Product details
Overview
DS1100LZ-25 from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 5ns (TAP 1), 10ns (TAP 2), 15ns (TAP 3), 20ns (TAP 4), and 25ns (TAP 5), operating over -40°C to +85°C, driving up to 10 × 74LS loads per tap, and designed for precise edge-aligned timing in high-speed digital systems.
For engineers reviewing the DS1100LZ-25 datasheet, DS1100LZ-25 pinout, DS1100LZ-25 application, or DS1100LZ-25 equivalent, key selection considerations include tap-specific delay tolerance (±2ns at +25°C for ≤40ns delays), TTL/CMOS compatibility, SO-8 package footprint, and industrial temperature range support.
Technical Context
The DS1100LZ-25 implements an all-silicon delay architecture with five fixed, equally spaced taps-no PLL, oscillator, or programmable logic. Each tap reproduces both leading and trailing edges with equal precision at the specified delay, referenced to the 1.5V switching threshold.
Delay accuracy is characterized across voltage (3.0V–3.6V) and temperature (-40°C to +85°C), with unidirectional drift: all taps slow or speed together under varying conditions. Input pulse width must exceed 20% of TAP 5 delay (≥5ns), and output rise/fall time is 2.0–2.5ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures stable operation in 3.3V rail systems with ±0.3V margin |
| Nominal Delays (TAP 1–5) | 5ns / 10ns / 15ns / 20ns / 25ns - fixed, factory-trimmed delays enabling deterministic signal alignment |
| Delay Tolerance (≤40ns) | ±2ns at +25°C - guarantees sub-nanosecond edge placement accuracy for critical setup/hold windows |
| Output Drive Strength | 8mA sink / -1mA source - supports direct interfacing to 74LS logic without external buffers |
| Operating Temperature | -40°C to +85°C - validated for industrial-grade embedded and communications equipment |
| Input Capacitance | 5–10pF - minimizes loading on high-speed clock or data lines |
| Rise/Fall Time | 2.0–2.5ns - preserves signal integrity for >200MHz edge rates |
Pinout & Package
DS1100LZ-25 is housed in an 8-pin SO (150-mil) surface-mount package, compatible with standard reflow soldering processes including lead-free vapor-phase and IR profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Digital input signal source - accepts TTL/CMOS-compatible logic levels (VIH ≥ 2.0V, VIL ≤ 0.8V) |
| 2 | TAP 2 | Second delay output - delivers input signal delayed by 10ns with matched edge fidelity |
| 3 | TAP 4 | Fourth delay output - delivers input signal delayed by 20ns, fully characterized for industrial temp range |
| 4 | GND | Analog/digital ground reference - requires low-impedance PCB connection to minimize jitter |
| 5 | TAP 5 | Fifth delay output - provides 25ns delay, used for maximum skew compensation or timing margin verification |
| 6 | TAP 3 | Third delay output - delivers 15ns delay, central tap for symmetric delay interpolation |
| 7 | TAP 1 | First delay output - provides shortest 5ns delay for fine-grained timing adjustment |
| 8 | VCC | +3.3V supply - must be decoupled with ≥0.1µF ceramic capacitor near pin for AC stability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-20 | Shorter max delay (20ns vs. 25ns); TAP 5 = 20ns instead of 25ns | Suitable where 5ns less total delay is acceptable; tighter delay spacing (4ns steps) | Select when system timing budget allows reduced maximum skew compensation |
| DS1100LZ-30 | Longer max delay (30ns vs. 25ns); TAP 5 = 30ns; wider tap spacing (6ns steps) | Better suited for larger PCB trace mismatches or slower edge rates where coarser delay resolution is acceptable | Choose when longer absolute delay is required and 5ns granularity is not critical |
Compared with DS1100LZ-25, DS1100LZ-20 offers finer 4ns tap spacing but sacrifices 5ns of maximum delay, while DS1100LZ-30 extends the delay range by 5ns at the cost of coarser 6ns step resolution-both share identical SO-8 packaging, drive strength, and temperature rating.

FAQ
What is the nominal delay of each tap in DS1100LZ-25?
The DS1100LZ-25 provides five fixed delays: TAP 1 = 5ns, TAP 2 = 10ns, TAP 3 = 15ns, TAP 4 = 20ns, and TAP 5 = 25ns - all measured at the 1.5V switching threshold under VCC = 3.3V and +25°C. These values are factory-trimmed and guaranteed across the full industrial temperature range (-40°C to +85°C).
Is DS1100LZ-25 compatible with 5V logic interfaces?
DS1100LZ-25 is a 3.3V device with TTL-/CMOS-compatible inputs (VIH ≥ 2.0V, VIL ≤ 0.8V), allowing direct connection to 5V TTL outputs. However, its outputs swing only to VCC (3.3V), so interfacing with true 5V CMOS inputs may require level translation unless those inputs specify VIH ≤ 2.0V.
Does DS1100LZ-25 require external decoupling capacitors?
Yes - DS1100LZ-25 requires a minimum 0.1µF ceramic decoupling capacitor placed as close as possible to the VCC pin (Pin 8) and GND (Pin 4). This is essential to suppress supply noise and maintain delay accuracy, especially during fast edge transitions that draw transient current.
Can DS1100LZ-25 drive more than 10 × 74LS loads per tap?
No - DS1100LZ-25 is rated to drive up to 10 × 74LS loads per tap (IOL = 8mA, IOH = -1mA). Exceeding this load increases output rise/fall times, degrades delay accuracy, and may cause output voltage violations. For heavier loads, buffer amplification is required before connecting additional gates.
What is the power-up time specification for DS1100LZ-25?
The DS1100LZ-25 has a maximum power-up time (tPU) of 200μs - the time required after VCC reaches 3.0V for the device to achieve stable delay behavior. During this interval, output timing is undefined; system logic should wait ≥200μs after power stabilization before relying on DS1100LZ-25 outputs.
