Product details
Overview
DS1100LU-200+ from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 40ns, 80ns, 120ns, 160ns, and 200ns across TAP1–TAP5. It operates from 3.0V to 3.6V over –40°C to +85°C, delivers TTL-/CMOS-compatible outputs, and drives up to 10 × 74LS loads per tap. Used in high-speed timing alignment for test equipment and digital signal synchronization.
For engineers reviewing the DS1100LU-200+ datasheet, DS1100LU-200+ pinout, DS1100LU-200+ application, or DS1100LU-200+ equivalent, key selection criteria include tap delay precision (±4ns at –40°C to +85°C), leading/trailing edge matching, low-power CMOS operation, and µMAX® 8-pin surface-mount packaging for space-constrained PCBs.
Technical Context
The DS1100LU-200+ implements an all-silicon delay architecture with five fixed, equally spaced delay taps referenced to a single input signal. Each tap reproduces both rising and falling edges with matched propagation delay tolerance-critical for skew-sensitive applications like clock deskewing and pulse width stabilization.
Delay accuracy is specified as ±4ns (for ≤40ns taps) or ±13% (for >40ns taps) over full temperature and voltage range, with unidirectional drift behavior: all taps speed up or slow down together under voltage/temperature shifts. Input-to-output timing is measured at the 1.5V logic threshold with 3ns max input rise/fall time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures compatibility with 3.3V logic systems and stable delay performance across rail variation |
| Nominal Tap Delays | 40ns / 80ns / 120ns / 160ns / 200ns - enables precise multi-stage timing alignment without external components |
| Delay Tolerance | ±4ns (TAP1–TAP3), ±13% (TAP4–TAP5) at –40°C to +85°C - defines worst-case skew between stages in industrial environments |
| Output Drive | 8mA sink / –1mA source - supports direct interfacing to 74LS loads without buffering |
| Input Capacitance | 5–10pF - minimizes loading on upstream drivers and preserves signal integrity at high frequencies |
| Power-Up Time | 200μs - guarantees stable output within one microsecond after supply stabilization |
Pinout & Package
DS1100LU-200+ uses the 8-pin µMAX® package (U8+1 outline), measuring 3.0mm × 3.0mm × 0.8mm with exposed pad for thermal enhancement. The package is RoHS-compliant (lead-free) and vapor-phase/IR solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input; accepts TTL-/CMOS-compatible signals with 2.0V VIH min |
| 2 | TAP 2 | Second delay output (80ns); fully buffered, capable of driving 10 × 74LS loads |
| 3 | TAP 4 | Fourth delay output (160ns); matches TAP2 edge fidelity for cascaded timing paths |
| 4 | GND | Digital ground reference; must be connected to low-impedance PCB plane for timing stability |
| 5 | TAP 5 | Fifth delay output (200ns); highest-delay tap with ±13% tolerance over full temperature range |
| 6 | TAP 3 | Third delay output (120ns); center tap used for mid-point sampling or feedback generation |
| 7 | TAP 1 | First delay output (40ns); lowest-latency tap for minimal-skew path insertion |
| 8 | VCC | +3.3V supply; requires local 0.1μF ceramic decoupling adjacent to pin |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1023-200+ (Maxim) | 3-tap, 200ns max delay; SO-8 package; ±5% delay tolerance at full temperature range | Limited to coarse-grained delay steps; lacks TAP2/TAP4 for fine alignment | Select when only three delay points are needed and board space allows larger SO-8 footprint |
| 74LVC1G125-200 (Nexperia) | Single-output, adjustable delay via external RC; no guaranteed edge matching; ±20% tolerance | Requires external components and calibration; unsuitable for multi-tap synchronization | Choose only for cost-sensitive, non-critical timing where programmability outweighs precision |
Compared with DS1100LU-200+, DS1023-200+ offers fewer taps but identical RoHS-compliant SO-8 packaging, while 74LVC1G125-200 trades precision and multi-output capability for bill-of-materials simplicity-neither matches DS1100LU-200+'s 5-tap edge-matched repeatability in industrial timing systems.

FAQ
What is the maximum operating frequency supported by DS1100LU-200+?
The DS1100LU-200+ does not specify a maximum operating frequency but is characterized for input pulse periods down to 1μs (1MHz repetition rate). At higher frequencies, active current (ICC) increases, and delay accuracy degrades due to layout sensitivity and decoupling limitations. For reliable operation, DS1100LU-200+ should be used with input signals having ≥500ns minimum pulse width and proper PCB decoupling.
Does DS1100LU-200+ support both rising and falling edge delays independently?
Yes, DS1100LU-200+ reproduces both leading and trailing edges with equal precision-tPLH and tPHL are matched within ±4ns for TAP1–TAP3 and ±13% for TAP4–TAP5. This edge symmetry ensures pulse width integrity across all five taps, making DS1100LU-200+ suitable for applications requiring duty-cycle preservation.
Can DS1100LU-200+ drive 74ACT loads directly?
No, DS1100LU-200+ is rated for 10 × 74LS loads (8mA sink / –1mA source), while 74ACT loads require higher drive strength (typically ±24mA). Driving 74ACT directly may cause marginal VOH/VOL levels or timing violations. For 74ACT interfacing, DS1100LU-200+ should be paired with a buffer such as SN74LVC244A to maintain signal integrity and timing accuracy.
Is the DS1100LU-200+ pinout compatible with other DS1100L variants in µMAX packaging?
Yes, all DS1100LU-xxx variants share identical 8-pin µMAX pinout and electrical specifications-only nominal delay values differ. DS1100LU-200+ can be substituted with DS1100LU-150+ or DS1100LU-250+ without PCB changes, provided system timing margins accommodate the new delay profile.
What is the significance of the "+" suffix in DS1100LU-200+?
The "+" suffix in DS1100LU-200+ indicates a lead(Pb)-free, RoHS-compliant µMAX package. It confirms compliance with EU Directive 2011/65/EU and has identical electrical and thermal performance to non-RoHS versions. DS1100LU-200+ is qualified for reflow soldering up to +260°C and meets JEDEC J-STD-020 moisture sensitivity level 1.
