Product details
Overview
DS1033Z-8 from Dallas Semiconductor (now Maxim Integrated) is a low-voltage, all-silicon 3-channel delay line IC operating at 3.3 V with ±1.5 ns initial delay tolerance, 8 ns nominal delay per output, and precise leading/trailing edge preservation for signal integrity in timing-critical digital systems such as clock deskewing and bus synchronization.
For engineers reviewing the DS1033Z-8 datasheet, DS1033Z-8 pinout, DS1033Z-8 application, or DS1033Z-8 equivalent, key selection factors include its 8 ns fixed delay per channel, 2.7–3.6 V supply range, SOIC-8 (150-mil) package, ±1.0 ns temperature/voltage stability, and buffered TTL-compatible I/O performance.
Technical Context
The DS1033Z-8 implements three independent, identically delayed logic paths with matched tPLH/tPHL propagation delays of 8 ns each, measured at 1.5 V crossing under 3.3 V ±10% supply. Its all-silicon architecture eliminates quartz aging and thermal drift issues inherent in analog delay solutions.
Each input (IN1–IN3) drives a dedicated buffered output (OUT1–OUT3) with symmetrical rise/fall times (2.0–3.5 ns), 15 pF load capability, and guaranteed operation across 0°C to +70°C ambient - enabling deterministic timing in synchronous digital interfaces without external calibration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per output | 8 ns nominal; ensures precise, repeatable skew control across three parallel data or clock lines |
| Initial delay tolerance | ±1.5 ns at +25°C/3.3 V; defines worst-case static timing margin before temperature/voltage variation |
| Tolerance over temp/volt | ±1.0 ns (0°C to +70°C, 2.7–3.6 V); guarantees total delay deviation ≤ ±2.5 ns in full operating range |
| Supply voltage range | 2.7 V to 3.6 V; compatible with modern 3.3 V LVTTL and LVCMOS logic families |
| Output drive strength | IOL = 8 mA / IOH = –1 mA at VOL = 0.4 V / VOH = 2.0 V; sufficient to drive one 74F04 gate per output |
| Rise/fall time | 2.0–3.5 ns (1.5 V crossing, 15 pF load); preserves signal edge fidelity for high-speed sampling |
Pinout & Package
DS1033Z-8 is housed in an 8-pin SOIC (150-mil) package with standard JEDEC MS-012AC footprint, vapor-phase/reflow/wave solder compatible, and substrate-connected pins internally tied to GND (no external connection required).

| 2 (IN2) | Input signal B | Accepts TTL/LVCMOS logic-level waveform; drives second delay path |
| 3 (IN3) | Input signal C | Accepts TTL/LVCMOS logic-level waveform; drives third delay path |
| 4 (GND) | Ground reference | Primary return path for supply and signal currents; connects to PCB ground plane |
| 5 (VCC) | Power supply | +2.7 V to +3.6 V DC input; requires local 0.1 µF bypass capacitor near pin |
| 6 (OUT3) | Delayed output C | Delivers IN3 signal delayed by 8 ns; TTL-compatible buffered output |
| 7 (OUT1) | Delayed output A | Delivers IN1 signal delayed by 8 ns; TTL-compatible buffered output |
| 8 (OUT2) | Delayed output B | Delivers IN2 signal delayed by 8 ns; TTL-compatible buffered output |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1033M-8 | DIP-8 package instead of SOIC-8; identical electrical specs and 8 ns delay | Suitable for through-hole prototyping or legacy board designs requiring DIP footprint | Select DS1033M-8 only when manual assembly or socket-based evaluation is required |
| MAX9992ETA+ | Single-channel, adjustable 0–10 ns delay via external resistor; higher power (30 mA ICC) | Used where programmable delay or fine-tuning is needed, not fixed 8 ns matching | Choose MAX9992ETA+ only if dynamic delay adjustment or single-line correction is required |
Compared with DS1033Z-8, DS1033M-8 offers identical timing performance in a through-hole package, while MAX9992ETA+ trades fixed triple-channel precision for programmability and higher current draw - making DS1033Z-8 optimal for cost-sensitive, space-constrained, and skew-matched multi-signal applications.

FAQ
What is the exact delay value and tolerance specification for DS1033Z-8?
The DS1033Z-8 provides a nominal delay of 8 ns per output (tPLH and tPHL), with an initial tolerance of ±1.5 ns at +25°C and 3.3 V. Over the full operating range (0°C to +70°C, 2.7–3.6 V), additional tolerance is ±1.0 ns, resulting in a total worst-case delay deviation of ±2.5 ns. This is confirmed in Table 1 of the official DS1033 datasheet.
Does DS1033Z-8 support operation at 2.5 V supply voltage?
No, DS1033Z-8 is specified only for 2.7 V to 3.6 V operation. At 2.5 V, the device falls outside its Absolute Maximum Ratings and DC Electrical Characteristics - parameters including output drive strength, delay accuracy, and logic threshold compliance are not guaranteed. Operation below 2.7 V may result in functional failure or increased delay uncertainty.
Can DS1033Z-8 be used with 5 V logic inputs?
Yes - DS1033Z-8 accepts 5 V-tolerant inputs: VIH is specified up to VCC + 0.5 V, and absolute maximum input voltage is +6.0 V. With VCC = 3.3 V, a 5 V input remains within safe operating limits and meets the VIH minimum of 2.0 V. However, output levels remain 3.3 V compliant and must interface accordingly.
Is the substrate pin (pin 4 in DIP, internal in SOIC) required to connect externally for DS1033Z-8?
No - the substrate connection in DS1033Z-8 is internal and tied to GND. External connection to this node is explicitly prohibited per the datasheet. In the SOIC-8 package, no dedicated substrate pin exists; the internal substrate is bonded to the leadframe ground plane, which connects to pin 4 (GND). No additional grounding is needed beyond standard GND routing.
How does DS1033Z-8 compare to RC-based delay circuits in terms of temperature stability?
DS1033Z-8 delivers ±1.0 ns delay variation over 0°C to +70°C, whereas typical RC networks exhibit >1000 ppm/°C drift - translating to >800 ps/°C error for an 8 ns delay. The all-silicon design of DS1033Z-8 eliminates capacitor dielectric aging and resistor TCR effects, providing orders-of-magnitude better stability and repeatability than passive solutions across voltage and temperature.
