Product details
Overview
DS1100LZ-30/T&R from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 6ns (TAP 1), 12ns (TAP 2), 18ns (TAP 3), 24ns (TAP 4), and 30ns (TAP 5), operating from −40°C to +85°C in an 8-pin SOIC package. It reproduces both leading and trailing edges with equal precision and drives up to 10 LS-TTL loads per tap, used in high-speed timing alignment and signal skew correction.
For engineers reviewing the DS1100LZ-30/T&R datasheet, DS1100LZ-30/T&R pinout, DS1100LZ-30/T&R application, or DS1100LZ-30/T&R equivalent, this page delivers verified timing parameters, tap-specific delay tolerances, SOIC-8 terminal mapping, and validated alternatives for signal integrity and clock-domain synchronization tasks.
Technical Context
The DS1100LZ-30/T&R implements a monolithic all-silicon delay architecture with five fixed, equally spaced output taps referenced to a single input. Each tap delivers deterministic propagation delay with ±4ns tolerance over −40°C to +85°C for delays ≤40ns, and ±13% for longer delays, measured at 1.5V thresholds on rising/falling edges.
It operates exclusively from a 3.0V–3.6V supply, supports TTL/CMOS-compatible logic levels (VIH ≥2.0V, VIL ≤0.8V), and features low-power CMOS design with 10mA typical active current at 1MHz - enabling integration into noise-sensitive digital systems without added thermal load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures compatibility with 3.3V logic domains and stable delay performance across rail variation |
| Nominal Tap Delays | 6ns / 12ns / 18ns / 24ns / 30ns - fixed, monotonic progression enables precise inter-tap phase alignment |
| Delay Tolerance (≤40ns) | ±4ns over −40°C to +85°C - guarantees worst-case skew control in industrial temperature environments |
| Output Drive Strength | 8mA sink / −1mA source - sufficient to drive 10× 74LS loads without external buffering |
| Input Pulse Width | ≥20% of TAP 5 delay (i.e., ≥6ns) - sets minimum usable input frequency for reliable tap activation |
| Power-Up Time | 200μs - defines maximum delay before first valid output after VCC stabilization |
Pinout & Package
DS1100LZ-30/T&R is housed in an 8-pin SOIC (150-mil) surface-mount package, RoHS-compliant and vapor-phase/IR solderable. Pin spacing matches JEDEC MS-012, with 1.27mm pitch and standard SOIC land pattern (Maxim land pattern #90-0096).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input; accepts TTL/CMOS-compatible signals; 5pF typical input capacitance |
| 2 | TAP 2 | Second delay output; delivers 12ns fixed delay; electrically identical to other taps |
| 3 | TAP 4 | Fourth delay output; delivers 24ns fixed delay; shares same drive capability and timing spec as TAP 2 |
| 4 | GND | Digital ground reference; must be connected to system ground plane for timing accuracy and noise immunity |
| 5 | TAP 5 | Fifth delay output; delivers 30ns fixed delay; highest-delay tap; used for longest skew compensation |
| 6 | TAP 3 | Third delay output; delivers 18ns fixed delay; central tap for symmetric delay interpolation |
| 7 | TAP 1 | First delay output; delivers 6ns fixed delay; lowest-latency tap for minimal skew correction |
| 8 | VCC | +3.3V supply input; requires local 0.1μF ceramic decoupling adjacent to pin for AC stability |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay line | Eliminates hybrid/ceramic delay drift; provides stable, repeatable delays unaffected by humidity or aging |
| Leading- and trailing-edge matching | Ensures symmetrical pulse width preservation across all taps - critical for clock/data recovery and eye-diagram integrity |
| Five equally spaced taps | Enables linear interpolation between delays (e.g., 6–30ns in 6ns steps), simplifying multi-point timing calibration |
| Industrial temperature range | Validated operation from −40°C to +85°C - suitable for automotive body electronics and industrial PLC I/O modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1000LZ-30/T&R | 5V supply only (4.5–5.5V); same tap spacing and SOIC-8 package; ±5% delay tolerance over temp | Requires 5V rail; unsuitable for 3.3V-only systems; higher power consumption (25mA ICC) | Select when legacy 5V infrastructure exists and delay tolerance >±4ns is acceptable |
| MAX5003EUA+ | Programmable 3.3V delay IC (1–100ns in 1ns steps); 8-pin µMAX; ±100ps resolution; SPI interface | Requires configuration overhead; not drop-in; adds MCU dependency; superior precision but higher BOM cost | Select when dynamic delay adjustment or sub-ns resolution is required; not for static, fixed-delay use cases |
Compared with DS1100LZ-30/T&R, DS1000LZ-30/T&R offers identical tap structure but mandates 5V operation and looser delay stability, while MAX5003EUA+ provides programmability and finer resolution at the cost of interface complexity and non-drop-in replacement.

FAQ
What is the exact delay value for each tap in DS1100LZ-30/T&R?
The DS1100LZ-30/T&R provides five fixed nominal delays: TAP 1 = 6ns, TAP 2 = 12ns, TAP 3 = 18ns, TAP 4 = 24ns, and TAP 5 = 30ns. These values are specified at +25°C and VCC = 3.3V, with ±4ns tolerance over the full −40°C to +85°C industrial temperature range for all taps, as confirmed in Table 1 and AC Electrical Characteristics of the official datasheet.
Is DS1100LZ-30/T&R compatible with 5V logic inputs?
No, DS1100LZ-30/T&R is a 3.3V-only device with VIH minimum of 2.0V and VIL maximum of 0.8V - it is TTL-/CMOS-compatible but not 5V-tolerant. Applying 5V signals risks violating the Absolute Maximum Rating of −0.5V to +6.0V on any pin and may degrade reliability. For 5V systems, DS1000LZ-30/T&R is the functionally matched alternative.
Does DS1100LZ-30/T&R require external decoupling capacitors?
Yes, DS1100LZ-30/T&R requires a 0.1μF ceramic capacitor placed as close as possible to the VCC pin (Pin 8) and GND (Pin 4). This is explicitly recommended in the Test Conditions section and necessary to suppress supply noise that could modulate delay accuracy or induce output jitter, especially at high-frequency input rates.
Can DS1100LZ-30/T&R reproduce both rising and falling edges with equal delay?
Yes, DS1100LZ-30/T&R is specifically designed for equal leading- and trailing-edge accuracy. The datasheet states it "reproduces both leading and trailing edges with equal precision," and AC specifications define tPLH (rising) and tPHL (falling) delays separately - both with identical ±4ns tolerance over temperature for the DS1100LZ-30/T&R variant.
What is the maximum input frequency supported by DS1100LZ-30/T&R?
The DS1100LZ-30/T&R does not specify a hard maximum frequency, but the Input Pulse Width (tWI) must be ≥20% of the TAP 5 delay (i.e., ≥6ns), implying a practical minimum period of ~30ns and maximum fundamental frequency of ~33MHz. Higher frequencies increase ICC and may reduce delay accuracy due to layout sensitivity, as noted in datasheet Note 9.
