Product details
Overview
DS1100U-50+ from Maxim Integrated is a 5-tap silicon delay line in µMAX-8 package, delivering precise 10ns/20ns/30ns/40ns/50ns fixed delays per tap with ±4ns tolerance over -40°C to +85°C, 5V operation, and TTL/CMOS compatibility for digital timing alignment in test equipment and logic synchronization circuits.
For engineers reviewing the DS1100U-50+ datasheet, DS1100U-50+ pinout, DS1100U-50+ application, or DS1100U-50+ equivalent, key selection factors include tap delay accuracy across temperature, 5V supply stability, output drive capability (10 × 74LS loads), and µMAX-8 footprint compatibility with high-density PCB layouts.
Technical Context
The DS1100U-50+ implements an all-silicon delay architecture with five equally spaced taps, each reproducing both leading and trailing edges of the input signal with matched precision. Delay values are factory-trimmed and specified at 10ns/20ns/30ns/40ns/50ns for TAP1–TAP5 respectively, with initial tolerance ±2ns at +25°C and ±4ns over full industrial temperature range.
It operates exclusively at 5V (4.75V–5.25V), draws 30–50mA active current, and supports standard soldering processes including lead-free reflow up to +260°C. Input pulse width must exceed 20% of TAP5 delay (i.e., ≥10ns), and outputs are characterized at 1.5V switching threshold under 74F04-equivalent load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Delays (TAP1–TAP5) | 10ns / 20ns / 30ns / 40ns / 50ns - fixed, equally spaced timing offsets for multi-point signal alignment |
| Delay Tolerance | ±4ns (–40°C to +85°C) - ensures consistent phase margin in synchronous logic paths |
| Supply Voltage | 4.75V–5.25V - compatible with standard 5V logic rails without regulation overhead |
| Output Drive | 12mA sink / –1mA source - sufficient to drive 10 × 74LS inputs without buffering |
| Input Capacitance | 5–10pF - minimizes loading on upstream clock or data sources |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded and test instrumentation use |
| Power-Up Time | 200μs - defines minimum reset-to-valid-output latency after VCC stabilization |
Pinout & Package
DS1100U-50+ uses the 8-pin µMAX package (U8+1 outline, 3mm × 3mm body, 0.65mm pitch), optimized for space-constrained PCBs. Pin 1 is IN, pins 2–6 are TAP1–TAP5, pin 7 is VCC, and pin 8 is GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Signal Input | Accepts TTL/CMOS-compatible 5V logic edge; drives internal delay chain |
| TAP 1 | First Delay Output | Delivers input signal delayed by 10ns; used for shortest-path timing correction |
| TAP 2 | Second Delay Output | Delivers input signal delayed by 20ns; enables intermediate skew adjustment |
| TAP 3 | Third Delay Output | Delivers input signal delayed by 30ns; central tap for symmetric delay distribution |
| TAP 4 | Fourth Delay Output | Delivers input signal delayed by 40ns; supports longer-path synchronization |
| TAP 5 | Fifth Delay Output | Delivers input signal delayed by 50ns; maximum delay tap for full-range alignment |
| VCC | Power Supply | +5V supply pin; requires local 0.1μF bypass capacitor near pin |
| GND | Ground Reference | Common return path for all internal circuitry and output loads |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates hybrid ceramic delay line reliability risks and enables wafer-level testing |
| Leading- and trailing-edge matching | Ensures duty-cycle preservation across all taps-critical for clock distribution and pulse shaping |
| 5V-only operation | Simplifies power architecture by avoiding dual-supply or level-shifting circuitry |
| µMAX-8 footprint | Reduces board area by >60% vs. SO-8 while maintaining hand-solderability and reflow compatibility |
| Stable delay over temp/voltage | Unidirectional delay drift ensures monotonic timing behavior-no tap inversion or crossover |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1000Z-50+ | Hybrid ceramic delay line; ±10ns tolerance over temperature; higher cost; larger SO-8 footprint | Legacy replacement only; lacks leading/trailing edge matching; not recommended for new designs | Select DS1100U-50+ for improved accuracy, smaller size, and lower cost in new industrial timing designs |
| SY100ELT22LZG | PECL-output ECL delay IC; 3.3V operation; adjustable delay via external resistor; no multi-tap outputs | Requires level translation for 5V systems; single-delay output limits multi-point alignment capability | Choose DS1100U-50+ when fixed 5-tap 5V delay with guaranteed edge matching is required |
Compared with DS1000Z-50+, DS1100U-50+ delivers tighter delay tolerance (±4ns vs. ±10ns), smaller µMAX-8 footprint, and superior edge fidelity-making it optimal for high-precision, space-constrained 5V timing. Versus SY100ELT22LZG, DS1100U-50+ provides native 5V multi-tap delay without level-shifting or external components.

FAQ
What is the nominal delay value for each tap of the DS1100U-50+?
The DS1100U-50+ provides five fixed, equally spaced delays: TAP1 = 10ns, TAP2 = 20ns, TAP3 = 30ns, TAP4 = 40ns, and TAP5 = 50ns. These values are factory-trimmed and specified at +25°C and 5V, with tolerance tightening to ±4ns over the full –40°C to +85°C industrial temperature range. Each tap reproduces both rising and falling edges with matched delay.
Is the DS1100U-50+ compatible with 3.3V logic systems?
No, the DS1100U-50+ is strictly a 5V-only device, with absolute maximum VCC of +6.0V and minimum operating VCC of 4.75V. Its input thresholds (VIH ≥ 2.2V, VIL ≤ 0.8V) and output drive characteristics are optimized for TTL/CMOS 5V interfaces. Interfacing with 3.3V systems requires level translation; the DS1100U-50+ itself does not support 3.3V operation.
Can the DS1100U-50+ drive standard 74LS logic inputs directly?
Yes, the DS1100U-50+ can drive up to 10 × 74LS loads per tap, as confirmed in the General Description and AC Electrical Characteristics sections. Its output sink current (IOL = 12mA min) and source current (IOH = –1mA min) meet 74LS input requirements under worst-case conditions, eliminating the need for external buffers in typical logic interfacing applications.
What is the significance of the "+" suffix in DS1100U-50+?
The "+" suffix in DS1100U-50+ indicates a lead(Pb)-free and RoHS-compliant µMAX-8 package, per Maxim's ordering nomenclature. This version supports lead-free reflow soldering up to +260°C and conforms to environmental compliance standards without altering electrical performance or timing specifications compared to non-RoHS variants.
Does the DS1100U-50+ require external passive components for stable operation?
The DS1100U-50+ requires only a 0.1μF ceramic bypass capacitor placed as close as possible to the VCC and GND pins for stable operation. No external resistors, capacitors, or trim components are needed-the delays are fully internal and factory-calibrated. The device is designed for plug-and-play integration into 5V digital timing paths without supporting circuitry.
