Product details
Overview
DS1033M-8 from Maxim Integrated (formerly Dallas Semiconductor) is a low-voltage, all-silicon 3-channel digital delay line with ±1.5 ns initial delay tolerance, 8 ns nominal per-output delay, and operation over 2.7V–3.6V supply range. It preserves input signal symmetry via precise leading/trailing edge timing and is housed in an 8-pin PDIP package for through-hole mounting in timing-critical logic interfaces.
For engineers reviewing the DS1033M-8 datasheet, DS1033M-8 pinout, DS1033M-8 application, or DS1033M-8 equivalent, key selection criteria include guaranteed 8 ns delay accuracy across temperature (0°C to +70°C), independent buffered outputs, VCC=3.3V compatibility, and DIP-8 footprint suitability for legacy test fixtures and prototyping boards.
Technical Context
The DS1033M-8 implements three independent CMOS-buffered delay paths within a single monolithic silicon die, each delivering identical 8 ns propagation delay (tPLH/tPHL) under nominal conditions (25°C, VCC=3.3V). Its architecture avoids analog RC or LC elements, eliminating drift and enabling stable performance across voltage and temperature.
Each channel features matched rise/fall time (2.0–3.5 ns), supports 100% tap delay pulse width, and maintains input-to-output edge fidelity without duty cycle distortion. The device draws ≤25 mA active current at VCC=3.6V and requires no external components for basic operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1033Z-8 | Same 8 ns delay, but in 8-pin SOIC (150-mil); RoHS-non-compliant; identical electrical specs | Suitable for surface-mount production; not interchangeable without PCB redesign | Select DS1033Z-8 only when migrating to SMT assembly and layout allows SOIC footprint |
| DS1033M-10 | Identical package and pinout, but 10 ns nominal delay; ±1.5 ns initial tolerance; same temp/voltage specs | Used where longer delay is required-no change to board or interface logic | Choose DS1033M-10 if system timing budget permits 2 ns additional latency and tighter skew margin is unnecessary |
Compared with DS1033Z-8 and DS1033M-10, the DS1033M-8 uniquely satisfies designs requiring exactly 8 ns delay in a through-hole DIP-8 package, offering direct replacement for legacy test hardware and avoiding both SMT conversion and delay-value overdesign.

FAQ
What is the nominal delay value of the DS1033M-8?
The DS1033M-8 provides a nominal delay of 8 ns for each of its three independent outputs (tPLH and tPHL). This value is specified under nominal conditions: TA = +25°C and VCC = +3.3 V. Delay remains stable across the full operating temperature range (0°C to +70°C) and supply voltage range (2.7V to 3.6V), with added tolerance of ±1.0 ns over temperature and voltage for this speed grade. The DS1033M-8 achieves this using monolithic silicon delay circuitry-not RC networks-ensuring consistent performance.
Does the DS1033M-8 require external components to operate?
No, the DS1033M-8 operates autonomously with only a decoupling capacitor recommended on the VCC pin (0.1 µF ceramic, placed close to pin 5). It contains fully integrated CMOS buffers and delay elements, needing no external resistors, capacitors, or crystals. Input signals must meet VIH ≥ 2.0 V and VIL ≤ 0.8 V under specified VCC conditions, and outputs drive standard 74F04-equivalent loads directly. The DS1033M-8 is designed for plug-and-play integration into timing-critical logic paths.
Is the DS1033M-8 pin-compatible with other DS1033M variants?
Yes, all DS1033M-x variants-including DS1033M-8, DS1033M-10, DS1033M-12, and DS1033M-20-share identical 8-pin PDIP pinout, package dimensions, and terminal functions. Only the nominal delay value differs between variants; electrical characteristics (supply range, temperature rating, drive strength, and timing tolerances) are otherwise consistent. This allows direct substitution during design iteration or field upgrade without PCB changes-provided the new delay value meets system timing constraints. The DS1033M-8 is fully interchangeable in footprint and interface with these variants.
What is the maximum output load the DS1033M-8 can drive?
The DS1033M-8 is characterized to drive one 74F04 input gate per output, equivalent to ~15 pF capacitive load and ≤1 mA DC current. Its IOL is specified at 8 mA (VCC = 2.7 V, VOL = 0.4 V) and IOH at –1 mA (VCC = 2.7 V, VOH = 2.0 V). Driving heavier loads may degrade rise/fall times and delay accuracy. For higher fanout, buffer stages should be added externally. The DS1033M-8's output stage is optimized for signal integrity-not power delivery-making it ideal for point-to-point timing alignment rather than bus driving.
Can the DS1033M-8 be used in automotive applications?
No, the DS1033M-8 is rated for commercial temperature range only (0°C to +70°C) and is not qualified for automotive AEC-Q100 stress testing. Its absolute maximum ratings and characterization data do not extend to extended temperature ranges (–40°C to +125°C) or automotive-grade reliability requirements. While some customers have deployed it in controlled cabin environments, Maxim does not guarantee performance outside the published 0°C to +70°C operating range. For automotive timing applications, consider purpose-qualified alternatives. The DS1033M-8 remains appropriate for industrial, test, and commercial embedded systems meeting its spec limits.
