy | Matched tPLH/tPHL - preserves input duty cycle and signal symmetry for clock/data recovery |
| Output drive strength | 12mA sink / -1mA source at VOH=4V/VOL=0.5V - supports direct interfacing to 74F04-level TTL loads |
| Input capacitance | 10pF max - minimizes loading on upstream drivers and maintains signal integrity at high frequencies |
| Power-up time | 100ms - defines minimum reset-to-stable-delay interval after VCC application |
Pinout & Package
DS1135Z-25 is housed in an 8-pin SOIC (150-mil) package, RoHS-compliant, vapor-phase, IR, and wave solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2, IN3 | Digital input signals | Three independent TTL-compatible inputs accepting 0.0–3.0V pulses; each routed to dedicated delay path |
| OUT1, OUT2, OUT3 | Delayed logic outputs | Buffered outputs delivering identical 25ns delay with matched rise/fall times (2.0–2.5ns) |
| VCC | Positive supply | +5V power rail connection; requires local 0.1µF decoupling per device |
| 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, humidity sensitivity, and thermal hysteresis found in analog delay elements |
| Precision edge matching | tPLH = tPHL within specification - enables zero-jitter data retiming in synchronous systems |
| Three independent delays | Single-package integration reduces board area and interconnect skew vs. discrete delay ICs |
| LS-TTL load drive | Each output drives 10 LS-TTL inputs directly - avoids need for external fanout buffers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-channel fixed-delay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1135Z-20+ | 20ns nominal delay, ±1.5ns temp/voltage tolerance | 5ns shorter delay; suitable where tighter timing budget allows reduced skew | Select when system timing margin permits 5ns less delay and identical package/pinout is required |

FAQ
What is the guaranteed delay accuracy of DS1135Z-25 over its full operating temperature range?
The DS1135Z-25 guarantees ±2ns delay tolerance over -40°C to +85°C, measured as tPLH and tPHL deviation from nominal 25ns. This includes combined effects of temperature, supply voltage (4.75–5.25V), and process variation. The specification is validated per Maxim's automated test setup using 20ps-resolution time interval analysis.
Can DS1135Z-25 replace DS1013 or DS1035 in existing designs without layout changes?
Yes, DS1135Z-25 is a recommended pin-compatible replacement for DS1013 and DS1035, sharing the same 8-pin SOIC (150-mil) package and identical pin assignment (IN1–IN3, OUT1–OUT3, VCC, GND). No PCB modifications are required, though users should verify 5V supply compatibility since DS1013/DS1035 may have different voltage ranges.
What load capacitance is assumed for DS1135Z-25 AC timing specifications?
DS1135Z-25 AC timing parameters-including tPLH, tPHL, tOR, and tOF-are specified with a 15pF capacitive load at each output, consistent with the equivalent of one 74F04 input gate. Driving heavier loads will increase propagation delay and degrade edge rates beyond datasheet limits.
Does DS1135Z-25 support both rising and falling edge delay matching?
Yes, DS1135Z-25 provides matched tPLH (rising-edge delay) and tPHL (falling-edge delay) within its ±1.5ns initial tolerance and ±2ns full-range tolerance. This edge symmetry preservation ensures minimal duty cycle distortion and is explicitly verified in the device's characterization methodology.
Is DS1135Z-25 compatible with lead-free reflow soldering processes?
Yes, DS1135Z-25 is rated for lead-free reflow soldering at +260°C (per JEDEC J-STD-020), and also supports vapor phase and wave soldering. The "Z" suffix denotes SOIC-150-mil packaging with RoHS-compliant terminations, confirmed in Maxim's package documentation.
