Product details
Overview
DS1135Z-8+ from Maxim Integrated is a high-speed, all-silicon 3-channel logic delay line operating at +5V, delivering precise 8ns propagation delay per output (tPLH/tPHL) with ±1.0ns initial tolerance and ±1.5ns variation 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 clock skew management in digital test equipment.
For engineers reviewing the DS1135Z-8+ datasheet, DS1135Z-8+ pinout, DS1135Z-8+ application, or DS1135Z-8+ equivalent, key selection criteria include guaranteed 8ns delay matching across all three channels, industrial temperature support, 5V-only operation, and compatibility with vapor phase, IR, and wave soldering processes.
Technical Context
The DS1135Z-8+ implements three independent, fully buffered delay paths within a single silicon die-each path replicating input timing with identical 8ns tPLH/tPHL delay and matched rise/fall characteristics (tOR/tOF ≤ 2.5ns). Its architecture preserves input pulse symmetry by maintaining equal propagation for both leading and trailing edges.
No internal PLL, oscillator, or feedback loop is present; delay is fixed and deterministic, derived from calibrated on-die RC networks. The device operates strictly as a passive timing element-no configuration registers, no enable/disable control, and no power-down mode-making it suitable for deterministic signal alignment in high-reliability digital systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per output | 8ns (tPLH/tPHL), matched across all three channels for skew-critical signal alignment |
| Initial delay tolerance | ±1.0ns at +25°C/5.0V-enables tight setup/hold margin control in synchronous logic |
| Temp/voltage tolerance | ±1.5ns over -40°C to +85°C and 4.75–5.25V-guarantees stable timing in industrial environments |
| Output drive strength | 12mA sink / -1.0mA source-supports direct interface to 74F04-level TTL/CMOS loads |
| Rise/fall time | ≤2.5ns-minimizes jitter contribution and preserves fast-edge integrity |
| Supply voltage | +5V only (4.75–5.25V)-not compatible with 3V systems; see DS1135L for 3V variant |
| Power-up time | 100ms-stable delays established within 100ms after VCC application |
Pinout & Package
DS1135Z-8+ is housed in an 8-pin SOIC package (150-mil width, outline 21-0041), RoHS-compliant (indicated by '+' suffix), with gull-wing leads suitable for automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN2 | Second independent input channel-accepts TTL/CMOS-compatible logic signals |
| 2 | GND | Digital ground reference-must be low-impedance and decoupled near VCC pin |
| 3 | IN3 | Third independent input channel-electrically isolated from IN1/IN2 for multi-path timing |
| 4 | IN1 | First independent input channel-primary timing reference input |
| 5 | VCC | +5V supply-requires local 0.1µF ceramic decoupling to GND (Pin 2) |
| 6 | OUT1 | Buffered 8ns-delayed output of IN1-drives up to 10 LS loads |
| 7 | OUT2 | Buffered 8ns-delayed output of IN2-identical delay and drive to OUT1 |
| 8 | OUT3 | Buffered 8ns-delayed output of IN3-fully independent, matched delay path |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates quartz or analog RC drift-ensures long-term stability without aging or shock sensitivity |
| Precision edge matching | Identical tPLH and tPHL guarantee symmetrical delay for both rising and falling edges |
| Three independent buffered outputs | Enables simultaneous delay of three separate signals without crosstalk or loading interaction |
| Industrial temperature range | Validated operation from -40°C to +85°C-suitable for embedded instrumentation and factory automation |
| Solder process compatibility | Qualified for vapor phase, IR reflow, and wave soldering-supports high-yield manufacturing |
Applications

Use Value: Maintains setup/hold timing margins under voltage and temperature variation-critical for >100MHz parallel bus operation. | Use Scenario: Synchronizing opto-isolated sensor inputs to a central controller clock in noisy factory environments. IC Role / Device Role / Timing Role: Deterministic delay stage equalizing variable propagation through different isolation barriers. Use Value: Prevents metastability in sampled inputs by ensuring all channels arrive within one system clock period. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1135Z-6+ | 6ns fixed delay per channel; otherwise identical electrical and thermal specs | Used where shorter skew correction is required-e.g., shorter PCB traces or lower-frequency buses | Select when 6ns matches system timing budget; same footprint and drive capability |
| DS1135Z-10+ | 10ns fixed delay per channel; same tolerance, temp range, and output drive | Applied in longer interconnect scenarios-e.g., backplane routing or multi-board synchronization | Choose for extended delay needs; drop-in replacement with no layout change |
Compared with DS1135Z-6+ and DS1135Z-10+, the DS1135Z-8+ provides the optimal mid-range delay value for balancing skew correction and timing margin in 50–150MHz digital systems, while retaining full pin, thermal, and drive compatibility across the DS1135Z family.

FAQ
What is the exact delay value specified for DS1135Z-8+?
The DS1135Z-8+ delivers a nominal 8ns propagation delay for both tPLH (input rising to output rising) and tPHL (input falling to output falling) under all operating conditions. This value is guaranteed per Table 1 in the datasheet, with ±1.0ns initial tolerance at +25°C/5.0V and ±1.5ns total variation across -40°C to +85°C and 4.75–5.25V supply.
Is DS1135Z-8+ compatible with 3.3V logic systems?
No, DS1135Z-8+ is strictly a +5V device-its DC electrical characteristics (VIH = 2.2V min, VIL = 0.8V max) and AC timing are specified only for VCC = 4.75–5.25V. For 3.3V operation, Maxim specifies the DS1135L family; DS1135Z-8+ must not be used in 3.3V systems without level translation.
Does DS1135Z-8+ require external configuration or initialization?
No, DS1135Z-8+ is a fully static, zero-configuration delay line. It begins producing stable 8ns-delayed outputs within 100ms of VCC application (tPU), with no serial interface, registers, or enable pins. All three delay paths operate continuously and independently once powered.
Can DS1135Z-8+ drive standard TTL loads directly?
Yes, DS1135Z-8+ can directly drive up to 10 LS-TTL loads per output, as confirmed by its guaranteed output current specs: -1.0mA source (VOH = 4.0V) and 12mA sink (VOL = 0.5V) at VCC = 4.75V. This meets standard 74F04 input requirements without external buffering.
What is the package type and lead finish for DS1135Z-8+?
DS1135Z-8+ uses an 8-pin SOIC package (150-mil width, outline 21-0041) with RoHS-compliant matte tin lead finish (indicated by the '+' suffix). It is qualified for vapor phase, infrared reflow, and wave soldering per JEDEC standards.
