Product details
Overview
DS1100LZ-50+ from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 10ns, 20ns, 30ns, 40ns, and 50ns across TAP1–TAP5. It operates from −40°C to +85°C, delivers TTL-/CMOS-compatible outputs, and drives up to 10 × 74LS loads per tap. Used in high-speed timing alignment, clock skew correction, and pulse-width adjustment in industrial control and test equipment.
For engineers reviewing the DS1100LZ-50+ datasheet, DS1100LZ-50+ pinout, DS1100LZ-50+ application, or DS1100LZ-50+ equivalent, key selection factors include tap delay precision (±4ns over full temperature range), 3.3V supply compatibility, SO-8 package footprint, leading/trailing edge fidelity, and 50mA absolute max output short-circuit rating.
Technical Context
The DS1100LZ-50+ implements an all-silicon delay architecture with five fixed, equally spaced taps-no external components or trimming required. Delay accuracy is specified as ±4ns for delays ≤40ns and ±13% for delays >40ns over −40°C to +85°C, with unidirectional drift across taps under voltage/temperature variation.
It features CMOS input with VIH ≥2.0V and VIL ≤0.8V, low-power operation (10mA typical ICC at 1MHz), and fast output transitions (2.0–2.5ns rise/fall). Each tap reproduces both logic edges with equal precision, enabling accurate pulse shaping and timing window generation in synchronous digital systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures stable operation in 3.3V rail systems without level-shifting. |
| Nominal Tap Delays | 10ns / 20ns / 30ns / 40ns / 50ns - fixed, calibrated delays for precise signal alignment. |
| Delay Tolerance | ±4ns (TAP1–TAP4), ±13% (TAP5) over −40°C to +85°C - enables deterministic timing margining. |
| Output Drive | 8mA sink / −1mA source - sufficient to drive 10 × 74LS loads without buffering. |
| Input Pulse Width | ≥20% of TAP5 delay (i.e., ≥10ns) - sets minimum usable input frequency and pulse integrity. |
| Power-Up Time | 200μs - defines minimum reset-to-valid-output latency after power stabilization. |
Pinout & Package
DS1100LZ-50+ is housed in an 8-pin SO (150-mil) surface-mount package, RoHS-compliant and lead(Pb)-free, with standard JEDEC SOIC-8 footprint (outline 21-0041, land pattern 90-0096).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Input Signal | Accepts TTL-/CMOS-compatible logic pulses; 5pF input capacitance minimizes loading on driving stage. |
| 2 TAP 2 | Delay Output | Delivers input signal delayed by 20ns; identical edge fidelity for setup/hold timing validation. |
| 3 TAP 4 | Delay Output | Delivers input signal delayed by 40ns; supports dual-edge sampling windows in high-speed capture circuits. |
| 4 GND | Ground Reference | Common return path for all I/O and internal circuitry; requires low-impedance PCB connection. |
| 5 TAP 5 | Delay Output | Delivers input signal delayed by 50ns; highest delay tap, used for maximum skew compensation. |
| 6 TAP 3 | Delay Output | Delivers input signal delayed by 30ns; central tap for symmetric delay interpolation or mid-point triggering. |
| 7 TAP 1 | Delay Output | Delivers input signal delayed by 10ns; shortest delay for fine-grained timing adjustments. |
| 8 VCC | Supply Input | +3.3V power rail; decoupling capacitor (0.1μF) recommended adjacent to pin for noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay line | Eliminates hybrid ceramic or SAW-based drift and aging; guarantees long-term stability in field-deployed systems. |
| Equal-precision leading/trailing edge delay | Enables accurate pulse-width preservation and duty-cycle integrity in timing-critical waveform generation. |
| Five fixed, calibrated taps | Provides discrete, repeatable delay points without external tuning components or calibration routines. |
| Vapor-phase and IR solderable | Supports standard reflow profiles including Pb-free (260°C) and SnPb (240°C) processes without reliability risk. |
| −40°C to +85°C industrial temperature range | Validated performance across extended thermal environments common in factory automation and outdoor electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-50 | Same electrical specs and delay values; non-RoHS, SnPb finish. | Not suitable for new designs requiring RoHS compliance or lead-free assembly. | Select DS1100LZ-50+ when Pb-free process control and environmental certification are mandatory. |
| DS1100LU-50+ | Identical delay and timing specs; uses 8-pin µMAX (U8+1) package (3mm × 3mm vs SO-8's 4.9mm × 6.0mm). | Preferred where board space is constrained and thermal dissipation allows smaller footprint. | Choose DS1100LU-50+ for compact, high-density layouts; DS1100LZ-50+ for legacy SO-8 compatibility and thermal margin. |
Compared with DS1100LZ-50 and DS1100LU-50+, the DS1100LZ-50+ offers RoHS-compliant manufacturing in the industry-standard SO-8 package-providing optimal balance of supply chain readiness, thermal performance, and regulatory compliance for volume industrial deployments.

FAQ
What is the operating voltage range for DS1100LZ-50+?
The DS1100LZ-50+ operates from 3.0V to 3.6V, optimized for 3.3V systems. Operation outside this range risks violating absolute maximum ratings-including −0.5V to +6.0V on any pin-and may cause timing inaccuracy or permanent damage. The device draws 10mA typical active current at 1MHz under VCC = 3.3V, making it suitable for low-power industrial designs where rail stability is maintained within specification.
How precise are the tap delays on DS1100LZ-50+ across temperature?
For DS1100LZ-50+, tap delays ≤40ns (TAP1–TAP4) maintain ±4ns tolerance over −40°C to +85°C, while TAP5 (50ns) holds ±13% tolerance. This is measured at the 1.5V logic threshold with 3.3V supply. All taps track unidirectionally-e.g., if TAP1 slows with temperature, all others slow proportionally-enabling predictable system-level timing margining without per-tap recalibration.
Can DS1100LZ-50+ drive standard TTL logic directly?
Yes, DS1100LZ-50+ can drive up to 10 × 74LS loads per tap, meeting TTL voltage thresholds (VIH ≥2.0V, VIL ≤0.8V) and current requirements (IOL = 8mA, IOH = −1mA). Its outputs are fully TTL-/CMOS-compatible, eliminating need for level shifters in mixed-logic systems. However, for heavier loads or longer traces, verify signal integrity via simulation or measurement due to 2.0–2.5ns output transition times and 5pF input capacitance.
What is the significance of the "+" suffix in DS1100LZ-50+?
The "+" suffix in DS1100LZ-50+ denotes a lead(Pb)-free, RoHS-compliant SO-8 package. It specifies a Pb-free finish compatible with IPC/JEDEC J-STD-020D reflow profiles (peak 260°C). This distinguishes it from DS1100LZ-50 (SnPb, 240°C peak), ensuring compliance with environmental regulations and modern assembly standards without altering electrical or timing behavior of the DS1100LZ-50+ device.
Is DS1100LZ-50+ pin-compatible with other DS1100L variants?
Yes, all DS1100LZ-xxx+ variants share identical SO-8 pinout and electrical interface-only nominal delay values differ across TAP1–TAP5. For example, DS1100LZ-50+ and DS1100LZ-100+ use the same pin assignments (IN, TAP1–TAP5, VCC, GND), allowing layout reuse across delay requirements. This simplifies BOM rationalization and enables design flexibility during prototyping and production ramp without PCB revision.
