Product details
Overview
DS1100LZ-50+T from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 10ns (TAP 1), 20ns (TAP 2), 30ns (TAP 3), 40ns (TAP 4), and 50ns (TAP 5), operating from −40°C to +85°C in an 8-pin SO 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-50+T datasheet, DS1100LZ-50+T pinout, DS1100LZ-50+T application, or DS1100LZ-50+T equivalent, key selection criteria include tap delay accuracy (±4ns over full temperature range for ≤40ns delays), 3.3V CMOS/TTL compatibility, low-power operation (10mA typical ICC), and industrial-grade thermal stability.
Technical Context
The DS1100LZ-50+T implements a monolithic all-silicon delay architecture-no hybrid or ceramic components-ensuring stable propagation delay across voltage (3.0V–3.6V) and temperature (−40°C to +85°C). Each of its five taps delivers fixed, equally spaced delays referenced to the input edge at the 1.5V threshold.
Delay tolerance is specified as ±4ns (for TAP 1–TAP 5, all ≤40ns) over the full industrial temperature range, with unidirectional drift: if one tap slows with temperature, all others slow proportionally. Output rise/fall time is 2.0ns to 2.5ns, and power-up time is 200μs.
Key Specifications

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 pinout; differs only in packaging format (tube vs. tape-and-reel) | No functional difference; suitable for prototyping or low-volume hand assembly | Select DS1100LZ-50+T when automated SMT placement or volume production is required |
| DS1100LU-50+T | Identical delay values and timing specs; uses 8-pin µMAX (U8+1) package instead of SO (S8+4) | Requires different PCB footprint and land pattern; smaller board area but tighter layout constraints | Choose DS1100LU-50+T only when space-constrained designs justify µMAX requalification |
Compared with DS1100LZ-50+, the DS1100LZ-50+T offers identical timing performance and electrical behavior but ships in tape-and-reel format for SMT line integration; versus DS1100LU-50+T, it trades compactness for easier handling, thermal dissipation, and legacy footprint compatibility.

FAQ
What is the nominal delay value for each tap of the DS1100LZ-50+T?
The DS1100LZ-50+T provides five fixed, equally spaced delays: TAP 1 = 10ns, TAP 2 = 20ns, TAP 3 = 30ns, TAP 4 = 40ns, and TAP 5 = 50ns, all referenced to the 1.5V input threshold. These values are guaranteed at +25°C and VCC = 3.3V, with tolerances scaling per temperature and voltage conditions as specified in the DS1100L datasheet.
Does the DS1100LZ-50+T support both rising and falling edge delays?
Yes, the DS1100LZ-50+T is explicitly designed to reproduce both leading and trailing edges with equal precision. Its tPLH (rising) and tPHL (falling) delays are matched within ±4ns over the full industrial temperature range, ensuring pulse-width fidelity critical for clock distribution and data strobing applications.
What is the maximum load drive capability per tap on the DS1100LZ-50+T?
Each tap of the DS1100LZ-50+T can drive up to 10 LS-TTL loads, defined as the input capacitance and current requirements of a standard 74LS gate. This specification assumes VCC = 3.0V minimum and operation within the −40°C to +85°C range, and is verified under open-load DC conditions per the DS1100L datasheet test methodology.
Is the DS1100LZ-50+T RoHS-compliant and lead(Pb)-free?
Yes, the "+T" suffix in DS1100LZ-50+T indicates a lead(Pb)-free, RoHS-compliant 8-pin SOIC package. It is qualified for vapor-phase and IR reflow soldering, with a peak reflow temperature of +260°C for lead-free processes, and meets JEDEC J-STD-020 moisture sensitivity level MSL-1.
Can the DS1100LZ-50+T operate outside the 3.3V nominal supply range?
The DS1100LZ-50+T is characterized for operation from 3.0V to 3.6V. Operation below 3.0V may cause timing degradation or failure to meet delay specifications; operation above 3.6V exceeds absolute maximum ratings and risks permanent damage. The device must be powered within this window to guarantee the ±4ns delay tolerance and 10 LS-TTL drive capability.
