Product details
Overview
DS1100LU-100+TR from Maxim Integrated is a 3.3V, 5-tap silicon delay line in an 8-pin µMAX package, delivering precisely spaced delays of 20ns, 40ns, 60ns, 80ns, and 100ns. It reproduces both leading and trailing edges with ±4ns tolerance over –40°C to +85°C, drives up to 10 LS-TTL loads per tap, and operates with 3.0V–3.6V supply. It is used in high-speed timing alignment for logic synchronization and pulse shaping in industrial control interfaces.
For engineers reviewing the DS1100LU-100+TR datasheet, DS1100LU-100+TR pinout, DS1100LU-100+TR application, or DS1100LU-100+TR equivalent, key selection criteria include tap delay accuracy across temperature, edge fidelity for dual-edge timing, TTL/CMOS compatibility, and µMAX footprint constraints in space-constrained PCB layouts.
Technical Context
The DS1100LU-100+TR implements a monolithic all-silicon delay architecture-no hybrid or RC-based elements-with five fixed, equally spaced delay taps derived from a single input signal. Each tap replicates the input logic state after its nominal delay, maintaining consistent propagation characteristics for both rising and falling edges.
Delay tolerance is specified as ±4ns (for ≤40ns taps) or ±13% (for >40ns taps) over the full –40°C to +85°C range at 3.0V–3.6V. All taps track unidirectionally with voltage and temperature changes, ensuring monotonic delay variation critical for skew-sensitive timing paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures stable operation in 3.3V logic systems with ±10% rail tolerance |
| Nominal Tap Delays | 20ns / 40ns / 60ns / 80ns / 100ns - fixed, equally spaced delays enabling precise multi-point timing alignment |
| Delay Tolerance | ±4ns (TAP1–TAP3), ±13% (TAP4–TAP5) over –40°C to +85°C - defines worst-case skew between taps in thermal cycling |
| Output Drive Strength | 8mA sink / –1mA source - supports direct interface to 10× 74LS loads without buffering |
| Input Compatibility | TTL- and CMOS-compatible thresholds (VIH ≥ 2.0V, VIL ≤ 0.8V) - enables seamless integration with mixed-logic families |
| Power Consumption | 10mA typical ICC at 1MHz - low static current suitable for always-on timing functions in power-sensitive designs |
Pinout & Package
DS1100LU-100+TR is housed in an 8-pin µMAX package (U8+1 outline, 3mm × 3mm, 0.65mm pitch), compatible with vapor-phase and IR reflow soldering per RoHS-compliant lead-free process (+ suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Signal Input | Accepts TTL/CMOS logic pulses; triggers all five delay taps simultaneously |
| 2 TAP 2 | Delayed Output | Delivers input signal delayed by 40ns; electrically identical to other taps in drive capability and edge fidelity |
| 3 TAP 4 | Delayed Output | Delivers input signal delayed by 80ns; shares same output structure and loading specification as TAP1–TAP5 |
| 4 GND | Ground Reference | Primary return path for supply and signal currents; must be low-impedance for timing stability |
| 5 TAP 5 | Delayed Output | Delivers input signal delayed by 100ns; highest-delay tap, subject to ±13% tolerance over temperature |
| 6 TAP 3 | Delayed Output | Delivers input signal delayed by 60ns; middle tap used for symmetric delay interpolation |
| 7 TAP 1 | Delayed Output | Delivers input signal delayed by 20ns; lowest-delay tap, specified with ±4ns absolute tolerance |
| 8 VCC | Power Supply | +3.3V supply input; requires local 0.1µF decoupling to minimize supply-induced jitter |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates aging drift and thermal hysteresis inherent in hybrid or RC-based delay lines |
| Dual-edge precision | Guarantees matched tPLH and tPHL for both leading and trailing edges, enabling accurate pulse-width preservation |
| Monotonic delay tracking | All taps slow or speed together under voltage/temperature change-prevents relative skew inversion in timing chains |
| µMAX footprint | 3mm × 3mm body with 0.65mm pitch enables high-density placement where SO-8 is too large |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-100+ | Same electrical specs and delay values, but in 8-pin SO package (5mm × 4mm) | Requires larger PCB area; better thermal dissipation and hand-solderability | Select when board space allows and SO-8 is preferred for assembly or thermal management |
| ON Semiconductor MC100EP195MNR4G | 5-tap ECL delay line with 3.3V PECL outputs; ±10% delay tolerance; higher power (35mA) | Targets high-speed serial links requiring differential signaling and sub-nanosecond jitter | Select only when PECL interface and tighter jitter performance are required; not drop-in compatible |
Compared with DS1100LZ-100+, the DS1100LU-100+TR saves ~60% board area via µMAX packaging while retaining identical delay accuracy and drive strength; versus MC100EP195MNR4G, it offers lower power and single-ended TTL/CMOS compatibility at the expense of differential signaling and ultra-low jitter.

FAQ
What is the maximum operating frequency supported by DS1100LU-100+TR?
The DS1100LU-100+TR does not specify a maximum operating frequency, but AC characterization uses a 1MHz input signal. Higher frequencies increase ICC and may reduce delay accuracy due to layout sensitivity and decoupling limitations. For reliable operation beyond 1MHz, ensure clean 3.3V supply with local 0.1µF ceramic decoupling and minimize trace inductance on IN and VCC. DS1100LU-100+TR remains functional at higher rates, but timing specifications apply only up to 1MHz per datasheet test conditions.
Does DS1100LU-100+TR support both rising and falling edge delays with equal accuracy?
Yes, DS1100LU-100+TR guarantees matched tPLH and tPHL delays for all five taps, with identical tolerance bands (±4ns for TAP1–TAP3, ±13% for TAP4–TAP5) over –40°C to +85°C. This dual-edge precision ensures pulse-width integrity and makes DS1100LU-100+TR suitable for applications like dead-time generation and logic deskewing where both edges carry timing-critical information.
What is the output drive capability of each tap on DS1100LU-100+TR?
Each tap on DS1100LU-100+TR can drive up to 10 LS-TTL loads, corresponding to an IOL of 8mA (low-level) and IOH of –1mA (high-level) at VCC = 3.0V. This drive strength is verified under open-load conditions and supports direct connection to standard logic families without external buffers. DS1100LU-100+TR maintains this capability across its full operating temperature and voltage range.
Is DS1100LU-100+TR RoHS-compliant and lead-free?
Yes, DS1100LU-100+TR carries the "+" suffix, indicating full RoHS compliance and lead-free construction per Maxim Integrated's packaging standards. The µMAX package uses matte tin plating and meets JEDEC J-STD-020 reflow profiles for lead-free soldering, including peak temperatures up to +260°C. DS1100LU-100+TR is qualified for vapor-phase and IR reflow processes.
How does delay tolerance vary across temperature for DS1100LU-100+TR?
DS1100LU-100+TR specifies delay tolerance as ±4ns for TAP1–TAP3 and ±13% for TAP4–TAP5 over –40°C to +85°C. All taps track unidirectionally-e.g., if TAP1 slows with rising temperature, all others slow proportionally-ensuring monotonic skew behavior. This characteristic simplifies timing margin analysis in thermally varying environments. DS1100LU-100+TR's tolerance is referenced to nominal delay at +25°C and 3.3V.
