Product details
Overview
DS1100U-500+T from Maxim Integrated is a 5-tap silicon delay line in µMAX-8 package, delivering precisely spaced 100ns, 200ns, 300ns, 400ns, and 500ns 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, clock skew correction, and pulse-width adjustment circuits.
For engineers reviewing the DS1100U-500+T datasheet, DS1100U-500+T pinout, DS1100U-500+T application, or DS1100U-500+T equivalent, key selection criteria include tap delay precision across temperature, edge fidelity for high-speed logic interfaces, TTL/CMOS compatibility, low-power CMOS operation, and µMAX packaging for space-constrained PCBs.
Technical Context
The DS1100U-500+T implements an all-silicon delay architecture with five fixed, equally spaced output taps-no external components or configuration required. Each tap delivers deterministic propagation delay referenced to the same input edge, with matched tPLH/tPHL behavior ensuring symmetrical rising/falling edge timing.
It operates strictly at 5V (4.75V–5.25V), supports input pulse widths down to 500ns (per test conditions for -500 version), and maintains delay stability over industrial temperature range (-40°C to +85°C) with ±13% tolerance for delays >40ns and ±4ns absolute tolerance for delays ≤40ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Delays | TAP1=100ns, TAP2=200ns, TAP3=300ns, TAP4=400ns, TAP5=500ns - fixed, monotonic spacing enables predictable signal staging |
| Delay Tolerance | ±4ns (≤40ns taps) or ±13% (＞40ns taps) over -40°C to +85°C - ensures timing margin compliance in industrial environments |
| Supply Voltage | 4.75V to 5.25V - compatible with standard 5V logic rails without regulation overhead |
| Input Compatibility | TTL/CMOS - accepts 0.8V/2.2V logic thresholds, simplifying interface with legacy and modern logic families |
| Output Drive | 12mA sink / -1mA source - sufficient to drive 10× 74LS loads directly, eliminating buffer stages |
| Power Consumption | 30–50mA active current at 1MHz - low static power enables use in power-sensitive timing nodes |
Pinout & Package
DS1100U-500+T is housed in an 8-pin µMAX package (U8+1 outline, 3mm × 3mm, 0.65mm pitch), RoHS-compliant and vapor-phase/wave solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | +5V supply input - decoupling capacitor required within 1cm for stable delay performance |
| 2 | TAP 1 | First delayed output - delivers 100ns post-input edge, usable for early-stage timing reference |
| 3 | TAP 3 | Third delayed output - provides 300ns delay, midpoint in 500ns span for balanced signal interpolation |
| 4 | TAP 5 | Fifth delayed output - final 500ns delay tap, used for maximum latency insertion or pulse stretching |
| 5 | IN | Digital input - accepts TTL/CMOS-compatible pulses ≥500ns wide (for -500 variant) |
| 6 | TAP 2 | Second delayed output - 200ns delay, enables fine-grained step control between TAP1 and TAP3 |
| 7 | TAP 4 | Fourth delayed output - 400ns delay, supports cascaded or dual-edge sampling applications |
| 8 | GND | Ground reference - must be low-impedance return path shared with VCC decoupling |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates hybrid ceramic delay line reliability risks and aging drift; enables full wafer-level test and traceability |
| Leading- and trailing-edge accuracy | Equal tPLH/tPHL tolerance ensures consistent pulse width preservation across all taps - critical for duty-cycle-sensitive logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1000-500+ | Hybrid ceramic delay line; higher aging drift, wider delay tolerance (±15%), larger SO-8 footprint | Limited to commercial temp range (0°C to +70°C); not rated for industrial vibration or long-term stability | Select only if legacy replacement needed and temperature range is restricted to 0°C–70°C |
| MAX9600EUA+ | Programmable 8-tap delay IC; SPI-configurable delays (1–255ns steps); requires external clock and control logic | Supports dynamic delay adjustment but adds MCU dependency and layout complexity | Choose when variable delay or fine-grained tuning is required - not for fixed, low-component-count timing |
Compared with DS1000-500+, DS1100U-500+T offers superior temperature stability and smaller µMAX footprint; compared with MAX9600EUA+, it eliminates firmware, clock routing, and SPI overhead - ideal for cost-sensitive, fixed-delay applications demanding industrial reliability.

FAQ
What is the operating voltage range for DS1100U-500+T?
The DS1100U-500+T operates from 4.75V to 5.25V at nominal 5V supply. This range ensures compatibility with standard 5V logic families and accommodates typical rail tolerances without requiring additional regulation. Operation outside this range may compromise delay accuracy or damage the device, as specified in the Absolute Maximum Ratings section of the DS1100U-500+T datasheet.
Does DS1100U-500+T support both rising and falling edge delays?
Yes, DS1100U-500+T reproduces both leading and trailing edges with equal precision - tPLH and tPHL are matched and specified with identical tolerances (±4ns for ≤40ns taps, ±13% for >40ns taps). This symmetry preserves pulse width integrity across all five taps, making DS1100U-500+T suitable for applications like PWM shaping and glitch filtering where duty cycle fidelity matters.
What is the maximum input frequency supported by DS1100U-500+T?
The DS1100U-500+T is characterized at 1MHz input frequency for DC and AC specifications, with active current (ICC) measured under those conditions. While higher frequencies may be applied, the datasheet notes that delay accuracy degrades near maximum frequency due to layout sensitivity and decoupling effects - thus DS1100U-500+T is best suited for repetitive pulses up to ~1MHz where timing precision is critical.
Can DS1100U-500+T drive standard TTL loads directly?
Yes, DS1100U-500+T can drive up to 10 LS-TTL loads per tap, verified by its IOL = 12mA and IOH = -1mA specifications at VCC min. This capability eliminates the need for external buffers in most logic interfacing scenarios. The DS1100U-500+T output structure is designed for direct connection to 74LS-series inputs, supporting robust fanout without signal degradation.
Is DS1100U-500+T RoHS-compliant and lead-free?
Yes, DS1100U-500+T is RoHS-compliant and lead-free, indicated by the "+" suffix in the part number. It meets JEDEC J-STD-020 reflow profiles for lead-free soldering (peak 260°C) and is qualified for vapor-phase, IR, and wave soldering processes - fully compatible with modern eco-conscious manufacturing requirements.
