Product details
Overview
DS1100LU-500+ from Maxim Integrated is a 3.3V, 5-tap silicon delay line in an 8-pin µMAX package, delivering precisely spaced delays of 100ns, 200ns, 300ns, 400ns, and 500ns at each tap. 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 digital timing alignment, clock skew correction, and pulse-width adjustment circuits.
For engineers reviewing the DS1100LU-500+ datasheet, DS1100LU-500+ pinout, DS1100LU-500+ application, or DS1100LU-500+ equivalent, key selection criteria include guaranteed 500ns maximum tap delay, ±13% delay tolerance over full temperature range, 3.3V CMOS/TTL compatibility, 2.5ns max output rise/fall time, and µMAX package footprint for space-constrained PCBs.
Technical Context
The DS1100LU-500+ implements a monolithic all-silicon delay architecture-no external components or hybrids-ensuring stable propagation delay across voltage (3.0V–3.6V) and temperature (-40°C to +85°C). All five taps track unidirectionally: if one tap slows due to temperature, all slow proportionally, preserving inter-tap spacing integrity.
Each tap delivers TTL-/CMOS-compatible logic levels with 8mA sink and -1mA source capability at minimum VCC, and features 5–10pF input capacitance. Power-up time is 200μs, and active current is 10mA at 1MHz, making it suitable for low-duty-cycle timing control in embedded signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures compatibility with 3.3V logic systems without level-shifting |
| Tap Delays | 100ns / 200ns / 300ns / 400ns / 500ns - fixed, equally spaced delays enabling precise multi-point timing alignment |
| Delay Tolerance | ±13% over -40°C to +85°C - guarantees predictable inter-tap spacing under industrial thermal stress |
| Output Drive | 8mA sink / -1mA source - sufficient to directly drive 10× 74LS loads without buffering |
| Rise/Fall Time | 2.5ns max - preserves signal edge fidelity in sub-ns timing-critical paths |
| Input Capacitance | 10pF typ - minimizes loading on upstream drivers and reduces layout sensitivity |
Pinout & Package
DS1100LU-500+ uses the 8-pin µMAX package (outline U8+1), measuring 3mm × 3mm × 0.8mm with exposed pad for thermal enhancement. Pin 1 is IN, pins 2–5 are TAP 2 through TAP 5, pin 6 is TAP 3, pin 7 is TAP 1, and pin 8 is VCC; GND occupies pin 4. The µMAX package supports vapor-phase and IR reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Signal Input | Accepts TTL/CMOS-compatible logic transitions; 10pF input capacitance minimizes reflection and driver loading |
| TAP 2 (Pin 2) | 200ns Delay Output | Delivers delayed replica of IN with ≤2.5ns edge distortion; drives 10× 74LS loads |
| TAP 4 (Pin 3) | 400ns Delay Output | Provides fourth delay node; same electrical specs as other taps, unidirectionally tracked |
| GND (Pin 4) | Ground Reference | Primary return path for all internal delay circuitry and output drivers; connects to exposed thermal pad |
| TAP 5 (Pin 5) | 500ns Delay Output | Final tap with longest delay; delay accuracy ±13% over full temp/voltage range |
| TAP 3 (Pin 6) | 300ns Delay Output | Mid-range timing node; delay matches nominal value within ±13% under worst-case conditions |
| TAP 1 (Pin 7) | 100ns Delay Output | First tap; enables fine-grained timing offset with same precision as full-scale taps |
| VCC (Pin 8) | Power Supply | +3.3V supply input; decoupling capacitor required within 5mm for stable 10mA switching current |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-500+ | Same delay values and specs, but in 8-pin SO (150-mil) package instead of µMAX | Requires larger PCB footprint; better thermal dissipation but less board-area efficient | Select when SO-8 is preferred for legacy layout compatibility or manual assembly |
| ON Semiconductor MC100EP195MNR4G | 5-tap ECL delay line with 0.35ns resolution; requires -3.3V supply and level translation for 3.3V systems | Higher precision but incompatible voltage domain; suited for RF/microwave timing, not general-purpose logic | Select only for ultra-low-jitter ECL environments where DS1100LU-500+ lacks required resolution |
Compared with DS1100LZ-500+, the DS1100LU-500+ saves >50% board area while maintaining identical delay performance; compared with MC100EP195MNR4G, it eliminates negative supply and level-shifting overhead but trades off sub-nanosecond resolution for ease of integration in 3.3V digital systems.

FAQ
What is the operating temperature range for DS1100LU-500+?
The DS1100LU-500+ is specified to operate from -40°C to +85°C. Its delay tolerances, output drive strength, and power consumption are guaranteed across this full industrial temperature range. All five taps maintain proportional delay shifts-ensuring consistent 100ns spacing between taps regardless of ambient conditions. This makes DS1100LU-500+ suitable for deployment in harsh-environment industrial controllers and outdoor communication equipment.
Does DS1100LU-500+ support both rising and falling edge delay accuracy?
Yes, DS1100LU-500+ is explicitly designed to reproduce both leading and trailing edges with equal precision. Its internal all-silicon architecture ensures matched tPLH and tPHL delays across all taps, with ±4ns tolerance for delays ≤40ns and ±13% for longer delays like the 500ns tap. This dual-edge fidelity allows DS1100LU-500+ to preserve pulse width integrity in applications such as digital waveform shaping and glitch filtering.
Can DS1100LU-500+ drive standard TTL loads directly?
Yes, DS1100LU-500+ can drive up to 10 LS-TTL loads per tap without external buffers. Its output stage delivers 8mA sink current and -1mA source current at minimum VCC (3.0V), meeting the DC interface requirements of 74LS-series logic. This capability simplifies system design by eliminating intermediate buffer stages in timing distribution networks where DS1100LU-500+ is deployed.
Is DS1100LU-500+ RoHS-compliant and lead(Pb)-free?
Yes, the "+" suffix in DS1100LU-500+ denotes a lead(Pb)-free and RoHS-compliant µMAX package. It is qualified for reflow soldering at +260°C (lead-free profile) and meets JEDEC J-STD-020 moisture sensitivity level MSL-1. The device carries no exemptions and complies fully with EU RoHS Directive 2011/65/EU and China RoHS II.
How does DS1100LU-500+ differ from the DS1100LZ-500+ variant?
DS1100LU-500+ and DS1100LZ-500+ share identical electrical specifications-including 100ns–500ns tap delays, ±13% tolerance, and 3.0V–3.6V operation-but differ exclusively in package: DS1100LU-500+ uses the 3mm × 3mm µMAX (U8+1), while DS1100LZ-500+ uses the larger 150-mil SO-8 (S8+4). The µMAX version offers superior board-area efficiency and is optimized for high-density layouts, whereas the SO-8 variant eases hand-soldering and thermal management.
