Product details
Overview
DS1100LZ-40+T 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, TTL/CMOS-compatible, and packaged in an 8-pin SO (150 mils) surface-mount package for high-density timing control in digital signal alignment applications.
For engineers reviewing the DS1100LZ-40+T datasheet, DS1100LZ-40+T pinout, DS1100LZ-40+T application, or DS1100LZ-40+T equivalent, this device delivers precise, temperature-stable edge-aligned delays across five fixed taps-critical for clock deskew, pulse width adjustment, signal synchronization, and logic timing correction in industrial and communications systems.
Technical Context
The DS1100LZ-40+T implements a monolithic all-silicon delay architecture that reproduces both leading and trailing edges with equal precision at each tap, eliminating phase skew between rising/falling transitions. Its delay tolerance is ±4ns over -40°C to +85°C for delays ≤40ns, and it maintains stable propagation characteristics across 3.0V–3.6V supply range.
Each output drives up to 10 74LS loads, supports 2.0–2.5ns rise/fall times, and features low-power CMOS operation with active current ≤10mA at 1MHz. Input pulse width must be ≥20% of TAP 5 delay (≥8ns), and power-up time is 200μs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures compatibility with 3.3V logic families and robust noise margin in mixed-signal environments |
| Nominal Tap Delays | 8ns / 16ns / 24ns / 32ns / 40ns - fixed, equally spaced delays enabling deterministic signal alignment without programmability overhead |
| Delay Tolerance | ±4ns (−40°C to +85°C) - guarantees consistent timing margins across industrial temperature range |
| Input Compatibility | TTL-/CMOS-compatible - accepts standard 3.3V logic thresholds (VIH ≥ 2.0V, VIL ≤ 0.8V) |
| Output Drive | 8mA sink / −1mA source - sufficient to directly drive 10× 74LS inputs without external buffering |
| Package | 8-pin SO (150 mils) - industry-standard footprint enabling drop-in replacement and automated assembly |
Pinout & Package
DS1100LZ-40+T is housed in an 8-pin Small Outline (SO) package, 150 mils wide, RoHS-compliant (lead-free), vapor-phase and IR solderable, with 1.27mm pitch and standard JEDEC MO-153 outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Logic input signal source - accepts TTL/CMOS-level pulses; defines delay origin for all taps |
| 2 | TAP 2 | Second delayed output - provides 16ns fixed delay; electrically identical to other taps for load sharing |
| 3 | TAP 4 | Fourth delayed output - provides 32ns fixed delay; usable for intermediate timing points in multi-stage alignment |
| 4 | GND | Ground reference - common return path for supply and signal integrity; requires low-inductance PCB connection |
| 5 | TAP 5 | Fifth delayed output - provides 40ns maximum delay; used for full-range timing calibration or final stage synchronization |
| 6 | TAP 3 | Third delayed output - provides 24ns fixed delay; central tap for symmetric delay interpolation |
| 7 | TAP 1 | First delayed output - provides 8ns minimum delay; enables fine-grained timing adjustments near input edge |
| 8 | VCC | +3.3V supply - powers internal delay circuitry; requires local 0.1μF ceramic decoupling per datasheet layout guidance |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates hybrid or ceramic delay line reliability risks and enables full CMOS process integration with predictable aging behavior |
| Equal leading/trailing edge accuracy | Ensures symmetrical pulse distortion control - critical for duty-cycle preservation in clock recovery and data retiming |
| Five equally spaced taps | Provides deterministic, non-overlapping delay steps for multi-point signal sampling or staggered enable generation |
| Stable delay tolerance over temp/voltage | ±4ns max deviation across −40°C to +85°C and 3.0V–3.6V - reduces need for system-level calibration |
| Low-power CMOS operation | ≤10mA ICC at 1MHz - minimizes thermal impact and simplifies power delivery in dense timing subsystems |

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 delay values and SO package, but supplied in cut tape (not tape-and-reel); no functional difference | No change in use case - suitable for prototyping or low-volume production where reel packaging is unnecessary | Select DS1100LZ-40+ when manual placement or small-batch assembly is preferred |
| DS1100LU-40+T | Identical electrical specs and delay values, but in 8-pin µMAX (U8+1) package - 3mm × 3mm vs. SO's 4.9mm × 6mm | Used where PCB area is constrained; requires different land pattern and reflow profile due to smaller thermal mass | Choose DS1100LU-40+T only when board space savings justify redesigning layout and qualifying new assembly process |
Compared with DS1100LZ-40+, DS1100LZ-40+T offers tape-and-reel packaging for automated SMT lines, while DS1100LU-40+T trades package size for identical timing performance - making DS1100LZ-40+T optimal for volume industrial manufacturing requiring consistent feeder compatibility and traceable lot control.

FAQ
What is the operating temperature range for DS1100LZ-40+T?
The DS1100LZ-40+T is fully specified and guaranteed over the industrial temperature range of −40°C to +85°C. All electrical parameters-including delay tolerance (±4ns), supply current, and input/output thresholds-are tested and validated across this full range, ensuring reliable operation in harsh environments such as factory floor controllers and outdoor telecom equipment.
Does DS1100LZ-40+T support both rising and falling edge delays?
Yes, DS1100LZ-40+T reproduces both leading and trailing edges with equal precision-each tap delivers identical delay for tPLH (rising) and tPHL (falling) transitions. This symmetry preserves pulse width integrity and eliminates duty-cycle distortion, making DS1100LZ-40+T suitable for bidirectional timing applications like clock inversion chains and dual-edge triggered circuits.
Can DS1100LZ-40+T drive standard TTL loads directly?
Yes, DS1100LZ-40+T can drive up to 10 standard 74LS loads per tap without external buffers. Its IOL = 8mA and IOH = −1mA specifications meet 74LS input current requirements, and its TTL-/CMOS-compatible input thresholds ensure seamless interfacing with legacy and modern logic families alike-no level-shifting required when used with DS1100LZ-40+T.
What is the meaning of the "+T" suffix in DS1100LZ-40+T?
The "+T" suffix in DS1100LZ-40+T indicates RoHS-compliant (lead-free) construction in tape-and-reel packaging. The "+" denotes lead-free/RoHS compliance per EU directive, while "T" specifies packaging format optimized for automated surface-mount assembly lines-distinct from cut-tape ("+") or bulk ("") variants of the same DS1100LZ-40+T device.
How does DS1100LZ-40+T differ from the original DS1100?
DS1100LZ-40+T is the 3.3V version of the DS1100, characterized for 3.0V–3.6V operation versus the original's 5V supply. It retains identical 5-tap architecture and delay spacing but improves power efficiency, reduces EMI, and enables direct interface with modern low-voltage logic-making DS1100LZ-40+T the preferred choice for new 3.3V system designs where DS1100 would require level translation.
