Product details
Overview
DS1004Z-2/T&R from Dallas Semiconductor is a 5-tap all-silicon delay line with nominal tap-to-tap delay of 2 ns, input-to-tap1 delay of 5 ns, ±0.75 ns nominal tap-to-tap tolerance, ±1.5 ns input-to-tap tolerance over temperature/voltage, and CMOS design with TTL compatibility - used in high-speed clock alignment and signal deskewing in test instrumentation and digital logic systems.
For engineers reviewing the DS1004Z-2/T&R datasheet, DS1004Z-2/T&R pinout, DS1004Z-2/T&R application, or DS1004Z-2/T&R equivalent, key selection criteria include precise edge-aligned multi-phase delay generation, 8-pin SOIC (150-mil) packaging, 5 V supply operation, 10 LS load drive capability, and tape-and-reel availability for automated assembly.
Technical Context
The DS1004Z-2/T&R implements a fixed, non-programmable analog delay chain delivering five precisely spaced output phases from a single CMOS/TTL-compatible input. Each tap provides deterministic propagation delay with matched rising/falling edge accuracy.
It operates at VCC = 5.0 V ±5% across 0°C to +70°C, supports 40% duty cycle inputs, and maintains ≤2.5 ns output rise/fall time into 15 pF load - enabling use in synchronous timing paths where skew control is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Tap-to-tap delay | 2 ns nominal - enables precise 2 ns step phase alignment between outputs |
| Input-to-tap1 delay | 5 ns - establishes baseline latency before first delayed output |
| Tap-to-tap tolerance | ±0.75 ns nominal - ensures sub-nanosecond inter-tap consistency at 25°C/5V |
| Input-to-tap tolerance | ±1.5 ns over temp/voltage - guarantees max 1.5 ns deviation across 0–70°C and 4.75–5.25V |
| Output drive strength | 12 mA sink / 1 mA source - sufficient to drive 10 LS-TTL loads without external buffering |
| Rise/fall time | ≤2.5 ns - preserves signal integrity for >200 MHz edge rates into 15 pF |
| Supply voltage | 4.75–5.25 V - compatible with standard 5 V logic rails and decoupling practices |
Pinout & Package
DS1004Z-2/T&R is housed in an 8-pin SOIC package with 150-mil body width and standard JEDEC MS-012AC footprint. Pin spacing is 1.27 mm (0.050"), and the device is vapor-phase, IR, and wave solder compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input signal terminal | Accepts CMOS/TTL-compatible 5 V logic input; 10 pF input capacitance minimizes loading on driving stage |
| 2 (TAP 1) | First delayed output | Delivers signal delayed by 5 ns from IN; matched edge symmetry preserves duty cycle |
| 3 (TAP 2) | Second delayed output | Delivers signal delayed by 7 ns from IN (i.e., +2 ns relative to TAP 1) |
| 4 (TAP 3) | Third delayed output | Delivers signal delayed by 9 ns from IN (i.e., +2 ns relative to TAP 2) |
| 5 (GND) | Ground reference | Single ground pin shared across all outputs; requires low-inductance PCB return path |
| 6 (VCC) | Power supply | +5 V supply pin; requires local 0.1 µF ceramic decoupling per device |
| 7 (TAP 4) | Fourth delayed output | Delivers signal delayed by 11 ns from IN (i.e., +2 ns relative to TAP 3) |
| 8 (TAP 5) | Fifth delayed output | Delivers signal delayed by 13 ns from IN (i.e., +2 ns relative to TAP 4) |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates quartz or SAW-based drift and aging; ensures stable delay over 10+ years in industrial environments |
| Precise leading/trailing edge matching | Maintains input waveform symmetry - critical for clock distribution and sampling window integrity |
| 5-tap fixed delay architecture | Provides deterministic, repeatable phase offsets without configuration overhead or startup delay |
| TTL/CMOS compatibility | Interfaces directly with 74F, 74LS, and modern 5 V logic families without level-shifting circuitry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 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 | Preferred for prototyping, through-hole assembly, or legacy board designs | Select DS1004M-2 when manual soldering or socket-based evaluation is required |
| MAX9992ESE+ | 5-tap, 2 ns step, but ±1.2 ns tap-to-tap tolerance and 3.3 V only operation | Suitable for mixed-voltage systems where 5 V is unavailable | Select MAX9992ESE+ only if 3.3 V supply and tighter layout constraints justify tolerance trade-off |
Compared with DS1004M-2 and MAX9992ESE+, the DS1004Z-2/T&R uniquely combines 150-mil SOIC packaging, 5 V operation, ±0.75 ns nominal tap-to-tap tolerance, and tape-and-reel readiness - making it optimal for automated production of compact, high-reliability timing modules.

FAQ
What is the nominal input-to-tap1 delay for DS1004Z-2/T&R?
The DS1004Z-2/T&R has a nominal input-to-tap1 delay of 5 ns, measured from the 1.5 V point on the input edge to the 1.5 V point on the TAP 1 output edge under standard conditions (25°C, VCC = 5.0 V). This value is fixed and unadjustable, and DS1004Z-2/T&R maintains this specification across its operating temperature and voltage range with ±1.5 ns total tolerance.
Does DS1004Z-2/T&R support both rising and falling edge delay accuracy?
Yes, DS1004Z-2/T&R delivers matched delay accuracy on both rising (tPLH) and falling (tPHL) edges, preserving input signal symmetry. The datasheet specifies identical nominal delays and tolerances for both edges, ensuring duty-cycle integrity across all five taps - a key requirement for clock distribution and sampling applications where edge alignment is critical. This behavior is inherent to its all-silicon delay architecture.
What is the maximum capacitive load DS1004Z-2/T&R can drive reliably?
DS1004Z-2/T&R is characterized to drive up to 10 LS-TTL loads, equivalent to approximately 15 pF at the output node. Its AC specifications - including ≤2.5 ns rise/fall time - are guaranteed under this load condition. Exceeding 15 pF may degrade edge speed and increase delay uncertainty; for heavier loads, external buffer amplification is recommended to maintain DS1004Z-2/T&R's specified timing performance.
Is DS1004Z-2/T&R pin-compatible with other DS1004 variants?
Yes, DS1004Z-2/T&R shares identical pinout and electrical behavior with all DS1004Z-x variants (x = 2, 3, 4, 5) and DS1004M-x variants in the same package type. All DS1004Z devices use the 150-mil 8-pin SOIC footprint with IN, TAP1–TAP5, VCC, and GND assigned to the same pins. However, DS1004Z-2/T&R is not pin-compatible with DS1004M-x due to differing package dimensions (SOIC vs. DIP), though functionally interchangeable where board space permits.
Can DS1004Z-2/T&R operate outside the 0°C to +70°C range?
No, DS1004Z-2/T&R is specified only for operation from 0°C to +70°C. Its delay tolerances, drive strength, and timing parameters are guaranteed within this commercial temperature range. While storage is rated from –55°C to +125°C, functional operation outside 0–70°C is not characterized or supported. For extended temperature applications, DS1004Z-2/T&R must be used within its qualified range or replaced with a thermally screened variant not offered in this family.
