Product details
Overview
DS1004Z-2 from Dallas Semiconductor (now Maxim Integrated) is a 5-tap all-silicon delay line IC providing precise, temperature-stable tap-to-tap delays of 2 ns with ±0.75 ns nominal tolerance and ±1.5 ns over temperature/voltage. It delivers input-to-tap1 delay of 5 ns, supports CMOS/TTL logic levels, and drives up to 10 LS loads - used in high-speed digital timing alignment, clock deskewing, and pulse shaping circuits.
For engineers reviewing the DS1004Z-2 datasheet, DS1004Z-2 pinout, DS1004Z-2 application, or DS1004Z-2 equivalent, key selection criteria include tap delay accuracy, edge symmetry preservation, 8-pin SOIC (150-mil) package compatibility, and guaranteed 0°C to +70°C operation with 5 V ±5% supply.
Technical Context
The DS1004Z-2 implements a monolithic silicon delay chain with five buffered output taps, each precisely offset by fixed nominal delays (5/7/9/11/13 ns from input). Its architecture ensures matched propagation for rising and falling edges, preserving input signal symmetry with ≤0.5 ns edge skew.
It operates exclusively from a single +5 V supply, requires no external components, and maintains delay stability across voltage (4.75–5.25 V) and temperature (0–70°C), with input-to-tap1 tolerance of ±3.0 ns and tap-to-tap tolerance of ±1.5 ns under full operating conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Tap count | 5 independent delayed outputs (TAP1–TAP5) |
| Nominal tap-to-tap delay | 2 ns - enables fine-grained timing control for pulse spacing or phase alignment |
| Input-to-TAP1 delay | 5 ns - sets minimum latency before first delayed output is available |
| Delay tolerance (tap-to-tap) | ±0.75 ns nominal / ±1.5 ns over temp & voltage - ensures predictable inter-tap timing in production systems |
| Supply voltage | 4.75 V to 5.25 V - compatible with standard 5 V TTL/CMOS rails without regulation |
| Output drive strength | 12 mA sink / –1 mA source - sufficient to directly drive 10 LS-TTL loads without buffering |
| Operating temperature | 0°C to +70°C - suitable for commercial and industrial-grade embedded timing applications |
Pinout & Package
DS1004Z-2 is housed in an 8-pin SOIC package with 150-mil body width and standard gull-wing lead form. Pin pitch is 1.27 mm (0.050"), and the package is RoHS-compliant and vapor-phase/wave-solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input signal terminal | Accepts CMOS/TTL-compatible input; 10 pF input capacitance minimizes loading on driving stage |
| 2 (TAP1) | First delayed output | Delivers input signal delayed by 5 ns; fully buffered for fanout |
| 3 (TAP2) | Second delayed output | Delivers input signal delayed by 7 ns; matched edge timing preserves duty cycle |
| 4 (GND) | Ground reference | Primary return path for supply and signal currents; must be low-impedance for timing stability |
| 5 (VCC) | Positive supply | +5 V power rail; decoupling capacitor required at pin for noise immunity |
| 6 (TAP3) | Third delayed output | Delivers input signal delayed by 9 ns; identical drive capability as TAP1–TAP5 |
| 7 (TAP4) | Fourth delayed output | Delivers input signal delayed by 11 ns; symmetrical rise/fall times (2.0–2.5 ns) |
| 8 (TAP5) | Fifth delayed output | Delivers input signal delayed by 13 ns; final tap in chain; same AC specs as earlier taps |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates quartz aging, thermal drift, and mechanical shock sensitivity inherent in analog delay lines |
| Leading/trailing edge precision | Preserves input waveform symmetry - critical for clock deskew and pulse-width integrity |
| CMOS design with TTL compatibility | Interoperates directly with both 5 V CMOS and legacy TTL logic families without level-shifting |
| Vapor-phase, IR, and wave solderable | Supports automated PCB assembly across mainstream reflow and through-hole processes |
| 5-tap programmable delay resolution | Enables single-device implementation of multi-phase timing sequences (e.g., strobe generation, pipeline alignment) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 5-tap fixed-delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1004M-2 | Same electrical specs and delay values, but in 300-mil 8-pin DIP package instead of SOIC | Preferred for prototyping, through-hole assembly, or legacy board designs requiring DIP footprint | Select DS1004M-2 when manual soldering, breadboarding, or socket-based testing is required |
| MAX9995 | Single-output, digitally programmable delay (1–1000 ns); no multi-tap capability; higher power consumption | Suitable for variable-delay calibration, not fixed multi-phase timing | Choose MAX9995 only when dynamic delay adjustment is needed - not a functional replacement for DS1004Z-2's 5-tap architecture |
Compared with DS1004M-2, DS1004Z-2 offers identical timing performance in a surface-mount package for space-constrained layouts; compared with MAX9995, it provides deterministic multi-tap outputs at lower power and cost, but lacks programmability.

FAQ
What is the input-to-TAP1 delay specification for DS1004Z-2?
The DS1004Z-2 has a nominal input-to-TAP1 delay of 5 ns, with a tolerance of ±3.0 ns over the full operating temperature (0°C to +70°C) and supply voltage (4.75 V to 5.25 V) range. This value is confirmed in Table 1 of the official datasheet and applies identically to all DS1004Z-2 units regardless of batch or date code.
Does DS1004Z-2 support both rising and falling edge delays with equal accuracy?
Yes, DS1004Z-2 guarantees matched leading and trailing edge precision - both tPLH and tPHL delays are specified with identical tolerances (±1.5 ns over temperature/voltage). This symmetry preserves input duty cycle and is explicitly verified in the AC Electrical Characteristics table and Timing Diagram section of the DS1004Z-2 datasheet.
Can DS1004Z-2 operate from a 3.3 V supply?
No, DS1004Z-2 is specified only for 5 V operation (4.75 V to 5.25 V). It is not rated for 3.3 V use, and attempting to power it at that voltage will result in undefined timing behavior, reduced output drive, or failure to meet delay specifications. For 3.3 V systems, consider discrete delay solutions or level-shifting at the input/output.
What is the maximum capacitive load DS1004Z-2 can drive per output?
Each DS1004Z-2 output is characterized to drive up to 15 pF load capacitance while maintaining specified rise/fall times (2.0–2.5 ns) and delay accuracy. Driving heavier loads may increase propagation delay variation and degrade edge fidelity - for loads exceeding 15 pF, buffer amplification is recommended.
Is DS1004Z-2 pin-compatible with other DS1004 variants like DS1004Z-3 or DS1004Z-4?
Yes, all DS1004Z-x variants (x = 2, 3, 4, 5) share identical pinout, package, and DC/AC electrical characteristics - only the nominal tap-to-tap delay values differ. A DS1004Z-2 can be replaced with DS1004Z-3 on the same PCB without layout changes, provided the new delay profile meets system timing requirements.
