Product details
Overview
DS1100U-30+ from Maxim Integrated is a 5-tap silicon delay line in an 8-pin µMAX package, delivering precisely spaced 6ns, 12ns, 18ns, 24ns, and 30ns delays at 5V supply. It reproduces both leading and trailing edges with ±4ns tolerance over -40°C to +85°C, drives up to 10 LS-TTL loads per tap, and serves as a low-power, RoHS-compliant replacement for hybrid delay lines in timing-critical digital systems.
For engineers reviewing the DS1100U-30+ datasheet, DS1100U-30+ pinout, DS1100U-30+ application, or DS1100U-30+ equivalent, key selection factors include tap delay precision across temperature, TTL/CMOS compatibility, 5V operation, µMAX footprint constraints, and industrial-grade reliability without hybrid construction.
Technical Context
The DS1100U-30+ implements a monolithic all-silicon delay architecture with five fixed, equally spaced output taps derived from a single input signal. Each tap delivers deterministic propagation delay with matched edge fidelity-tPLH and tPHL both specified within ±4ns over full industrial temperature range.
It operates exclusively at 5V (4.75V–5.25V), draws 30–50mA active current, and maintains stable delay accuracy despite supply variation or temperature drift due to unidirectional delay shift behavior across all taps-ensuring consistent relative timing relationships in clock distribution or pulse shaping circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Tap Delays | 6ns / 12ns / 18ns / 24ns / 30ns - fixed, equally spaced delays referenced to input edge at 1.5V threshold |
| Delay Tolerance | ±4ns (≤40ns delays) over -40°C to +85°C - ensures predictable setup/hold margins in synchronous logic |
| Supply Voltage | 4.75V to 5.25V - compatible with standard 5V logic rails and decoupling schemes |
| Output Drive | 12mA sink / -1mA source - sufficient for direct interface to 10× 74LS loads without buffering |
| Input Capacitance | 5–10pF - minimizes loading on preceding stage and preserves signal integrity at high edge rates |
| Operating Temperature | -40°C to +85°C - qualified for industrial control, test equipment, and embedded timing applications |
| Power-Up Time | 200μs - defines minimum reset-to-valid-output latency after VCC stabilization |
Pinout & Package
DS1100U-30+ uses an 8-pin µMAX package (U8+1 outline, 3mm × 3mm body, 0.65mm pitch), pin-compatible with industry-standard SO-8 but with reduced PCB area and thermal profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Signal Input | Accepts TTL/CMOS-compatible 5V logic input; 5–10pF capacitance limits high-frequency loading |
| 2 (TAP 1) | First Delay Output | Delivers 6ns-delayed replica of input with matched tPLH/tPHL; drives up to 10 LS-TTL loads |
| 3 (TAP 2) | Second Delay Output | Delivers 12ns-delayed replica; delay relationship to TAP 1 is fixed and temperature-invariant |
| 4 (TAP 3) | Third Delay Output | Delivers 18ns-delayed replica; all taps shift unidirectionally with voltage/temperature changes |
| 5 (TAP 4) | Fourth Delay Output | Delivers 24ns-delayed replica; enables multi-stage pipeline or staggered sampling without external logic |
| 6 (TAP 5) | Fifth Delay Output | Delivers 30ns-delayed replica; final tap used for maximum delay path or reference alignment |
| 7 (GND) | Ground Reference | Common return for all I/O and internal circuitry; requires low-impedance connection to minimize noise coupling |
| 8 (VCC) | Power Supply | +5V supply pin; requires local 0.1μF ceramic decoupling adjacent to pin for stable AC performance |

IC Role / Device Role / Timing Role: Supplies multiple phase-aligned sampling points to identify optimal data capture timing. Use Value: Allows real-time selection of best-performing tap based on BER feedback-no FPGA reconfiguration required. | Use Scenario: Creating cascaded trigger conditions across multiple logic analyzer channels with sub-nanosecond relative timing control. IC Role / Device Role / Timing Role: Generates hierarchical trigger enable signals with fixed temporal offsets for state-machine debugging. Use Value: Reduces false triggers by enforcing strict sequence validity-e.g., "Event A must occur 12ns before Event B" with hardware enforcement. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1000Z-30+ | Hybrid construction; larger SO-8 footprint; ±5% delay tolerance above 40ns; higher power consumption | Legacy drop-in where board space and thermal budget allow; not recommended for new designs requiring long-term supply stability | Select DS1100U-30+ for superior reliability, smaller size, and tighter delay tolerance in new industrial designs |
| SN74LVC1G123DCKR | Retriggerable monostable multivibrator; programmable one-shot delay; no fixed multi-tap outputs | Suitable for single-event timing or pulse stretching, but cannot replicate five simultaneous, equally spaced delays | Choose DS1100U-30+ when deterministic multi-point delay replication-not variable one-shot timing-is required |
Compared with DS1000Z-30+, DS1100U-30+ offers tighter delay tolerance, smaller µMAX footprint, and all-silicon reliability; compared with SN74LVC1G123DCKR, it provides five simultaneous, fixed, and equally spaced delays-enabling parallel timing paths impossible with single-output monostables.

FAQ
What is the nominal delay value for each tap of the DS1100U-30+?
The DS1100U-30+ provides five equally spaced delays: TAP 1 = 6ns, TAP 2 = 12ns, TAP 3 = 18ns, TAP 4 = 24ns, and TAP 5 = 30ns-each measured from the 1.5V point of the input edge to the corresponding 1.5V point on the output edge. These values are specified at +25°C and 5V, with tolerances scaling with temperature and voltage per the datasheet's AC Electrical Characteristics table.
Is the DS1100U-30+ pin-compatible with other DS1100 variants?
Yes-the DS1100U-30+ shares the same 8-pin µMAX pinout as all DS1100U-x variants (e.g., DS1100U-20+, DS1100U-50+). Pin assignments for IN, TAP 1–5, VCC, and GND are identical across the U-series, enabling layout reuse when changing delay values within the same package family.
Does the DS1100U-30+ support both rising and falling edge delay accuracy?
Yes-the DS1100U-30+ is explicitly characterized for both tPLH (rising edge) and tPHL (falling edge) delays, with equal ±4ns tolerance over -40°C to +85°C. This dual-edge fidelity ensures accurate pulse-width reproduction and makes DS1100U-30+ suitable for applications like clock deskewing and strobe generation where duty cycle integrity matters.
Can the DS1100U-30+ drive standard TTL loads directly?
Yes-the DS1100U-30+ can drive up to 10 LS-TTL loads per tap, verified by its IOL = 12mA and IOH = -1mA specifications at VCC = 4.75V. Its TTL/CMOS-compatible input thresholds and output voltage levels ensure interoperability with 74LS, 74ALS, and modern 74HC families without external level-shifting circuitry.
What is the significance of the '+' suffix in DS1100U-30+?
The '+' suffix in DS1100U-30+ indicates a lead(Pb)-free, RoHS-compliant µMAX package (U8+1 outline). It reflects full compliance with EU RoHS Directive 2011/65/EU and has identical electrical and thermal performance to non-RoHS versions-no derating or design changes are required when substituting DS1100U-30+ into existing layouts.
