Product details
Overview
DS1100Z-250+ from Maxim Integrated is a 5-tap silicon delay line IC delivering precise, fixed delays of 50ns, 100ns, 150ns, 200ns, and 250ns across equally spaced taps. It operates at 5V, supports -40°C to +85°C industrial temperature range, and reproduces both leading and trailing edges with ±4ns tolerance over full temperature range. It drives up to 10 LS-TTL loads per tap and is used in digital timing alignment, pulse shaping, and clock deskew circuits.
For engineers reviewing the DS1100Z-250+ datasheet, DS1100Z-250+ pinout, DS1100Z-250+ application, or DS1100Z-250+ equivalent, key selection considerations include tap delay accuracy over temperature, TTL/CMOS compatibility, SO-8 package footprint, 5V supply requirement, and edge-fidelity for synchronous signal conditioning.
Technical Context
The DS1100Z-250+ implements an all-silicon delay architecture with five fixed, monotonic delay stages-each tap's delay scales linearly from TAP1 (50ns) to TAP5 (250ns). Delay variation is unidirectional with temperature/voltage changes, ensuring consistent relative timing between taps.
It uses CMOS logic-level inputs and outputs, features 5V-only operation, and maintains ±4ns absolute delay tolerance over -40°C to +85°C for delays ≤40ns (scaled as ±13% for >40ns), with input-to-output propagation measured at 1.5V thresholds for both rising and falling edges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Tap Delays | TAP1=50ns, TAP2=100ns, TAP3=150ns, TAP4=200ns, TAP5=250ns - fixed, equally spaced delays for multi-stage timing alignment |
| Delay Tolerance | ±4ns (≤40ns taps) or ±13% (>40ns taps) over -40°C to +85°C - ensures predictable inter-tap skew in industrial environments |
| Supply Voltage | 4.75V to 5.25V - compatible with standard 5V logic rails and decoupling schemes |
| Input Compatibility | TTL/CMOS - accepts 0.8V/2.2V logic thresholds and drives 10 LS-TTL loads per tap |
| Operating Temp | -40°C to +85°C - qualified for industrial-grade embedded timing applications without derating |
| Power Consumption | 30–50mA active current at 1MHz - low static power enables use in power-constrained digital subsystems |
Pinout & Package
DS1100Z-250+ is housed in an 8-pin SOIC (150-mil) surface-mount package, pin-compatible with industry-standard SO-8 footprints and compatible with vapor-phase, IR, and wave soldering processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Digital Input | Accepts TTL/CMOS logic pulses; defines start point for all tap delays |
| 2 (TAP 1) | Delay Output | Delivers input signal delayed by 50ns; drives up to 10 LS-TTL loads |
| 3 (TAP 2) | Delay Output | Delivers input signal delayed by 100ns; same edge fidelity as TAP1 |
| 4 (TAP 3) | Delay Output | Delivers input signal delayed by 150ns; delay tracks monotonically with TAP1–TAP5 |
| 5 (GND) | Ground Reference | Logic and power ground return; required for stable delay accuracy and noise immunity |
| 6 (TAP 4) | Delay Output | Delivers input signal delayed by 200ns; maintains ±13% delay tolerance over full temp range |
| 7 (TAP 5) | Delay Output | Delivers input signal delayed by 250ns; final stage in fixed-delay chain |
| 8 (VCC) | Power Supply | +5V supply input; must be decoupled locally to minimize jitter and delay drift |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1000Z-250+ | Hybrid ceramic delay line; higher cost, larger footprint, lower reliability than all-silicon DS1100Z-250+ | Limited to commercial temp range (-20°C to +70°C); not rated for industrial environments | Select DS1100Z-250+ when long-term stability, smaller size, or extended temperature operation is required. |
| MAX9600ESE+ | Programmable 8-tap delay IC with adjustable step resolution (100ps–10ns); requires SPI configuration | Supports dynamic delay adjustment and fine-grained tuning-unsuitable for fixed, set-and-forget timing | Choose DS1100Z-250+ for simple, zero-config, low-power fixed-delay needs; MAX9600ESE+ only if programmability justifies added complexity. |
Compared with DS1000Z-250+, DS1100Z-250+ delivers superior reliability and industrial temperature support in a smaller SO-8 package; versus MAX9600ESE+, it offers immediate plug-and-play operation without firmware or configuration overhead-ideal for cost-sensitive, high-volume timing alignment.

FAQ
What is the nominal delay value for each tap of the DS1100Z-250+?
The DS1100Z-250+ provides five fixed, equally spaced delays: TAP1 = 50ns, TAP2 = 100ns, TAP3 = 150ns, TAP4 = 200ns, and TAP5 = 250ns. These values are factory-trimmed and specified at +25°C and 5V, with tolerance scaling based on delay magnitude and operating temperature per the datasheet's AC Electrical Characteristics table.
Does the DS1100Z-250+ support both rising and falling edge delays with equal accuracy?
Yes, the DS1100Z-250+ is explicitly designed to reproduce both leading and trailing edges with equal precision. Its tPLH (rising) and tPHL (falling) delays are matched within ±4ns for shorter delays and ±13% for longer delays, ensuring pulse-width integrity across all taps and operating conditions.
Can the DS1100Z-250+ operate outside the 5V supply range?
No-the DS1100Z-250+ is specified only for 4.75V to 5.25V operation. Absolute maximum ratings prohibit voltage below -0.5V or above +6.0V on any pin. Operation outside the 5V range invalidates delay specifications and may impair reliability or cause functional failure.
Is the DS1100Z-250+ pin-compatible with other DS1100 variants in SO-8 packaging?
Yes, all DS1100Z-xxx variants-including DS1100Z-250+-use identical 8-pin SOIC (150-mil) packaging and share the same pinout: IN, TAP1–TAP5, GND, VCC. The "+" suffix denotes lead(Pb)-free/RoHS compliance but does not affect pin assignment or electrical behavior.
What is the maximum capacitive load the DS1100Z-250+ can drive per tap?
The DS1100Z-250+ is rated to drive up to 10 LS-TTL loads per tap, equivalent to approximately 20pF total load capacitance under typical conditions. Exceeding this load increases propagation delay uncertainty and may degrade edge fidelity-designers should verify timing margins with actual board parasitics and termination.
