Product details
Overview
DS1100M-125 from Maxim Integrated is a 5-tap silicon delay line IC delivering precisely spaced delays of 25ns, 50ns, 75ns, 100ns, and 125ns at each tap, operating at 5V with ±4ns delay tolerance over -40°C to +85°C, and capable of driving up to 10 LS-TTL loads per output - used in digital timing alignment, clock skew correction, and pulse-width adjustment circuits.
For engineers reviewing the DS1100M-125 datasheet, DS1100M-125 pinout, DS1100M-125 application, or DS1100M-125 equivalent, key selection criteria include tap spacing accuracy, edge fidelity for both rising/falling transitions, industrial temperature support, SO-8 or µMAX-8 package compatibility, and TTL/CMOS logic interface robustness.
Technical Context
The DS1100M-125 implements an all-silicon delay architecture with fixed, monotonic delay progression across five equally spaced taps - all delays scale uniformly with temperature and supply voltage, ensuring consistent relative timing relationships. Each tap reproduces both leading and trailing edges with equal precision at the 1.5V threshold level.
It operates exclusively at 5V (4.75V–5.25V), draws ≤50mA active current, and supports standard reflow soldering profiles including lead-free (260°C). Input pulse width must be ≥20% of Tap 5 delay (≥25ns), 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 |
|---|---|---|---|
| DS1000-125 | Hybrid construction; higher temperature drift (±100ppm/°C vs. DS1100M-125's ±30ppm/°C); larger SO-16 footprint | Limited to commercial temp range (-20°C to +70°C); not qualified for industrial control or automotive under-hood use | Select only if legacy hybrid design reuse is required and temperature stability is non-critical |
| MAX9601EUA+ | Single-output, variable-delay IC (1–1000ns); digitally programmable via I²C; 3.3V-only operation | Requires microcontroller interface and firmware; unsuitable for static, hardwired delay configurations | Choose when dynamic delay adjustment or fine-grained resolution (<1ns) is needed - not for fixed-tap applications |
Compared with DS1000-125 and MAX9601EUA+, the DS1100M-125 offers superior industrial-grade stability in a compact 8-pin µMAX package with five pre-calibrated, edge-matched outputs - ideal for cost-sensitive, fixed-delay systems requiring zero software overhead and guaranteed monotonicity.

FAQ
What is the maximum operating temperature range for DS1100M-125?
The DS1100M-125 is rated for continuous operation from -40°C to +85°C, fully specified across this industrial temperature range for delay accuracy, drive strength, and power consumption. All AC and DC parameters - including ±4ns delay tolerance and 12mA output sink capability - are guaranteed within this range, making DS1100M-125 suitable for harsh-environment applications such as motor drives and outdoor telecom equipment.
Does DS1100M-125 support both rising and falling edge delays with equal precision?
Yes, DS1100M-125 is explicitly designed to reproduce both leading and trailing edges with equal precision - measured at the 1.5V threshold level, with identical tPLH and tPHL tolerances (±4ns for taps ≤40ns). This ensures pulse-width integrity across all five outputs, which is essential for applications like gated clock generation and asymmetric waveform shaping where duty cycle preservation matters.
What package type is used for DS1100M-125, and is it RoHS-compliant?
DS1100M-125 uses the 8-pin µMAX package (outline U8+1), a 3mm × 3mm surface-mount package with 0.65mm pitch. The "+" suffix in the ordering code (e.g., DS1100M-125+) confirms RoHS compliance and lead-free finish. This package supports vapor-phase, infrared, and wave soldering, including JEDEC J-STD-020-compliant lead-free reflow up to 260°C.
Can DS1100M-125 drive standard TTL loads directly?
Yes, DS1100M-125 can drive up to 10 LS-TTL loads per tap - verified by its guaranteed 12mA low-level output current (IOL) and -1mA high-level output current (IOH) at VCC = 4.75V. This eliminates the need for external buffer stages in most 5V logic interfacing scenarios, reducing component count and propagation uncertainty in timing-critical paths.
How does DS1100M-125 differ from the DS1000 series in terms of reliability and performance?
DS1100M-125 replaces the older DS1000 series with an all-silicon delay core, eliminating hybrid ceramic substrates that suffer from long-term drift and thermal hysteresis. DS1100M-125 achieves ±4ns delay tolerance over temperature versus ±100ppm/°C drift in DS1000-125, and fits in half the PCB area (8-pin µMAX vs. 16-pin SO). Its improved edge fidelity and industrial temperature rating make DS1100M-125 the preferred choice for new designs.
