Product details
Overview
DS1100M-350+ from Maxim Integrated is a 5-tap silicon delay line IC delivering precisely spaced 7ns, 14ns, 21ns, 28ns, and 35ns delays at 5V supply, with ±4ns tolerance over –40°C to +85°C, TTL/CMOS-compatible outputs, and capability to drive up to 10 × 74LS loads - used in digital timing alignment, clock skew correction, and pulse-width shaping circuits.
For engineers reviewing the DS1100M-350+ datasheet, DS1100M-350+ pinout, DS1100M-350+ application, or DS1100M-350+ equivalent, key selection considerations include tap delay precision across temperature, leading/trailing edge matching, SO-8 vs. µMAX-8 package compatibility, and replacement suitability for legacy DS1000-series hybrid delay lines.
Technical Context
The DS1100M-350+ implements an all-silicon delay architecture with five fixed, equally spaced output taps derived from a monolithic CMOS delay chain. Each tap reproduces both rising and falling edges with matched propagation delay (tPLH/tPHL), enabling precise edge-aligned signal replication without duty-cycle distortion.
It operates exclusively at 5V (4.75V–5.25V), supports input pulse widths ≥500ns, and maintains stable delay accuracy under industrial temperature conditions (–40°C to +85°C) with no external components required. Delay tolerances are specified as ±4ns for ≤40ns delays and ±13% for >40ns delays across full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Tap Delays | 7ns / 14ns / 21ns / 28ns / 35ns - fixed, equally spaced delays referenced to input edge at 1.5V threshold |
| Delay Tolerance | ±4ns (–40°C to +85°C) - ensures timing margin control in industrial clock alignment applications |
| Supply Voltage | 4.75V–5.25V - compatible with standard 5V logic rails; no regulation required |
| Output Drive | 12mA sink / –1mA source - sufficient to directly drive 10 × 74LS inputs without buffering |
| Input Capacitance | 5–10pF - low loading enables clean edge integrity on high-speed logic inputs |
| Operating Temp | –40°C to +85°C - qualified for industrial-grade embedded timing systems |
| Power-Up Time | 200μs - defines minimum reset-to-valid-output latency after VCC stabilization |
Pinout & Package
DS1100M-350+ is packaged in an 8-pin µMAX (U8+1) surface-mount package - 3mm × 3mm body, 0.65mm pitch, RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Logic Input | Accepts TTL/CMOS-compatible 5V signals; 5–10pF input capacitance minimizes reflection and jitter |
| 2 (TAP 1) | First Delay Output | Delivers input signal delayed by 7ns; matches tPLH/tPHL within ±4ns over full temperature range |
| 3 (TAP 2) | Second Delay Output | Delivers input signal delayed by 14ns; unidirectional delay drift ensures monotonic tap spacing |
| 4 (TAP 3) | Third Delay Output | Delivers input signal delayed by 21ns; identical edge fidelity to TAP 1 and TAP 2 |
| 5 (TAP 4) | Fourth Delay Output | Delivers input signal delayed by 28ns; capable of driving 10 × 74LS loads simultaneously |
| 6 (TAP 5) | Fifth Delay Output | Delivers input signal delayed by 35ns; final tap in fixed 5-tap sequence; same AC specs as prior taps |
| 7 (GND) | Ground Reference | Single ground pin for all internal circuitry and output drivers; requires low-inductance PCB connection |
| 8 (VCC) | Power Supply | +5V supply input; decoupling capacitor (0.1μF) recommended within 5mm of pin for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates hybrid ceramic delay line reliability risks and enables vapor-phase, IR, and wave soldering |
| Leading- and trailing-edge matching | tPLH and tPHL match within ±4ns - critical for preserving pulse width in timing-critical logic paths |
| Five equally spaced taps | Fixed 1:2:3:4:5 delay ratio (7ns increments) - simplifies multi-phase clock generation and skew compensation |
| TTL/CMOS compatibility | VIH = 2.2V min, VIL = 0.8V max - interoperable with 74LS, 74HC, and mixed-logic systems without level shifters |
| Industrial temperature rating | Specified performance from –40°C to +85°C - suitable for automotive infotainment timing and industrial PLC I/O modules |
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-350+ | Same electrical specs and delay values, but in 8-pin SO (150 mil) package instead of µMAX | Requires larger PCB footprint (4.9mm × 3.9mm vs. 3mm × 3mm); better thermal dissipation in high-power density layouts | Select DS1100Z-350+ when board space allows and SO-8 assembly infrastructure is already in place |
| DS1000S-350+ | Hybrid ceramic delay line; ±10ns tolerance over temperature; higher power consumption; not RoHS-compliant | Limited to commercial temp range (0°C to +70°C); incompatible with modern lead-free reflow profiles | DS1100M-350+ replaces DS1000S-350+ in new designs requiring industrial temp support and RoHS compliance |
Compared with DS1100Z-350+ and DS1000S-350+, the DS1100M-350+ offers identical delay performance in a smaller, RoHS-compliant µMAX package with guaranteed industrial temperature operation - making it optimal for space-constrained, high-reliability embedded timing applications.

FAQ
What is the nominal delay value for each tap of the DS1100M-350+?
The DS1100M-350+ provides five equally spaced delays: TAP 1 = 7ns, TAP 2 = 14ns, TAP 3 = 21ns, TAP 4 = 28ns, and TAP 5 = 35ns - all referenced to the 1.5V input threshold crossing point. These values are fixed and factory-trimmed; no external adjustment is possible. The "350" in DS1100M-350+ denotes the total delay (35ns) at TAP 5.
Does the DS1100M-350+ support both rising and falling edge delays with equal accuracy?
Yes, the DS1100M-350+ guarantees matched tPLH (rising edge) and tPHL (falling edge) delays within ±4ns over –40°C to +85°C. This edge symmetry preserves pulse width integrity and eliminates duty-cycle distortion - a key requirement in clock distribution and data retiming applications using DS1100M-350+.
Can the DS1100M-350+ drive standard TTL loads directly?
Yes, each tap of the DS1100M-350+ can drive up to 10 × 74LS loads without external buffering. Its IOL = 12mA and IOH = –1mA specifications meet TTL fan-out requirements. For heavier loads or longer traces, local decoupling and impedance-controlled routing are recommended to maintain DS1100M-350+ timing accuracy.
What is the operating voltage range for the DS1100M-350+?
The DS1100M-350+ operates from 4.75V to 5.25V at VCC. It is not rated for 3.3V operation. Supply voltage stability directly affects delay accuracy: ±5% VCC variation contributes to the overall ±4ns delay tolerance budget. A 0.1μF ceramic decoupling capacitor placed near the VCC pin is mandatory for DS1100M-350+ stable operation.
Is the DS1100M-350+ pin-compatible with other DS1100 variants?
Yes, all DS1100M-xxx+ variants share identical 8-pin µMAX pinout and electrical behavior - only the nominal delay values differ. TAP 1 through TAP 5, IN, VCC, and GND retain consistent assignment across the family. This allows drop-in replacement during design iteration or BOM optimization without layout changes for DS1100M-350+ and other DS1100M-xxx+ parts.
