Product details
Overview
DS1100LU-30+T from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 6ns (TAP 1), 12ns (TAP 2), 18ns (TAP 3), 24ns (TAP 4), and 30ns (TAP 5), operating over -40°C to +85°C in an 8-pin µMAX package. It reproduces both leading and trailing edges with equal precision and drives up to 10 LS-TTL loads per tap, used in high-speed timing alignment and signal skew correction.
For engineers reviewing the DS1100LU-30+T datasheet, DS1100LU-30+T pinout, DS1100LU-30+T application, or DS1100LU-30+T equivalent, key selection criteria include tap delay accuracy (±4ns over full temperature range for ≤40ns delays), 3.3V CMOS/TTL compatibility, low-power operation (10mA typical ICC), and µMAX footprint constraints for space-constrained PCBs.
Technical Context
The DS1100LU-30+T implements a monolithic all-silicon delay architecture with five fixed, equally spaced output taps referenced to a single input. Each tap delivers identical edge fidelity-both tPLH and tPHL are specified with matched tolerance-and delay variation is unidirectional across temperature and supply voltage.
It operates strictly as a passive timing element: no internal clock, no configuration interface, and no programmability. Delay values are factory-trimmed and immutable; the "-30" suffix explicitly denotes the TAP 5 delay, with all other taps scaled proportionally (6/12/18/24/30ns) per Table 1 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures stable operation in 3.3V systems with ±10% rail tolerance |
| TAP 5 Delay | 30ns nominal - defines maximum fixed latency path for timing-critical signal alignment |
| Delay Tolerance (≤40ns) | ±4ns over -40°C to +85°C - guarantees deterministic skew control without recalibration |
| Output Drive | 8mA sink / -1mA source - supports direct interfacing to 74LS logic without external buffers |
| Input Capacitance | 5–10pF - minimizes loading on high-speed source drivers and preserves signal integrity |
| Power-Up Time | 200μs - enables immediate use after power stabilization, no initialization sequence required |
| Operating Temp | -40°C to +85°C - qualified for industrial-grade embedded and communications equipment |
Pinout & Package
DS1100LU-30+T is housed in an 8-pin µMAX package (U8+1 outline, 3mm × 3mm body, 0.65mm pitch), compatible with vapor-phase and IR reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended TTL/CMOS-compatible input; accepts 3.3V logic with VIH ≥ 2.0V, VIL ≤ 0.8V |
| 2 | TAP 2 | Second fixed-delay output (12ns); electrically identical to other taps, capable of driving 10 LS loads |
| 3 | TAP 4 | Fourth fixed-delay output (24ns); same rise/fall time (2.0–2.5ns) and delay tolerance as TAP 2 |
| 4 | GND | Analog/digital ground reference; requires low-impedance connection to minimize delay jitter |
| 5 | TAP 5 | Fifth and longest-delay output (30ns); matches TAP 1–4 in edge accuracy and load drive capability |
| 6 | TAP 3 | Third fixed-delay output (18ns); delay tracks unidirectionally with TAP 1–5 under voltage/temperature change |
| 7 | TAP 1 | First fixed-delay output (6ns); shortest latency tap, used for fine-grained timing adjustment |
| 8 | VCC | +3.3V supply; bypassing with 0.1μF ceramic capacitor at pin is mandatory for stable delay performance |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates hybrid packaging drift and aging effects-delivers long-term delay stability vs. ceramic delay lines |
| Equal-edge precision | Identical tPLH and tPHL tolerances ensure zero duty-cycle distortion across all five taps |
| Unidirectional delay tracking | All taps slow or speed together under temp/voltage change-preserves inter-tap spacing integrity |
| µMAX footprint | 3mm × 3mm body saves >60% board area vs. SO-8, critical for compact timing modules and FPGA I/O banks |
| Lead(Pb)-free/RoHS | +T suffix confirms compliance with EU RoHS Directive 2011/65/EU and JEDEC J-STD-020 reflow profiles |
Applications
| High-Speed Logic Skew Correction | FPGA I/O Timing Alignment |
|---|---|
Use Scenario: Compensating for trace-length mismatch between parallel data lines in LVDS or TTL bus interfaces. IC Role / Device Role / Timing Role: Fixed-latency signal replicator providing calibrated delays to realign setup/hold windows at receiver inputs. Use Value: Enables deterministic timing closure without FPGA logic resource overhead or PLL-based dynamic deskew. | Use Scenario: Matching clock-to-out delays across multiple FPGA I/O banks driving synchronous memory or ADC interfaces. IC Role / Device Role / Timing Role: Tap-selectable delay element inserted in clock or strobe paths to equalize propagation to distributed receivers. Use Value: Achieves sub-nanosecond inter-channel skew control using factory-trimmed silicon delays, not calibration-dependent DLLs. |
| Digital Test Equipment Signal Staging | Industrial PLC Input Synchronization |
Use Scenario: Generating precisely offset trigger pulses for multi-channel oscilloscope or logic analyzer acquisition. IC Role / Device Role / Timing Role: Deterministic multi-output delay generator producing five synchronized but staggered logic edges from one input. Use Value: Replaces discrete RC networks or programmable logic with repeatable, temperature-stable delay steps (6/12/18/24/30ns). | Use Scenario: Aligning asynchronous sensor inputs (e.g., limit switches, encoder Z-signals) before sampling by a deterministic controller cycle. IC Role / Device Role / Timing Role: Input conditioning block that introduces known, bounded latency to eliminate metastability risk in safety-critical sampling. Use Value: Guarantees worst-case input-to-sampling delay ≤30ns with ±4ns tolerance-enables certified response-time budgets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-tap delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-30+ | Same delay values and electrical specs, but in 8-pin SO (150-mil) package - larger footprint (4.9mm × 6.0mm) | Preferred where SO-8 hand-soldering, legacy footprint reuse, or higher thermal mass is required | Select DS1100LZ-30+ when board layout allows SO-8 and µMAX assembly capability is unavailable |
| ON Semiconductor MC100EP195MNR4G | 5-tap ECL delay line with 3.3V PECL outputs; ±1.5ps jitter, but requires negative supply (-3.3V) and level-shifting for TTL/CMOS systems | Suitable only in high-speed ECL environments; incompatible with direct 3.3V CMOS/TTL interfacing | Choose MC100EP195MNR4G only for ultra-low-jitter PECL timing chains-not a drop-in replacement for DS1100LU-30+T |
Compared with DS1100LZ-30+, the DS1100LU-30+T saves PCB area and suits high-density layouts, while the MC100EP195MNR4G offers superior jitter performance but demands full ECL infrastructure-neither is pin-compatible, and both require distinct layout and power design decisions.

FAQ
What is the exact delay value for each tap in DS1100LU-30+T?
The DS1100LU-30+T provides five fixed delays: TAP 1 = 6ns, TAP 2 = 12ns, TAP 3 = 18ns, TAP 4 = 24ns, and TAP 5 = 30ns, all nominal at +25°C and VCC = 3.3V. These values scale linearly and track unidirectionally with temperature and supply voltage per the datasheet's delay tolerance specifications.
Does DS1100LU-30+T require external configuration or programming?
No, the DS1100LU-30+T is a fully passive, factory-trimmed silicon delay line with no registers, clocks, or control pins. All five tap delays are hardwired and immutable-no firmware, I²C, or SPI interface exists. The DS1100LU-30+T functions immediately upon power-up with no initialization sequence.
Can DS1100LU-30+T drive standard TTL loads directly?
Yes, each tap of the DS1100LU-30+T can drive up to 10 LS-TTL loads (IOL = 8mA, IOH = -1mA), meeting standard TTL voltage thresholds (VIH ≥ 2.0V, VIL ≤ 0.8V) at 3.3V supply. No level-shifting or buffer ICs are needed for direct interfacing with 74LS or 74F families.
What is the recommended power supply decoupling for DS1100LU-30+T?
A 0.1μF ceramic capacitor must be placed as close as possible to the VCC (pin 8) and GND (pin 4) pins of the DS1100LU-30+T. This minimizes supply noise-induced delay jitter and ensures stable operation across the full -40°C to +85°C range, as validated in Maxim's test conditions.
Is DS1100LU-30+T RoHS-compliant and lead(Pb)-free?
Yes, the "+T" suffix in DS1100LU-30+T explicitly denotes a lead(Pb)-free, RoHS-compliant µMAX package, qualified per JEDEC J-STD-020 for lead-free reflow (peak 260°C). The device meets EU Directive 2011/65/EU and carries full material declarations traceable through Maxim's supply chain.
