Product details
Overview
DS1100M-75+ from Maxim Integrated is a 5-tap silicon delay line IC delivering precise, fixed delays of 15ns, 30ns, 45ns, 60ns, and 75ns across equally spaced taps, operating at 5V with TTL/CMOS compatibility and ±4ns delay tolerance over -40°C to +85°C, used in digital timing alignment and signal skew correction in high-speed logic systems.
For engineers reviewing the DS1100M-75+ datasheet, DS1100M-75+ pinout, DS1100M-75+ application, or DS1100M-75+ equivalent, key selection considerations include tap delay accuracy, edge fidelity for both rising/falling transitions, 5V supply compliance, SO-8 vs. µMAX-8 package trade-offs, and load-driving capability up to 10 × 74LS loads per tap.
Technical Context
The DS1100M-75+ implements an all-silicon delay architecture with five fixed-output taps referenced to a single input, where each tap reproduces the input logic state after its nominal delay (15/30/45/60/75ns), with unidirectional delay variation across temperature and voltage-ensuring monotonic tracking between taps.
It supports precise edge-aligned timing via 1.5V-level delay measurement, maintains leading- and trailing-edge accuracy within ±4ns over industrial temperature range, and features low-power CMOS design with active current ≤50mA at 1MHz, enabling integration into noise-sensitive digital control and test instrumentation circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Tap Delays | 15ns / 30ns / 45ns / 60ns / 75ns - fixed, equally spaced delays for multi-point timing synchronization |
| Delay Tolerance | ±4ns (≤40ns taps) or ±13% (>40ns taps) over -40°C to +85°C - ensures predictable skew management |
| Supply Voltage | 4.75V to 5.25V - compatible with standard 5V logic rails without regulation overhead |
| Input Compatibility | TTL/CMOS - accepts 0.8V/2.2V logic thresholds, simplifying interface with legacy and modern logic families |
| Output Drive | 12mA sink / -1mA source - sufficient to drive 10 × 74LS loads per tap without buffering |
| Operating Temperature | -40°C to +85°C - qualified for industrial-grade embedded timing applications |
| Power-Up Time | 200μs - enables stable operation after power rail stabilization, critical for cold-start systems |
Pinout & Package
DS1100M-75+ is housed in an 8-pin µMAX® package (U8+1 footprint, 3mm × 3mm, 0.65mm pitch), pin-compatible with industry-standard SO-8 but offering 40% smaller PCB area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Signal Input | Accepts single-ended logic input; triggers all five delay paths simultaneously |
| TAP 1–TAP 5 | Delayed Output Taps | Provide fixed-delay replicas of IN; outputs are independent and fan-out capable |
| VCC | Positive Supply | +5V power rail connection; decoupling required within 1cm for timing stability |
| GND | Ground Reference | Common return path for all signals and supply; must be low-impedance for jitter control |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay core | Eliminates hybrid ceramic or SAW-based drift; delivers stable delay over time and thermal cycling |
| Equal tap spacing | Enables linear interpolation or uniform clock phase stepping in delay-chain configurations |
| Leading- and trailing-edge accuracy | Ensures matched propagation for both edges-critical for pulse-width integrity in timing-critical logic |
| Vapor-phase, IR, and wave solderable | Supports full automated PCB assembly without rework risk or reliability degradation |
| RoHS-compliant "+" suffix | Meets EU Directive 2011/65/EU; lead-free terminations with SnAgCu finish |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100Z-75+ | Same electrical specs and delay values, but in 8-pin SO-8 package (S8+4) instead of µMAX-8 | Requires larger PCB footprint; better thermal dissipation and hand-solderability | Select DS1100Z-75+ when board space allows and manual rework or thermal margin is prioritized |
| MAX9601EUA+ | Single-output, adjustable delay (0–100ns) with fine resolution (10ps step); higher power, different architecture | Used for dynamic delay tuning rather than fixed multi-tap distribution | Select MAX9601EUA+ only when programmable delay and single-output precision outweigh need for five simultaneous taps |
Compared with DS1100M-75+, DS1100Z-75+ offers identical timing performance in a larger SO-8 package, while MAX9601EUA+ provides tunable delay at the cost of fixed-tap functionality-making DS1100M-75+ optimal for static, multi-point skew correction where compactness and tap count are essential.

FAQ
What is the exact delay value for each tap of the DS1100M-75+?
The DS1100M-75+ provides five fixed delays: TAP 1 = 15ns, TAP 2 = 30ns, TAP 3 = 45ns, TAP 4 = 60ns, and TAP 5 = 75ns. These values are nominal at +25°C and 5V, with tolerances of ±4ns for delays ≤40ns and ±13% for delays >40ns over the full -40°C to +85°C range. All delays track monotonically with temperature and voltage changes.
Is the DS1100M-75+ pin-compatible with other DS1100 variants?
Yes, the DS1100M-75+ uses the 8-pin µMAX package (U8+1), which shares identical pinout with all DS1100U-xxx variants. It is not pin-compatible with DS1100Z-xxx (SO-8), though both share the same terminal functions and numbering. The pin assignment-IN, TAP1–TAP5, VCC, GND-is consistent across the DS1100 family.
Does the DS1100M-75+ support both rising and falling edge delays?
Yes, the DS1100M-75+ reproduces both leading and trailing edges with equal precision. Delay is measured at the 1.5V threshold for both tPLH (rising) and tPHL (falling), and the datasheet specifies identical tolerance for both edges-ensuring pulse-width preservation across all five taps.
What is the maximum capacitive load the DS1100M-75+ can drive per tap?
The DS1100M-75+ is rated to drive up to 10 × 74LS loads per tap, equivalent to ~1000pF total load capacitance under typical conditions. Output drive strength is specified as IOL = 12mA (sink) and IOH = -1mA (source) at VCC = 4.75V, supporting direct interfacing with standard TTL/CMOS inputs without external buffers.
How does the DS1100M-75+ differ from the older DS1000 series?
The DS1100M-75+ is an improved replacement for the DS1000, featuring all-silicon construction (vs. hybrid), tighter delay tolerances, enhanced edge fidelity, lower power consumption, and RoHS-compliant packaging. Unlike the DS1000, it guarantees monotonic delay tracking across taps and operates reliably over the full industrial temperature range without derating.
