Product details
Overview
DS1100M-125+ from Maxim Integrated is a 5-tap silicon delay line IC with nominal tap delays of 25ns, 50ns, 75ns, 100ns, and 125ns; operates at 5V ±5%, supports -40°C to +85°C industrial temperature range, and drives up to 10 LS-TTL loads per tap-used in digital timing alignment, clock skew correction, and pulse width adjustment circuits.
For engineers reviewing the DS1100M-125+ datasheet, DS1100M-125+ pinout, DS1100M-125+ application, or DS1100M-125+ equivalent, key selection considerations include tap delay precision (±4ns over full temperature range), leading/trailing edge matching, TTL/CMOS compatibility, low-power CMOS operation, and SO-8 packaging with RoHS compliance.
Technical Context
The DS1100M-125+ implements an all-silicon fixed-delay architecture with five equally spaced output taps derived from a single input signal; each tap reproduces both logic state and edge transitions with matched propagation characteristics. Delay values are factory-trimmed and specified at 5V supply across -40°C to +85°C.
It features TTL/CMOS-compatible input thresholds (VIH ≥ 2.2V, VIL ≤ 0.8V), low active current (30–50mA typical), and robust solderability (vapor-phase, IR, and wave). Input-to-tap delay tolerance is ±4ns for delays ≤40ns and ±13% for delays >40ns over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Tap Delays | 25ns / 50ns / 75ns / 100ns / 125ns - fixed, equally spaced delays referenced to input rising/falling edges |
| Supply Voltage | 4.75V to 5.25V - ensures stable delay performance across standard 5V logic rails |
| Operating Temperature | -40°C to +85°C - qualified for industrial-grade embedded timing applications |
| Delay Tolerance | ±4ns (≤40ns taps), ±13% (>40ns taps) - defines worst-case timing margin for synchronous alignment |
| Output Drive | 12mA sink / -1mA source - sufficient to drive 10× 74LS loads without external buffering |
| Input Capacitance | 5–10pF - minimizes loading on preceding stage and preserves high-speed signal integrity |
Pinout & Package
DS1100M-125+ is housed in an 8-pin SO (150-mil) surface-mount package (package code S8+4, outline 21-0041), compatible with standard PCB assembly processes including reflow and wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | +5V power supply input - must be decoupled locally to suppress switching noise affecting delay stability |
| 2 | TAP 1 | First delayed output - delivers 25ns delay from input edge, TTL/CMOS-compatible voltage levels |
| 3 | TAP 3 | Third delayed output - delivers 75ns delay, matched edge fidelity to TAP 1 and TAP 5 |
| 4 | TAP 5 | Fifth delayed output - delivers 125ns delay, fully specified for leading and trailing edge accuracy |
| 5 | IN | Digital input - accepts TTL/CMOS logic signals; 5–10pF capacitance limits high-frequency rise time impact |
| 6 | TAP 2 | Second delayed output - delivers 50ns delay, unidirectionally tracked with other taps under temp/voltage variation |
| 7 | TAP 4 | Fourth delayed output - delivers 100ns delay, maintains equal edge precision across all operating conditions |
| 8 | GND | Ground reference - shared return path for all I/O and supply currents; critical for delay repeatability |

Use Value: Improves bit-error rate by reducing metastability window; matched edge delays prevent duty-cycle distortion in re-timed outputs. | Use Scenario: Generating precisely offset strobes and enable signals in automated test equipment (ATE) pattern generators. IC Role / Device Role / Timing Role: DS1100M-125+ supplies five deterministic delay references from a single master clock to calibrate channel timing offsets. Use Value: Achieves <100ps inter-channel skew consistency across temperature-essential for high-speed digital I/O validation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1000S-125+ | Hybrid ceramic delay line; higher aging drift, wider delay tolerance (±10%), no guaranteed leading/trailing edge match | Suitable only for non-critical, low-frequency timing where long-term stability is not required | Select DS1000S-125+ only if legacy design reuse mandates identical footprint and cost sensitivity outweighs precision needs |
| MAX9602ESE+ | Programmable 8-tap delay IC with adjustable step size (10ps–1ns); requires SPI configuration and external clock | Used when dynamic delay tuning or multi-channel synchronization is needed-not drop-in replacement | Choose MAX9602ESE+ for adaptive timing systems; DS1100M-125+ remains optimal for fixed, low-complexity delay tasks |
Compared with DS1000S-125+, DS1100M-125+ delivers tighter delay tolerance and superior edge fidelity at lower power; versus MAX9602ESE+, it offers simpler integration and zero configuration overhead for static delay requirements.

FAQ
What is the nominal delay value for each tap of the DS1100M-125+?
The DS1100M-125+ provides five equally spaced nominal delays: TAP 1 = 25ns, TAP 2 = 50ns, TAP 3 = 75ns, TAP 4 = 100ns, and TAP 5 = 125ns. These values are factory-trimmed and specified at 5V supply and +25°C, with tolerances tightened to ±4ns for shorter delays and ±13% for longer ones across the full -40°C to +85°C range. Each tap reproduces both leading and trailing edges with matched precision.
Is DS1100M-125+ compatible with 3.3V logic systems?
No, DS1100M-125+ is designed exclusively for 5V operation (4.75V to 5.25V). Its input thresholds (VIH ≥ 2.2V, VIL ≤ 0.8V) and output drive levels are optimized for TTL/CMOS 5V families. Interfacing with 3.3V logic requires level translation; the device does not support dual-supply or wide-VCC operation. Using it outside the 5V range may result in undefined timing behavior or reliability degradation.
Does DS1100M-125+ require external decoupling capacitors?
Yes, DS1100M-125+ requires local 0.1μF ceramic decoupling between VCC (Pin 1) and GND (Pin 8). This is essential to suppress supply noise induced by simultaneous tap switching, which could modulate delay values or introduce jitter. The datasheet specifies that measurements assume proper decoupling, and omission risks exceeding ±4ns delay tolerance-especially under fast input transitions or heavy capacitive loading.
Can DS1100M-125+ drive standard 74LS logic inputs directly?
Yes, DS1100M-125+ can drive up to 10 × 74LS loads per tap, as confirmed by its IOL = 12mA and IOH = -1mA specifications at VCC min. This capability is validated under standard test conditions with one 74F04-equivalent load, and the output voltage levels (VOH ≥ 4V, VOL ≤ 0.5V) meet 74LS input requirements. No series termination or buffering is needed for direct connection.
What is the meaning of the "M" in DS1100M-125+?
The "M" in DS1100M-125+ denotes the SO-8 (150-mil) package variant-consistent with Maxim's ordering nomenclature where "Z" also indicates SO-8, but "M" is used in certain distribution channels and tape-and-reel configurations. It is not a functional variant; DS1100M-125+ and DS1100Z-125+ share identical electrical specifications, pinout, and thermal performance. Both are RoHS-compliant ("+") and rated for -40°C to +85°C operation.
