Product details
Overview
DS1100U-30 from Maxim Integrated is a 5-tap silicon delay line in an 8-pin µMAX package, delivering precise fixed delays of 6ns, 12ns, 18ns, 24ns, and 30ns across taps 1–5. It operates at 5V, reproduces both leading and trailing edges with ±4ns tolerance over –40°C to +85°C, 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 DS1100U-30 datasheet, DS1100U-30 pinout, DS1100U-30 application, or DS1100U-30 equivalent, key selection criteria include tap delay accuracy over temperature/voltage, TTL/CMOS compatibility, low-power CMOS operation, and µMAX footprint suitability for high-density PCBs requiring stable analog-matched digital delays.
Technical Context
The DS1100U-30 implements an all-silicon delay architecture with five equally spaced, monotonic delay taps-ensuring unidirectional delay variation (e.g., if TAP1 slows, all taps slow proportionally). Delay values are specified at 1.5V switching threshold with 3ns max input rise/fall time and measured using IEEE 488-automated time-interval counters.
It supports full industrial temperature range (–40°C to +85°C) with ±4ns absolute tolerance for ≤40ns delays and ±13% for >40ns delays, referenced to nominal 5V supply. Input pulse width must exceed 20% of TAP5 delay (≥6ns), and power-up time is 200μs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| TAP Delays | 6ns / 12ns / 18ns / 24ns / 30ns - fixed, monotonic, equally spaced delays for sequential signal alignment |
| Supply Voltage | 4.75V to 5.25V - ensures robust operation across standard 5V rail tolerances without regulation |
| Delay Tolerance | ±4ns (≤40ns taps) over –40°C to +85°C - enables deterministic timing in industrial environments |
| Output Drive | 12mA sink / –1mA source - sufficient for direct interface to 10× 74LS loads without buffering |
| Input Capacitance | 5–10pF - minimizes loading on preceding logic stage and preserves signal integrity |
| 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, 0.65mm pitch), compatible with vapor-phase, IR, and wave soldering. Pin 1 is VCC; pins 2–6 alternate TAP outputs; pin 7 is IN; pin 8 is GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply | 5V power input; decoupling capacitor required near pin for noise immunity |
| TAP 1 | First delayed output | Delivers input signal after 6ns; used for shortest-path timing compensation |
| TAP 2 | Second delayed output | Delivers input signal after 12ns; enables intermediate phase alignment |
| TAP 3 | Third delayed output | Delivers input signal after 18ns; central tap for symmetric delay distribution |
| TAP 4 | Fourth delayed output | Delivers input signal after 24ns; supports multi-stage pipeline synchronization |
| TAP 5 | Fifth delayed output | Delivers input signal after 30ns; maximum delay tap for coarse timing control |
| IN | Digital input | Accepts TTL/CMOS-compatible 0V/3V logic; 5–10pF input capacitance limits trace length |
| GND | Ground reference | Common return path for all internal delay elements and output drivers |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates hybrid packaging drift and aging effects-enables 10+ year reliability in embedded systems |
| Leading/trailing-edge accuracy | Equal ±4ns tolerance on rising and falling edges-critical for duty-cycle preservation in clocked logic |
| 5V TTL/CMOS compatibility | Direct interface with legacy and modern logic families without level-shifting circuitry |
| Monotonic delay variation | All taps shift uniformly with temperature/voltage-prevents relative skew inversion in multi-tap use |
| µMAX surface-mount package | 3mm × 3mm footprint saves >60% board area vs. SO-8-ideal for space-constrained instrumentation |
Applications
| Digital Clock Skew Correction | Pulse Width Adjustment |
|---|---|
Use Scenario: Aligning clock edges across multiple ASIC/FPGA inputs to meet setup/hold timing margins. IC Role / Device Role / Timing Role: DS1100U-30 provides calibrated, matched delays per clock domain to eliminate inter-chip skew. Use Value: Achieves sub-nanosecond edge alignment consistency across –40°C to +85°C without calibration firmware. | Use Scenario: Extending narrow trigger pulses from sensors or comparators to meet minimum width requirements of downstream logic. IC Role / Device Role / Timing Role: DS1100U-30 generates parallel delayed versions of input pulse to construct adjustable-width output via OR-gating.

| Logic Glitch Filtering | Test Equipment Signal Delay Calibration |
Use Scenario: Removing sub-10ns metastability-induced glitches on asynchronous control lines before latching. IC Role / Device Role / Timing Role: DS1100U-30 delays both true and complement paths; XOR output cancels spikes shorter than smallest tap delay.

IC Role / Device Role / Timing Role: DS1100U-30 serves as traceable, temperature-stable delay standard for channel-to-channel skew verification. Use Value: Delivers ±4ns absolute accuracy traceable to factory characterization-replaces expensive coaxial delay lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1000-30 | Hybrid construction; ±10ns delay tolerance; higher power consumption; obsolete since 2005 | Limited to commercial temp range (0°C to +70°C); not qualified for industrial reflow | Select DS1100U-30 for improved stability, wider temperature range, and RoHS-compliant µMAX packaging. |
| MAX9600EUA+ | Programmable 8-tap delay IC; SPI-configurable; 1.8V–5.5V supply; 250ps resolution | Requires external controller and firmware; supports dynamic delay adjustment-not fixed-tap replacement | Choose MAX9600EUA+ only when variable delay or fine-grained (sub-ns) control is required; DS1100U-30 remains optimal for static, low-cost, zero-overhead timing. |
Compared with DS1000-30 and MAX9600EUA+, the DS1100U-30 delivers superior thermal stability, smaller footprint, and simpler integration-making it the preferred choice for cost-sensitive, high-reliability fixed-delay applications where programmability is unnecessary.

FAQ
What is the operating temperature range for DS1100U-30?
The DS1100U-30 is rated for continuous operation from –40°C to +85°C. All electrical specifications-including delay tolerance (±4ns for taps ≤40ns), supply current (30–50mA), and output drive capability-are guaranteed across this full industrial temperature range, making DS1100U-30 suitable for harsh-environment applications such as factory automation and outdoor instrumentation.
Does DS1100U-30 support both rising and falling edge delays?
Yes, DS1100U-30 reproduces both leading and trailing edges with equal precision-each tap delivers identical delay for tPLH (rising) and tPHL (falling) transitions. This symmetry ensures duty-cycle fidelity in clock distribution and pulse-shaping applications, and is verified per datasheet Note 1 with ±4ns tolerance at +25°C and across the full –40°C to +85°C range.
What load can each tap of DS1100U-30 drive?
Each tap of DS1100U-30 can directly drive up to 10 LS-TTL loads (i.e., 10 × 74LS inputs), as confirmed in the General Description and DC Electrical Characteristics. This corresponds to a guaranteed low-level output current (IOL) of 12mA and high-level output current (IOH) of –1mA at VCC = 4.75V, enabling robust fanout without external buffers in most digital timing circuits.
Is DS1100U-30 RoHS-compliant and lead(Pb)-free?
Yes, DS1100U-30 is RoHS-compliant and lead(Pb)-free. The "+" suffix in ordering codes (e.g., DS1100U-30+) explicitly denotes compliance, and the µMAX package (U8+1) meets JEDEC J-STD-609A Class 3 moisture sensitivity and Pb-free reflow standards (260°C peak). Standard DS1100U-30 units shipped post-2011 are also RoHS-compliant unless otherwise marked.
How does DS1100U-30 differ from DS1100Z-30?
DS1100U-30 and DS1100Z-30 share identical electrical specifications and delay values (6ns–30ns), but differ only in package: DS1100U-30 uses the 3mm × 3mm µMAX (U8+1) package, while DS1100Z-30 uses the 150-mil SO-8 (S8+4) package. Layout, thermal performance, and board area utilization differ accordingly-DS1100U-30 targets high-density designs; DS1100Z-30 suits legacy SO-8 footprints.
