Product details
Overview
DS1100LU-30/T&R from Maxim Integrated is a 3.3V, 8-pin µMAX-packaged silicon delay line with five equally spaced taps delivering nominal delays of 6ns (TAP 1), 12ns (TAP 2), 18ns (TAP 3), 24ns (TAP 4), and 30ns (TAP 5). It reproduces both leading and trailing edges with equal precision, drives up to 10 × 74LS loads per tap, and operates across -40°C to +85°C. Used in high-speed timing alignment, clock skew correction, and pulse-width adjustment circuits.
For engineers reviewing the DS1100LU-30/T&R datasheet, DS1100LU-30/T&R pinout, DS1100LU-30/T&R application, or DS1100LU-30/T&R equivalent, key selection criteria include tap delay accuracy over temperature/voltage, TTL/CMOS compatibility, low-power CMOS operation, and µMAX footprint suitability for space-constrained PCBs.
Technical Context
The DS1100LU-30/T&R implements an all-silicon delay architecture with fixed, monotonic delay progression across five outputs-no programmability or variable delay control. Each tap's delay tolerance is ±4ns (≤40ns range) over -40°C to +85°C at 3.3V, and edge fidelity is maintained via matched rise/fall time (2.0–2.5ns) and precise 1.5V-level timing measurement points.
It requires no external components, draws ≤10mA active current at 1MHz, and supports vapor-phase and IR reflow soldering. Input pulse width must exceed 20% of TAP 5 delay (≥6ns), and power-up time is 200μs-critical for systems requiring deterministic startup timing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures stable operation within 3.3V system rails; avoids under-voltage lockout or over-stress |
| Nominal Tap Delays | 6/12/18/24/30ns - fixed, equally spaced delays enabling predictable signal alignment without calibration |
| Delay Tolerance | ±4ns (−40°C to +85°C) - guarantees worst-case timing margin for synchronous logic interfacing |
| Output Drive | 8mA sink / −1mA source - sufficient to directly drive 10 × 74LS inputs without buffering |
| Rise/Fall Time | 2.0–2.5ns - preserves signal integrity for >200MHz edge rates in high-speed digital paths |
| Operating Temp | −40°C to +85°C - qualified for industrial-grade embedded timing applications |
| Power-Up Time | 200μs - defines minimum reset-to-valid-output latency after VCC stabilization |
Pinout & Package
DS1100LU-30/T&R is housed in an 8-pin µMAX package (U8+1 outline, 3mm × 3mm, 0.65mm pitch), compatible with standard SMT assembly processes including lead-free reflow (260°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input; accepts TTL/CMOS-compatible signals (VIH ≥ 2.0V, VIL ≤ 0.8V) |
| 2 | TAP 2 | Second delay output; delivers input signal delayed by 12ns with matched edge fidelity |
| 3 | TAP 4 | Fourth delay output; provides 24ns delay; electrically identical to other taps for load sharing |
| 4 | GND | Digital ground reference; must be low-impedance connection to minimize timing jitter |
| 5 | TAP 5 | Fifth (longest) delay output; 30ns delay; used for maximum skew compensation or pulse extension |
| 6 | TAP 3 | Third delay output; 18ns delay; central tap for symmetric delay interpolation |
| 7 | TAP 1 | First delay output; 6ns delay; lowest-latency tap for minimal skew correction |
| 8 | VCC | +3.3V supply; requires local 0.1μF ceramic decoupling adjacent to pin for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay path | Eliminates hybrid or RC-based drift; ensures ppm-level stability and long-term reliability vs. temperature/voltage |
| Equal tap spacing | Enables linear interpolation between taps and simplifies timing margin analysis in multi-stage logic |
| Leading/trailing edge matching | Preserves pulse width integrity-critical for clock duty-cycle-sensitive circuits and data eye alignment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-30/T&R | Same delay values and electrical specs, but in 8-pin SO (150-mil) package instead of µMAX | Requires larger PCB area; better thermal dissipation but incompatible with ultra-dense layouts | Select when board space permits and SO packaging aligns with existing assembly process |
| ON Semiconductor MC100EP195DG | Differential ECL output, 3.3V supply, 5-tap, but with ±10% delay tolerance (vs. ±4ns absolute for DS1100LU-30/T&R) | Designed for RF/mixed-signal timing; not TTL/CMOS compatible; requires termination and biasing | Select only for ECL environments where differential signaling and higher speed (>1GHz) justify added complexity |
Compared with DS1100LZ-30/T&R and MC100EP195DG, DS1100LU-30/T&R uniquely combines µMAX footprint efficiency, absolute nanosecond delay accuracy, and direct TTL/CMOS interoperability-making it optimal for cost-sensitive, space-constrained industrial digital systems.

FAQ
What is the exact delay value for each tap of the DS1100LU-30/T&R?
The DS1100LU-30/T&R provides five fixed, equally spaced delays: TAP 1 = 6ns, TAP 2 = 12ns, TAP 3 = 18ns, TAP 4 = 24ns, and TAP 5 = 30ns-measured at the 1.5V threshold for both rising and falling edges under VCC = 3.3V and TA = +25°C. These values are guaranteed across the full industrial temperature range with ±4ns tolerance for all taps.
Does the DS1100LU-30/T&R require external components for operation?
No, the DS1100LU-30/T&R operates as a standalone device with no external resistors, capacitors, or clocks required. A single 0.1μF ceramic decoupling capacitor placed near the VCC pin is recommended for noise suppression, but no timing-setting components are needed-the delays are factory-trimmed and silicon-defined.
Can the DS1100LU-30/T&R drive standard TTL loads directly?
Yes, the DS1100LU-30/T&R can drive up to 10 × 74LS loads per tap, confirmed by its IOL = 8mA and IOH = −1mA specifications at VCC = 3.0V. Its TTL-/CMOS-compatible input thresholds (VIH ≥ 2.0V, VIL ≤ 0.8V) and output voltage levels ensure seamless interoperation with legacy and modern logic families without level shifters.
Is the DS1100LU-30/T&R RoHS-compliant and lead(Pb)-free?
Yes, the DS1100LU-30/T&R is RoHS-compliant and lead(Pb)-free, indicated by the "+" suffix in its full ordering code (e.g., DS1100LU-30+/T&R). It supports lead-free reflow soldering up to +260°C and meets JEDEC J-STD-020 moisture sensitivity level 1 standards.
How does temperature affect the delay accuracy of the DS1100LU-30/T&R?
Over −40°C to +85°C, the DS1100LU-30/T&R exhibits a worst-case delay variation of ±4ns for all taps (per AC Electrical Characteristics table). All taps track unidirectionally-e.g., if TAP 1 slows, all others slow proportionally-ensuring consistent relative spacing. This behavior is specified and tested at 3.0V–3.6V supply and eliminates differential skew concerns in multi-tap usage.
