Product details
Overview
DS1004Z-2+ from Analog Devices (acquired Dallas Semiconductor) is a 5-tap all-silicon delay line 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 in high-speed digital timing applications such as clock deskewing and signal alignment.
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, input-to-output delay stability across 0°C–70°C, and compatibility with standard 150-mil SOIC PCB layouts and automated assembly processes.
Technical Context
The DS1004Z-2+ implements a monolithic silicon delay architecture with five deterministic output taps derived from a single input clock. Each tap provides fixed, factory-trimmed propagation delay-tap1 at 5 ns, tap2 at 7 ns, tap3 at 9 ns, tap4 at 11 ns, and tap5 at 13 ns-under nominal conditions (VCC = 5.0 V ±5%, TA = 25°C).
It maintains leading and trailing edge precision to preserve input waveform symmetry, with tPLH/tPHL matching within ±0.75 ns (nominal) and ±1.5 ns (over full operating range). The device operates with TTL-compatible input thresholds (VIH ≥ 2.2 V, VIL ≤ 0.8 V) and delivers rail-to-rail CMOS outputs capable of sourcing/sinking ±1 mA/12 mA.
Key Specifications

| Nominal tap tolerance | ±0.75 ns; ensures sub-nanosecond repeatability for critical timing margins |
| Input-to-tap1 delay | 5 ns; establishes baseline latency for synchronized multi-tap signal distribution |
| Temp/volt delay drift | ±1.5 ns over 0°C–70°C and VCC = 4.75–5.25 V; guarantees stable timing in industrial environments |
| Output drive strength | 12 mA sink / 1 mA source; directly interfaces with 74F-series logic without buffering |
| Supply voltage | 4.75–5.25 V; compatible with standard +5 V regulated rails and legacy TTL systems |

Pinout & Package
DS1004Z-2+ is housed in a 150-mil 8-pin SOIC package (JEDEC MS-012), RoHS-compliant and vapor-phase/wave-solderable. Pin spacing is 1.27 mm, body width 3.9 mm, and total length 4.9 mm.

| 4 (TAP 3) | Third delayed output | Delivers input delayed by 9 ns; supports triple-phase alignment in burst-mode or pipelined logic |
| 5 (GND) | Ground reference | Common return path for all internal delay stages; requires low-inductance PCB connection to minimize ground bounce |
| 6 (VCC) | +5 V supply | Power rail for all delay elements; decoupling capacitor (0.1 µF) required within 5 mm of pin |
| 7 (TAP 4) | Fourth delayed output | Delivers input delayed by 11 ns; used for fourth-stage timing in multi-cycle setup/hold windows |
| 8 (TAP 5) | Fifth delayed output | Delivers input delayed by 13 ns; completes 5-tap sequence for maximum 8-ns span across outputs |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates quartz aging, thermal hysteresis, and mechanical shock sensitivity inherent in SAW/crystal-based delay lines |
| Edge symmetry preservation | Maintains identical tPLH and tPHL tolerances across all taps, ensuring duty cycle fidelity in regenerated clocks |
| 5-tap deterministic delay | Provides five fixed, non-programmable delays (5/7/9/11/13 ns) with guaranteed monotonic spacing for predictable timing analysis |
| TTL/CMOS dual compatibility | Accepts VIH ≥ 2.2 V and VIL ≤ 0.8 V inputs while driving CMOS-level outputs, enabling seamless integration into mixed-logic systems |

IC Role / Device Role / Timing Role: Generates five evenly spaced clock phases (5/7/9/11/13 ns) from one master clock for sequential activation. Use Value: Eliminates need for discrete RC networks or programmable delay ICs-reduces BOM count and layout complexity. |
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 delay values and tolerances, but in 300-mil 8-pin DIP package; higher thermal resistance and larger PCB footprint | Preferred for prototyping, through-hole assembly, or legacy DIP-based test fixtures | Select DS1004M-2+ when manual soldering or socket-based evaluation is required |
| MAX9995ETJ+ | 5-tap delay line with 1–10 ns programmable steps (100-ps resolution); higher power (120 mA ICC), 24-pin TQFN package | Suitable for adaptive delay tuning, not fixed-timing applications; requires SPI configuration and additional decoupling | Select MAX9995ETJ+ only when dynamic delay adjustment is mandatory and board space permits larger package |
Compared with DS1004M-2+ and MAX9995ETJ+, DS1004Z-2+ offers optimal balance of precision (±0.75 ns tap tolerance), compact SOIC packaging, and zero-configuration operation-making it ideal for volume production of fixed-skew timing solutions where reliability and assembly efficiency are critical.

FAQ
What is the nominal input-to-tap1 delay for DS1004Z-2+?
The DS1004Z-2+ has a nominal input-to-tap1 delay of 5 ns under standard conditions (VCC = 5.0 V ±5%, TA = 25°C). This value is fixed and unadjustable. Across the full operating temperature range (0°C to +70°C) and supply voltage variation (4.75 V to 5.25 V), the total delay tolerance is ±3.0 ns relative to nominal, per Dallas Semiconductor's published specifications for this part number.
Does DS1004Z-2+ support both rising and falling edge delays with equal accuracy?
Yes, DS1004Z-2+ preserves input symmetry with matched leading and trailing edge precision. Its tPLH (rising edge delay) and tPHL (falling edge delay) are specified with identical tolerances-±0.75 ns nominal and ±1.5 ns over temperature and voltage-ensuring duty cycle integrity across all five output taps.
Can DS1004Z-2+ drive standard TTL loads directly?
Yes, DS1004Z-2+ can drive up to 10 LS-TTL loads per output. Its IOL is rated at 12 mA (min) at VOL = 0.5 V, and IOH is –1.0 mA (min) at VOH = 4.0 V, meeting the DC interface requirements of 74LS-series logic. No external buffer is required for direct connection to legacy TTL systems.
What is the maximum operating frequency supported by DS1004Z-2+?
DS1004Z-2+ does not specify a maximum operating frequency; instead, it defines minimum input pulse width (tWI) as 40% of Tap5 tPLH, which is ~5.2 ns at nominal conditions. Based on AC electrical characteristics, reliable operation is confirmed for input periods ≥4 ns (≥250 MHz), provided rise/fall times remain ≤3.0 ns and load capacitance stays at 15 pF.
Is DS1004Z-2+ pin-compatible with DS1004M-2+?
DS1004Z-2+ and DS1004M-2+ share identical pin functions and signal assignments (IN, TAP1–TAP5, VCC, GND), but differ in package: DS1004Z-2+ uses 150-mil SOIC, while DS1004M-2+ uses 300-mil DIP. They are functionally identical and electrically interchangeable, though PCB layout must match the respective footprint.
