Product details
Overview
DS1100LZ-20/T+MOT from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 4ns (TAP 1) to 20ns (TAP 5), ±2ns input-to-tap delay tolerance at +25°C/3.3V, TTL-/CMOS-compatible inputs/outputs, and operation over -40°C to +85°C. It reproduces both leading and trailing edges with equal precision and drives up to 10 74LS loads per tap in an 8-pin SO package.
For engineers reviewing the DS1100LZ-20/T+MOT datasheet, DS1100LZ-20/T+MOT pinout, DS1100LZ-20/T+MOT application, or DS1100LZ-20/T+MOT equivalent, key selection factors include fixed low-jitter tap spacing, edge-fidelity timing for pulse shaping, industrial temperature range support, and SO-8 surface-mount compatibility with vapor-phase and IR reflow soldering.
Technical Context
The DS1100LZ-20/T+MOT 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 deterministic, fixed delays with matched rise/fall time (2.0–2.5ns) and identical leading/trailing edge accuracy.
It operates as a passive timing element: input logic state is replicated at each tap after a precise, factory-trimmed delay; no internal clock, PLL, or control interface is present. All outputs are CMOS/TTL-compatible with 8mA sink and -1mA source capability under minimum VCC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures stable delay performance within standard 3.3V system rails without regulation overhead |
| Nominal Tap Delays | TAP1=4ns, TAP2=8ns, TAP3=12ns, TAP4=16ns, TAP5=20ns - enables precise multi-stage pulse alignment in high-speed digital systems |
| Delay Tolerance | ±2ns (≤40ns delays, +25°C/3.3V) - guarantees sub-nanosecond repeatability for critical edge-triggered sampling |
| Output Drive | 8mA sink / -1mA source - directly interfaces with 74LS logic without external buffers |
| Rise/Fall Time | 2.0ns to 2.5ns - preserves signal integrity for >200MHz pulse applications |
| Operating Temp | -40°C to +85°C - qualified for industrial-grade embedded timing in harsh environments |
Pinout & Package
DS1100LZ-20/T+MOT is housed in an 8-pin SOIC (150-mil) package with gull-wing leads, RoHS-compliant and compatible with standard vapor-phase and IR reflow processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Digital input signal source; accepts TTL/CMOS logic levels (VIH ≥ 2.0V, VIL ≤ 0.8V) |
| 2 | TAP 2 | Second delayed output (8ns nominal); fan-out capable of driving 10× 74LS loads |
| 3 | TAP 4 | Fourth delayed output (16ns nominal); electrically identical to other taps in drive strength and timing accuracy |
| 4 | GND | Analog/digital ground reference; must be low-impedance for delay stability |
| 5 | TAP 5 | Fifth delayed output (20ns nominal); matches TAP1–TAP4 in edge fidelity and load drive |
| 6 | TAP 3 | Third delayed output (12ns nominal); delay variation tracks unidirectionally with temperature/voltage changes |
| 7 | TAP 1 | First delayed output (4ns nominal); shortest fixed delay path with same ±2ns tolerance as full set |
| 8 | VCC | +3.3V supply; decoupling capacitor required near pin for noise immunity and power-up time <200μs |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1000LZ-20+ | 5V supply (4.5V–5.5V); same 4–20ns tap spacing; ±3% delay tolerance (vs. ±2ns absolute for DS1100LZ-20/T+MOT) | Requires 5V rail; less precise for sub-5ns edge alignment tasks | Select when legacy 5V systems dominate and absolute delay tolerance >±2ns is acceptable |
| MAX5033AESA+ | Single-output 20ns delay only; no multi-tap capability; ±1.5ns tolerance; 3.3V operation | Lacks TAP1–TAP4 flexibility; suited only for single-point delay insertion | Select when only one fixed delay is needed and board space is constrained (8-pin SO vs. 8-pin SO) |
Compared with DS1100LZ-20/T+MOT, DS1000LZ-20+ trades voltage compatibility for reduced delay precision, while MAX5033AESA+ sacrifices tap flexibility for tighter single-delay tolerance-making DS1100LZ-20/T+MOT optimal for multi-point, edge-critical 3.3V timing.

FAQ
What is the maximum operating frequency supported by DS1100LZ-20/T+MOT?
The DS1100LZ-20/T+MOT does not specify a maximum operating frequency but defines input pulse width (tWI) and period requirements. At 1MHz input frequency, active current (ICC) is 10mA. Higher frequencies increase ICC and may affect delay accuracy due to layout sensitivity and decoupling-designs should verify timing margins empirically at target frequency. DS1100LZ-20/T+MOT remains functional beyond 1MHz if pulse width and edge rates meet datasheet limits (e.g., tWI ≥ 500ns, rise/fall ≤ 3.0ns).
Does DS1100LZ-20/T+MOT require external configuration or programming?
No, DS1100LZ-20/T+MOT is a fully passive, unprogrammable silicon delay line. Its five tap delays (4ns, 8ns, 12ns, 16ns, 20ns) are factory-trimmed and fixed. No configuration pins, serial interface, or external components are needed-only VCC, GND, IN, and desired TAPx outputs must be connected. DS1100LZ-20/T+MOT delivers immediate, deterministic delay upon power-up with no initialization sequence.
Can DS1100LZ-20/T+MOT drive 74ACT logic loads?
Yes, DS1100LZ-20/T+MOT can drive 74ACT loads. Its output drive capability (8mA sink, -1mA source at minimum VCC) exceeds the 74ACT input requirements (IIL ≤ -1mA, IIH ≤ 20μA). The DS1100LZ-20/T+MOT's TTL-/CMOS-compatible outputs maintain valid VOH/VOL levels across the full 3.0V–3.6V supply range, ensuring reliable interfacing with 74ACT, 74HC, and 74LS families without level shifters.
What is the power-up time specification for DS1100LZ-20/T+MOT?
The DS1100LZ-20/T+MOT has a specified power-up time (tPU) of 200μs-defined as the maximum time from VCC reaching 3.0V to stable output behavior. During this interval, outputs may be undefined. To ensure deterministic operation, system design must allow ≥200μs after VCC stabilization before applying input signals. This parameter is guaranteed across -40°C to +85°C and applies to DS1100LZ-20/T+MOT in both SO and µMAX packages.
Is DS1100LZ-20/T+MOT pin-compatible with other DS1100L variants like DS1100LZ-50/T+MOT?
Yes, all DS1100LZ-xxx variants-including DS1100LZ-20/T+MOT-are pin-compatible within the SO-8 package. Pin 1 (IN), pins 2/3/5/6/7 (TAP1–TAP5), pin 4 (GND), and pin 8 (VCC) retain identical assignment and electrical behavior across the family. Delay values differ only in internal trimming; no PCB layout change is required when substituting DS1100LZ-20/T+MOT with another DS1100LZ-xxx variant in the same package.
