Product details
Overview
DS1100LZ-125 from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 25ns (TAP1), 50ns (TAP2), 75ns (TAP3), 100ns (TAP4), and 125ns (TAP5), operating across -40°C to +85°C, driving up to 10 LS-TTL loads per tap, and housed in an 8-pin SOIC package.
For engineers reviewing the DS1100LZ-125 datasheet, DS1100LZ-125 pinout, DS1100LZ-125 application, or DS1100LZ-125 equivalent, key selection criteria include tap delay precision over temperature/voltage, leading/trailing edge matching, TTL/CMOS compatibility, low-power CMOS operation, and industrial-grade reliability in surface-mount timing circuits.
Technical Context
The DS1100LZ-125 implements a monolithic all-silicon delay architecture with five fixed, equally spaced output taps referenced to a single input signal. Each tap reproduces both rising and falling edges with matched propagation delay tolerance-±4ns for delays ≤40ns and ±13% for delays >40ns over full temperature range.
It operates from 3.0V to 3.6V, draws ≤10mA active current at 1MHz, and features 5pF typical input capacitance, 2.0–2.5ns output rise/fall times, and 200μs power-up time. All outputs are fully buffered and specified for 74LS load drive capability without external termination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures stable operation in 3.3V systems with ±10% rail tolerance |
| Nominal Tap Delays | 25ns / 50ns / 75ns / 100ns / 125ns - fixed, calibrated delays enabling precise signal alignment in digital timing paths |
| Delay Tolerance | ±4ns (TAP1–TAP3) or ±13% (TAP4–TAP5) over -40°C to +85°C - guarantees predictable skew between taps under thermal stress |
| Output Drive | Up to 10 × 74LS loads per tap - eliminates need for external buffers in legacy TTL interfacing |
| Input/Output Compatibility | TTL- and CMOS-compatible logic levels - supports mixed-logic system integration without level-shifting |
| Power Consumption | ≤10mA ICC at 1MHz - enables low-power timing in battery-backed or energy-constrained embedded designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-100 | Fixed 20/40/60/80/100ns tap delays - shorter maximum delay than DS1100LZ-125 | Suitable when 100ns max delay suffices and tighter delay granularity is needed below 100ns | Select DS1100LZ-100 if system timing budget requires sub-125ns maximum alignment window |
| DS1100LU-125 | Same delay values but in 8-pin µMAX (3mm × 3mm) package - 60% smaller footprint than SOIC | Better suited for space-constrained portable or modular electronics where board area is critical | Choose DS1100LU-125 when PCB real estate is limited and reflow-compatible packaging is acceptable |

FAQ
What is the operating voltage range for DS1100LZ-125?
The DS1100LZ-125 operates from 3.0V to 3.6V, making it compatible with standard 3.3V logic systems. Its specifications-including delay tolerance, output drive, and current consumption-are guaranteed across this full supply range and over the industrial temperature range of -40°C to +85°C. The DS1100LZ-125 does not support 5V operation.
How accurate are the tap delays on DS1100LZ-125 across temperature?
For DS1100LZ-125, tap delays TAP1 through TAP3 (25ns, 50ns, 75ns) have a tolerance of ±4ns over -40°C to +85°C, while TAP4 (100ns) and TAP5 (125ns) have ±13% tolerance. This reflects the datasheet's distinction between absolute nanosecond error for shorter delays and percentage-based error for longer ones, ensuring predictable relative skew between taps under thermal variation.
Can DS1100LZ-125 drive standard TTL loads directly?
Yes, each tap of the DS1100LZ-125 is rated to drive up to 10 LS-TTL loads, verified under DC and AC conditions per the datasheet. This capability eliminates the need for external buffer stages in legacy TTL interfacing, preserving signal integrity and simplifying board design. The DS1100LZ-125 achieves this while maintaining CMOS-compatible input thresholds and low ICC.
Is DS1100LZ-125 pin-compatible with other DS1100L variants?
Yes, all DS1100LZ-xxx variants-including DS1100LZ-125-share identical 8-pin SOIC pinout, electrical interface, and functional behavior. Only the nominal delay values differ across the family. This allows drop-in replacement during prototyping or production when adjusting delay requirements, provided the new variant meets the same thermal and supply constraints.
What package type does DS1100LZ-125 use, and is it RoHS-compliant?
DS1100LZ-125 uses an 8-pin SOIC package (150-mil width) with RoHS-compliant, lead(Pb)-free construction indicated by the "+" suffix in ordering codes like DS1100LZ-125+. It supports vapor-phase and infrared reflow soldering per JEDEC standards, and its land pattern matches outline no. 21-0041 with footprint 90-0096.
