Product details
Overview
DS1100LU-45 from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 9ns (TAP 1), 18ns (TAP 2), 27ns (TAP 3), 36ns (TAP 4), and 45ns (TAP 5), operating over -40°C to +85°C, driving up to 10 LS-TTL loads per tap, and housed in an 8-pin µMAX package.
For engineers reviewing the DS1100LU-45 datasheet, DS1100LU-45 pinout, DS1100LU-45 application, or DS1100LU-45 equivalent, this device serves as a precision, edge-aligned timing element for digital signal alignment, clock deskewing, and pulse-width adjustment in high-reliability industrial and communications systems.
Technical Context
The DS1100LU-45 implements a monolithic all-silicon delay architecture with five fixed, equally spaced output taps-each reproducing both leading and trailing edges with ±4ns tolerance over full temperature and voltage range. It requires no external components and operates with TTL-/CMOS-compatible input thresholds (VIH ≥ 2.0V, VIL ≤ 0.8V) at 3.3V supply.
Delay accuracy is specified as ±4% for delays >40ns and ±4ns for delays ≤40ns across -40°C to +85°C; power-up time is 200μs, and output rise/fall times are 2.0–2.5ns. Input capacitance is 5–10pF, and active current draw is 10mA at 1MHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-45 | Same electrical specs and delay values, but in 8-pin SO (150-mil) package instead of µMAX | Requires larger PCB area; better suited for prototyping or manual assembly | Select when board space permits and SO packaging simplifies sourcing or rework |
| ON Semiconductor MC100EP195DG | 5-tap ECL delay line with 3.3V PECL outputs; ±15ps jitter; higher speed but requires termination and negative supply | Targeted at RF and high-frequency test equipment; not drop-in compatible due to interface and supply differences | Select only when sub-100ps jitter and >1GHz bandwidth are required, and system supports PECL infrastructure |
Compared with DS1100LU-45, DS1100LZ-45 offers identical timing performance in a larger SO package, while MC100EP195DG delivers superior jitter performance but demands PECL biasing and careful termination-making DS1100LU-45 optimal for cost-sensitive, space-constrained 3.3V CMOS/TTL systems.

FAQ
What is the operating voltage range for DS1100LU-45?
The DS1100LU-45 operates from 3.0V to 3.6V, optimized for 3.3V logic systems. Operation outside this range may cause timing inaccuracy or damage. The device draws 10mA typical active current at 1MHz and maintains full delay specification compliance across the entire supply range. DS1100LU-45 does not support 5V operation.
How accurate are the delay values of DS1100LU-45 across temperature?
DS1100LU-45 guarantees ±4ns delay tolerance for TAP 1 (9ns) through TAP 4 (36ns), and ±4% for TAP 5 (45ns), over -40°C to +85°C. All taps track unidirectionally with temperature-e.g., if TAP 1 slows, all others slow proportionally-ensuring inter-tap spacing remains stable. DS1100LU-45 achieves this via monolithic silicon delay line design, not discrete components.
Can DS1100LU-45 drive standard TTL loads directly?
Yes, DS1100LU-45 can drive up to 10 LS-TTL loads per tap, with IOL = 8mA and IOH = -1mA at VCC = 3.0V. Its TTL-/CMOS-compatible input thresholds (VIH ≥ 2.0V, VIL ≤ 0.8V) allow direct connection to legacy 74LS outputs. DS1100LU-45 does not require external buffers for typical logic interfacing.
What is the package type and footprint of DS1100LU-45?
DS1100LU-45 uses the 8-pin µMAX package (outline U8+1, land pattern 90-0092), measuring 3mm × 3mm with 0.5mm pitch and an exposed thermal pad. It is RoHS-compliant (lead-free) and compatible with standard vapor-phase and IR reflow processes. DS1100LU-45 is not pin-compatible with SO-8 variants like DS1100LZ-45.
Does DS1100LU-45 support both rising and falling edge delays equally?
Yes, DS1100LU-45 is specifically designed to reproduce both leading and trailing edges with equal precision-critical for pulse-width preservation and glitch filtering. Delay matching between tPLH and tPHL is guaranteed within ±4ns across all taps and operating conditions. This edge symmetry is inherent to its all-silicon architecture and verified in the DS1100LU-45 datasheet timing diagrams.
