Product details
Overview
DS1100Z-75 from Maxim Integrated is a 5-tap silicon delay line IC delivering precisely spaced 15ns, 30ns, 45ns, 60ns, and 75ns delays at each tap under 5V operation, with ±4ns tolerance over -40°C to +85°C, designed for digital timing alignment in high-speed logic systems such as clock skew correction and pulse shaping.
For engineers reviewing the DS1100Z-75 datasheet, DS1100Z-75 pinout, DS1100Z-75 application, or DS1100Z-75 equivalent, key selection criteria include tap delay accuracy across temperature, TTL/CMOS compatibility, 10 LS-load drive capability per tap, and SO-8 surface-mount packaging for space-constrained PCB layouts.
Technical Context
The DS1100Z-75 implements an all-silicon delay architecture with fixed, monotonic delay progression across five equally spaced taps-ensuring consistent relative timing between outputs. Each tap reproduces both leading and trailing edges with equal precision, measured at the 1.5V threshold under 5V ±5% supply.
It operates across industrial temperature range (-40°C to +85°C) with stable delay tolerance: ±4ns for ≤40ns delays (e.g., TAP1–TAP4), and ±13% for >40ns delays (e.g., TAP5 = 75ns). Input pulse width must exceed 20ns, and power-up time is 200μs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay Values (TAP1–TAP5) | 15ns / 30ns / 45ns / 60ns / 75ns - fixed, monotonic spacing enables precise multi-point timing alignment |
| Delay Tolerance (TAP1–TAP4) | ±4ns over -40°C to +85°C - ensures deterministic setup/hold margin in synchronous logic |
| Delay Tolerance (TAP5) | ±13% of 75ns (±9.75ns) - reflects percentage-based stability for longer delays |
| Supply Voltage | 4.75V to 5.25V - compatible with standard 5V TTL/CMOS logic rails without regulation |
| Output Drive Capability | 10 × 74LS loads per tap - sufficient for fanout into legacy logic families without buffering |
| Input Pulse Width (tWI) | ≥20ns - minimum pulse width to guarantee accurate delay propagation through all taps |
| Power-Up Time | 200μs - defines minimum reset-to-valid-output latency after VCC stabilization |
Pinout & Package
DS1100Z-75 is housed in an 8-pin SO (150 mils) surface-mount package, pin-compatible with industry-standard SOIC-8 footprints (land pattern 90-0096), RoHS-compliant (indicated by "+" suffix variants).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | +5V power supply input - requires local 0.1μF decoupling to ground for stable delay performance |
| 2 | TAP 1 | First delayed output - delivers 15ns delay with same edge fidelity as input |
| 3 | TAP 3 | Third delayed output - provides 45ns delay, aligned mid-sequence for intermediate timing points |
| 4 | TAP 5 | Fifth delayed output - delivers full 75ns delay, highest absolute delay in the series |
| 5 | IN | Digital input - accepts TTL/CMOS logic levels; 50Ω source impedance recommended |
| 6 | TAP 2 | Second delayed output - provides 30ns delay, enabling fine-grained step control |
| 7 | TAP 4 | Fourth delayed output - delivers 60ns delay, bridging major timing intervals |
| 8 | GND | Ground reference - shared return path for all I/O and supply currents |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates hybrid ceramic delay limitations - enables 100% wafer-level testability and long-term reliability |
| Equal tap spacing | Ensures linear delay progression (15ns steps) - simplifies timing budgeting in multi-stage logic paths |
| Leading- and trailing-edge accuracy | Guarantees matched tPLH/tPHL - critical for preserving pulse width integrity in delay-sensitive applications |
| TTL/CMOS compatibility | Accepts standard logic thresholds (VIH ≥ 2.2V, VIL ≤ 0.8V) - interoperable with mixed-logic systems |
| Vapor-phase, IR, and wave solderable | Supports all common SMT reflow profiles - no special process required for SO-8 assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100U-75 | Same electrical specs and delay values, but in 8-pin µMAX (3mm × 3mm) package instead of SO-8 | Better suited for ultra-dense layouts where board area is constrained; thermal resistance differs slightly | Select DS1100U-75 when footprint size is critical; DS1100Z-75 preferred for standard SO-8 assembly lines |
| DS1000S-75 | Hybrid (not all-silicon) construction; ±10% delay tolerance vs. ±4ns/±13%; higher power consumption (ICC ≈ 80mA) | Limited to commercial temp range (0°C to +70°C); not qualified for industrial environments | DS1100Z-75 offers superior stability, lower power, and extended temperature support - upgrade path from DS1000S-75 |
Compared with DS1100U-75 and DS1000S-75, DS1100Z-75 uniquely combines SO-8 manufacturability, industrial temperature rating, and tight ±4ns absolute delay tolerance - making it optimal for production-grade timing alignment where reliability and process compatibility are essential.

FAQ
What is the nominal delay of each tap on the DS1100Z-75?
The DS1100Z-75 provides five equally spaced delays: TAP1 = 15ns, TAP2 = 30ns, TAP3 = 45ns, TAP4 = 60ns, and TAP5 = 75ns. These values are specified at +25°C and 5V, with tolerances tightened to ±4ns for TAP1–TAP4 and ±13% for TAP5 across the full -40°C to +85°C operating range. Each value is guaranteed by Maxim's production test flow and documented in Table 1 of the DS1100 datasheet.
Is DS1100Z-75 compatible with 3.3V logic systems?
No, DS1100Z-75 is specified only for 5V operation (4.75V to 5.25V). Its input thresholds (VIH ≥ 2.2V, VIL ≤ 0.8V) and output drive characteristics are optimized for TTL/CMOS 5V logic families. Interfacing with 3.3V systems requires level translation; Maxim does not characterize or guarantee DS1100Z-75 performance below 4.75V.
Can DS1100Z-75 drive modern CMOS loads like 74LVC or 74AUC?
Yes - DS1100Z-75 specifies drive capability as "up to 10 × 74LS loads", which corresponds to ~1mA sink/source per tap. This exceeds the input current requirements of 74LVC and 74AUC families (typically < 10μA), making direct connection feasible. However, layout best practices (short traces, local decoupling) remain essential to preserve delay accuracy and edge fidelity.
Does DS1100Z-75 require external components for stable operation?
DS1100Z-75 requires only a 0.1μF ceramic capacitor between VCC (Pin 1) and GND (Pin 8), placed as close as possible to the device. No pull-up/down resistors, termination, or additional timing components are needed. The internal all-silicon design eliminates reliance on external RC networks or crystal references, simplifying BOM and layout.
What is the maximum input frequency supported by DS1100Z-75?
DS1100Z-75 has no hard maximum frequency limit, but its delay accuracy degrades near the practical pulse-width limit. With minimum input pulse width (tWI) of 20ns, the theoretical maximum repetition rate is 50MHz. However, the datasheet cautions that delay accuracy becomes application-sensitive above 1MHz due to layout and decoupling effects - so for precision timing, operation below 10MHz is recommended.
