Product details
Overview
DS1100LU-40 from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 8ns (TAP 1), 16ns (TAP 2), 24ns (TAP 3), 32ns (TAP 4), and 40ns (TAP 5), operating over -40°C to +85°C, delivering precise edge-aligned timing for high-speed digital synchronization in test equipment and logic interface circuits.
For engineers reviewing the DS1100LU-40 datasheet, DS1100LU-40 pinout, DS1100LU-40 application, or DS1100LU-40 equivalent, key selection criteria include tap delay accuracy (±4ns over full temperature range), TTL/CMOS compatibility, 3.3V supply operation, and µMAX-8 package footprint constraints.
Technical Context
The DS1100LU-40 implements an all-silicon delay architecture that reproduces both leading and trailing edges with equal precision at each of five fixed taps. Delay values are stable across voltage (3.0V–3.6V) and temperature (-40°C to +85°C), with unidirectional drift behavior ensuring monotonic variation across all taps under changing conditions.
Each output drives up to 10 74LS loads with rise/fall times ≤2.5ns and supports input pulse widths ≥20% of TAP 5 delay. Power-up time is 200μs, and active current draw is 10mA at 1MHz with VCC = max.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures compatibility with 3.3V logic systems and robust operation across industrial voltage tolerances |
| TAP 5 Delay | 40ns nominal - defines maximum fixed propagation latency for timing alignment in synchronous logic paths |
| Delay Tolerance | ±4ns (≤40ns taps, -40°C to +85°C) - guarantees deterministic edge placement without recalibration in embedded control loops |
| Output Drive | 8mA sink / -1mA source - sufficient to directly interface with 74LS-family inputs without external buffering |
| Input Capacitance | 5–10pF - minimizes loading on upstream drivers and preserves signal integrity in high-frequency clock distribution |
| Package | 8-pin µMAX (U8+1) - 3mm × 3mm footprint enables dense PCB layout in space-constrained instrumentation designs |
Pinout & Package
The DS1100LU-40 is housed in an 8-pin µMAX package (outline no. 21-0036), measuring 3.0mm × 3.0mm × 0.8mm with exposed thermal pad, compatible with vapor-phase and IR reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input accepting TTL/CMOS-compatible signals; referenced to GND |
| 2 | TAP 2 | Second delay output (16ns); delivers inverted or non-inverted copy of IN depending on internal topology |
| 3 | TAP 4 | Fourth delay output (32ns); electrically identical to other taps in drive strength and timing spec |
| 4 | GND | Analog/digital ground reference; must be low-impedance connection for stable delay performance |
| 5 | TAP 5 | Fifth delay output (40ns); longest fixed delay path; used for coarse timing alignment |
| 6 | TAP 3 | Third delay output (24ns); midpoint tap enabling symmetric delay interpolation in sampling circuits |
| 7 | TAP 1 | First delay output (8ns); shortest fixed delay; supports fine-grained skew correction |
| 8 | VCC | +3.3V supply input; requires local 0.1μF ceramic decoupling adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay line | Eliminates hybrid packaging reliability risks and enables full CMOS process control for consistent delay matching across taps |
| Equal-edge precision | Simultaneous leading- and trailing-edge delay accuracy ensures clean pulse-width preservation in gated clock paths |
| Five fixed taps | Provides discrete, factory-trimmed delay points without external components or configuration overhead |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-40 | Same electrical specs and delay values, but in 8-pin SO (150-mil) package instead of µMAX | Requires larger PCB footprint and different land pattern; suitable for through-hole prototyping or legacy SO layouts | Select DS1100LZ-40 only when µMAX assembly capability is unavailable or SO-8 is mandated by existing design rules |
| ON Semiconductor MC100EP195MNR4G | 5-tap ECL delay line with 3.3V operation; ±15% delay tolerance vs. ±10% for DS1100LU-40 at 40ns; higher power consumption | Designed for RF and high-frequency serial link timing; less suited for low-power industrial logic interfaces | Choose MC100EP195MNR4G only when ECL-level signaling or faster edge rates (<1ns) are required |
Compared with DS1100LZ-40 and MC100EP195MNR4G, the DS1100LU-40 offers the smallest footprint and tightest delay tolerance (±4ns) for 3.3V CMOS/TTL systems, making it optimal for space-constrained, precision-timing applications where µMAX assembly is supported.

FAQ
What is the nominal delay value for each tap of the DS1100LU-40?
The DS1100LU-40 provides five equally spaced nominal delays: TAP 1 = 8ns, TAP 2 = 16ns, TAP 3 = 24ns, TAP 4 = 32ns, and TAP 5 = 40ns. These values are factory-characterized at +25°C and VCC = 3.3V, with guaranteed tolerance of ±4ns over the full -40°C to +85°C operating range. Each tap reproduces both leading and trailing edges with equal precision, as confirmed in the DS1100L datasheet revision 7/15.
Does the DS1100LU-40 support 5V logic inputs?
No, the DS1100LU-40 is a 3.3V-only device specified for VCC = 3.0V to 3.6V. Its input thresholds are VIH ≥ 2.0V and VIL ≤ 0.8V, making it compatible with 3.3V TTL and CMOS logic families but not directly interoperable with 5V systems without level translation. Applying 5V to any pin exceeds the absolute maximum rating of +6.0V relative to GND only as a stress limit-not for functional operation-and may compromise reliability.
Can the DS1100LU-40 drive standard 74LS logic loads directly?
Yes, the DS1100LU-40 is rated to drive up to 10 74LS loads per tap, with IOL = 8mA and IOH = -1mA at VCC = min. This capability is verified under DC electrical test conditions in the datasheet and applies across the full industrial temperature range. No external buffer is required when interfacing with legacy 74LS-series inputs, simplifying system-level timing circuit design.
Is the DS1100LU-40 RoHS-compliant?
Yes, the DS1100LU-40 is offered in a lead(Pb)-free/RoHS-compliant package, indicated by the "+" suffix in ordering codes such as DS1100LU-40+. The µMAX package (U8+1) meets JEDEC J-STD-020 reflow standards, with peak soldering temperature of +260°C for lead-free processes. RoHS compliance is documented in Maxim's official package information and ordering guide.
How does temperature affect delay matching between taps in the DS1100LU-40?
Delay matching between taps in the DS1100LU-40 remains highly consistent because all taps exhibit unidirectional drift-i.e., if one tap slows down due to temperature increase, all others slow down proportionally. This behavior, explicitly noted in datasheet Note 3, ensures monotonic variation and preserves relative spacing (e.g., TAP 2 – TAP 1 remains ~8ns). Full-range tolerance is ±4ns for all taps at -40°C to +85°C, guaranteeing stable inter-tap relationships in thermally varying environments.
