Product details
Overview
DS1100Z-25/T&R from Maxim Integrated is a 5-tap silicon delay line providing fixed, equally spaced delays of 5ns, 10ns, 15ns, 20ns, and 25ns at each tap. It operates at 5V, supports -40°C to +85°C industrial temperature range, and reproduces both leading and trailing edges with ±4ns tolerance across full temperature range. It drives up to 10 LS-TTL loads per tap and is used in digital timing alignment, clock skew correction, and pulse-width adjustment circuits.
For engineers reviewing the DS1100Z-25/T&R datasheet, DS1100Z-25/T&R pinout, DS1100Z-25/T&R application, or DS1100Z-25/T&R equivalent, key selection criteria include tap delay precision over temperature, TTL/CMOS compatibility, SO-8 package footprint, low-power CMOS operation, and edge-fidelity requirements for synchronous logic interfacing.
Technical Context
The DS1100Z-25/T&R implements an all-silicon delay architecture with five discrete, monotonic delay paths derived from a single input signal. Each tap delivers identical propagation characteristics for rising and falling edges, with delay variation tightly coupled across taps under voltage or temperature shifts - ensuring consistent inter-tap spacing.
It uses standard CMOS logic-level inputs and outputs, requires no external components, and achieves stable delay performance without trimming or calibration. The device is fully compatible with 5V TTL and CMOS logic families and supports vapor-phase, IR, and wave soldering processes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100U-25/T&R | Same electrical specs but in 8-pin µMAX (3mm × 3mm) package - 60% smaller footprint than SO-8 | Better suited for ultra-compact PCBs where area is constrained; thermal resistance differs slightly | Select DS1100U-25/T&R when board space is premium and reflow profile supports µMAX |
| DS1000S-25+T | Hybrid delay line with wider delay tolerance (±10%) and higher power consumption; obsolete but still available | Limited to commercial temperature range (0°C to +70°C); not rated for industrial use | Choose DS1000S-25+T only if legacy design reuse mandates identical form factor and no industrial qualification needed |
Compared with DS1100U-25/T&R, DS1100Z-25/T&R offers larger pad geometry for easier inspection and rework, while DS1000S-25+T lacks guaranteed edge fidelity and temperature stability - making DS1100Z-25/T&R the preferred choice for new industrial designs requiring precision and reliability.

FAQ
What is the nominal delay value for each tap of the DS1100Z-25/T&R?
The DS1100Z-25/T&R provides five equally spaced delays: TAP 1 = 5ns, TAP 2 = 10ns, TAP 3 = 15ns, TAP 4 = 20ns, and TAP 5 = 25ns. These values are specified at +25°C and 5V, with ±4ns tolerance across the full −40°C to +85°C operating range. Each tap reproduces both rising and falling edges with matched delay characteristics, and all delays scale uniformly with temperature or supply voltage changes.
Is the DS1100Z-25/T&R compatible with 3.3V logic systems?
No, the DS1100Z-25/T&R is designed exclusively for 5V operation (4.75V to 5.25V). Its input thresholds (VIH = 2.2V min, VIL = 0.8V max) and output drive levels are optimized for TTL/CMOS 5V families. Connecting it to a 3.3V system may result in marginal noise margins or undefined switching behavior. For 3.3V applications, consider evaluating newer Maxim or Analog Devices timing solutions explicitly rated for dual-supply or 3.3V operation.
Does the DS1100Z-25/T&R require external decoupling capacitors?
Yes, DS1100Z-25/T&R requires local 0.1μF ceramic decoupling between VCC (Pin 1) and GND (Pin 8), placed within 2mm of the package. This is essential to suppress supply transients induced by simultaneous tap switching, which could otherwise degrade delay accuracy or cause output jitter. The datasheet specifies that measurements were performed with proper decoupling, and omission may increase delay variation beyond the ±4ns specification.
Can the DS1100Z-25/T&R drive more than 10 LS-TTL loads per tap?
No - the DS1100Z-25/T&R is characterized to drive up to 10 LS-TTL loads (each ~20μA input current) per tap while maintaining specified delay accuracy and output voltage levels. Exceeding this load increases propagation delay, reduces noise margin, and may cause output waveform distortion. For heavier loads, buffer amplifiers such as 74AC04 or SN74LVC1G04 should be used between DS1100Z-25/T&R outputs and downstream inputs.
What does the "/T&R" suffix indicate in DS1100Z-25/T&R?
The "/T&R" suffix in DS1100Z-25/T&R stands for Tape and Reel - indicating the device is supplied in EIA-481-compliant carrier tape, optimized for automated surface-mount assembly. This packaging format includes standardized pocket pitch, cover tape sealing, and reel labeling compliant with IPC-7351 standards. DS1100Z-25/T&R is functionally identical to DS1100Z-25 but formatted for high-volume SMT line integration.
