Product details
Overview
DS1100U-40+ from Maxim Integrated is a 5-tap silicon delay line in an 8-pin µMAX package, delivering precisely spaced 8ns, 16ns, 24ns, 32ns, and 40ns delays at 5V operation. 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 serves in digital timing alignment, pulse shaping, and clock deskewing applications.
For engineers reviewing the DS1100U-40+ datasheet, DS1100U-40+ pinout, DS1100U-40+ application, or DS1100U-40+ equivalent, key selection considerations include tap delay precision across temperature, TTL/CMOS compatibility, low-power CMOS operation, µMAX footprint constraints, and industrial-grade reliability without hybrid construction.
Technical Context
The DS1100U-40+ implements an all-silicon delay architecture with five fixed, equally spaced output taps referenced to a single input. Each tap delivers deterministic propagation delay with matched tPLH/tPHL characteristics and unidirectional drift under voltage or temperature variation.
It operates exclusively at 5V (4.75V–5.25V), supports 1MHz maximum input frequency, and maintains edge fidelity via 1.5V-level timing measurement points. Input pulse width must exceed 20ns (tWI ≥ 20ns), and power-up stabilization completes within 200μs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Tap Delays | 8ns / 16ns / 24ns / 32ns / 40ns - fixed, equally spaced delays for sequential signal alignment |
| Delay Tolerance (–40°C to +85°C) | ±4ns for ≤40ns delays - ensures timing margin stability across full industrial temperature range |
| Supply Voltage | 4.75V to 5.25V - compatible with standard 5V logic rails and decoupling practices |
| Input Compatibility | TTL/CMOS - accepts 0.8V VIH threshold and drives 74LS loads directly without level-shifting |
| Output Drive Capability | 12mA sink / –1mA source - sufficient for 10× 74LS inputs per tap under worst-case VCC min |
| Power Consumption | 30mA to 50mA ICC - low quiescent current enables use in power-sensitive digital subsystems |
| Input Capacitance | 5pF to 10pF - minimizes loading on preceding stage and preserves high-speed signal integrity |
Pinout & Package
DS1100U-40+ uses an 8-pin µMAX package (U8+1 outline, 3mm × 3mm body, 0.65mm pitch), RoHS-compliant and vapor-phase solderable. Pin 1 is IN, pins 2–6 are TAP 1 through TAP 5, pin 7 is VCC, and pin 8 is GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Signal Input | Single-ended logic input accepting TTL/CMOS levels; triggers all five delay paths simultaneously |
| TAP 1 | First Delay Output | Delivers input signal after 8ns fixed delay; used for shortest-path timing correction |
| TAP 2 | Second Delay Output | Delivers input signal after 16ns fixed delay; enables mid-range skew compensation |
| TAP 3 | Third Delay Output | Delivers input signal after 24ns fixed delay; provides central reference point in 5-tap sequence |
| TAP 4 | Fourth Delay Output | Delivers input signal after 32ns fixed delay; supports cascaded or multi-stage alignment |
| TAP 5 | Fifth Delay Output | Delivers input signal after 40ns fixed delay; used for longest-path matching or pulse width extension |
| VCC | Power Supply | +5V supply pin; requires local 0.1μF ceramic decoupling adjacent to pin 7 |
| GND | Ground Reference | Common return path for all internal delay elements and output drivers; connects to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay core | Eliminates hybrid packaging drift and aging; ensures long-term delay stability vs. ceramic or SAW alternatives |
| Equal tap spacing | Enables linear interpolation between taps and predictable phase relationships in multi-tap timing chains |
| Leading- and trailing-edge accuracy | Guarantees matched tPLH/tPHL delay values - critical for pulse-width preservation in data strobes or clock enables |
| Industrial temperature range support | Validated operation from –40°C to +85°C without derating - suitable for automotive control modules and industrial PLCs |
| µMAX surface-mount package | 3mm × 3mm footprint saves PCB area vs. SO-8; compatible with automated reflow and wave soldering processes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1000Z-40+ | Hybrid construction; ±10ns delay tolerance over –40°C to +85°C; higher temperature coefficient | Limited to commercial-grade environments; less stable under thermal cycling | Select DS1000Z-40+ only if legacy hybrid design reuse is required and tighter delay tolerance is not critical |
| MAX9601EUA+ | Programmable 1–100ns delay in 1ns steps; serial interface; 8-pin μMAX; 3.3V/5V dual-supply capable | Requires configuration interface and firmware; adds complexity but enables dynamic delay adjustment | Choose MAX9601EUA+ when adaptive delay tuning or field calibration is needed beyond fixed-tap capability |
Compared with DS1000Z-40+, DS1100U-40+ offers superior delay stability and lower temperature drift due to its all-silicon architecture; compared with MAX9601EUA+, it provides simpler, zero-configuration timing with guaranteed edge-matching but lacks programmability.

FAQ
What is the nominal delay value for each tap of the DS1100U-40+?
The DS1100U-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 specified at +25°C and 5V, with ±4ns tolerance over the full –40°C to +85°C operating range. All delays scale uniformly with temperature and supply voltage changes, preserving relative spacing.
Is the DS1100U-40+ compatible with 3.3V logic systems?
No, the DS1100U-40+ is designed strictly for 5V operation (4.75V–5.25V). Its input thresholds (VIH = 2.2V min, VIL = 0.8V max) and output drive levels are optimized for TTL/CMOS 5V families. Connecting it to a 3.3V system without level translation risks unreliable switching and violates absolute maximum ratings on input pins.
Does the DS1100U-40+ require external decoupling capacitors?
Yes, DS1100U-40+ requires a 0.1μF ceramic capacitor placed as close as possible between VCC (pin 7) and GND (pin 8). This decoupling suppresses supply noise induced by simultaneous tap switching and ensures stable delay performance, especially at higher input frequencies approaching 1MHz.
Can the DS1100U-40+ reproduce both rising and falling edges with equal accuracy?
Yes, DS1100U-40+ guarantees matched leading-edge (tPLH) and trailing-edge (tPHL) delays across all five taps. The datasheet specifies identical ±4ns tolerance for both parameters over –40°C to +85°C, ensuring pulse-width integrity and eliminating duty-cycle distortion in timing-critical paths.
What is the maximum load each tap of the DS1100U-40+ can drive?
Each tap of the DS1100U-40+ can drive up to 10 standard 74LS logic inputs, corresponding to a 12mA sink current (IOL) and –1mA source current (IOH) under worst-case VCC = 4.75V conditions. Exceeding this load increases propagation delay uncertainty and may violate output voltage specifications.
