Product details
Overview
DS1100LZ-20+T 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 I/O, 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 datasheet, DS1100LZ-20+T pinout, DS1100LZ-20+T application, or DS1100LZ-20+T equivalent, key selection criteria include fixed low-jitter tap delays, 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 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, equally spaced delays derived from a single input signal without internal clocking or PLL circuitry.
Delay accuracy is specified as ±2ns (for ≤40ns delays) at +25°C/3.3V and widens to ±4ns over full temperature range; output rise/fall time is 2.0–2.5ns, and power-up time is 200μs. Input pulse width must be ≥20% of TAP 5 delay (i.e., ≥4ns), and outputs are tested at 1.5V switching threshold under 74F04-equivalent loading.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures compatibility with 3.3V logic systems and robustness against rail variation |
| Nominal Tap Delays | TAP1=4ns, TAP2=8ns, TAP3=12ns, TAP4=16ns, TAP5=20ns - fixed, equally spaced delays for precise pulse alignment |
| Delay Tolerance | ±2ns at +25°C/3.3V (≤40ns delays) - enables sub-nanosecond edge placement control in high-speed digital timing |
| Output Drive | 8mA sink / -1mA source - sufficient to directly drive 10× 74LS loads without buffering |
| Rise/Fall Time | 2.0–2.5ns - preserves signal integrity for >200MHz pulse applications |
| Operating Temp | -40°C to +85°C - qualified for industrial-grade embedded and instrumentation environments |
Pinout & Package
DS1100LZ-20+T is housed in an 8-pin SOIC package (150-mil width, outline S8+4), RoHS-compliant and lead(Pb)-free, with standard JEDEC SO-8 footprint (land pattern 90-0096).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input accepting TTL/CMOS levels; triggers all five delay taps synchronously |
| 2 | TAP 2 | Second delay output (8ns); CMOS/TTL-compatible, 1.5V switching threshold |
| 3 | TAP 4 | Fourth delay output (16ns); identical electrical specs to TAP 2 and TAP 1–5 |
| 4 | GND | Digital ground reference for all I/O and internal delay circuitry |
| 5 | TAP 5 | Fifth delay output (20ns); maximum delay tap, used for coarse timing alignment |
| 6 | TAP 3 | Third delay output (12ns); center tap enabling symmetric delay interpolation |
| 7 | TAP 1 | First delay output (4ns); shortest delay for fine-grained edge positioning |
| 8 | VCC | +3.3V supply; must be decoupled locally due to fast edge transitions |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay path | Eliminates aging, thermal drift, and reliability issues associated with hybrid or LC-based delay lines |
| Equal-edge precision | Simultaneous leading- and trailing-edge delay matching ensures pulse width preservation across all taps |
| 5-tap parallel output | Enables multi-point sampling of a single event without cascading or external fanout logic |
| Low-power CMOS | 10mA active current at 1MHz allows integration into power-constrained industrial controllers |

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+T | 5V supply (4.5V–5.5V), same tap spacing and tolerance, higher ICC (15mA) | Requires 5V rail; unsuitable for mixed 3.3V/5V systems without level shifting | Select when legacy 5V logic domains dominate and DS1100LZ-20+T's 3.3V operation is incompatible |
| MAX5032AESA+ | Programmable 1–255ns delay in 1ns steps, SPI interface, 3.3V supply, but single output only | Lacks parallel taps; requires firmware control and adds latency for configuration | Select when variable delay and fine resolution outweigh need for simultaneous multi-tap outputs |
Compared with DS1100LZ-20+T, DS1000LZ-20+T supports higher-voltage logic but increases system power and complicates rail management, while MAX5032AESA+ trades fixed-tap simplicity for programmability and single-output constraint-neither offers pin-compatible replacement nor identical multi-tap functionality.

FAQ
What is the maximum operating frequency supported by the DS1100LZ-20+T?
The DS1100LZ-20+T does not specify a maximum operating frequency; instead, it defines minimum input pulse width (tWI) as 20% of TAP 5 delay (≥4ns for DS1100LZ-20+T). At 1MHz, active current is 10mA. Higher frequencies increase ICC and may degrade delay accuracy due to layout sensitivity and decoupling limitations-designers should verify timing margins at target frequency using the device's 2.0–2.5ns rise/fall times and ±4ns full-range delay tolerance.
Does the DS1100LZ-20+T require external bypass capacitors?
Yes, DS1100LZ-20+T requires local VCC bypassing: a 0.1μF ceramic capacitor placed as close as possible to pin 8 (VCC) and pin 4 (GND) is mandatory to suppress supply transients caused by simultaneous 2.5ns edge transitions across five outputs. Failure to implement proper decoupling risks increased delay variation and output ringing, especially under 10× 74LS load conditions.
Can the DS1100LZ-20+T reproduce pulse width accurately across all taps?
Yes, DS1100LZ-20+T is explicitly designed for equal leading- and trailing-edge delay precision. Both tPLH and tPHL are specified with identical tolerances (±2ns at +25°C), ensuring output pulse width matches input pulse width within measurement uncertainty. This behavior is confirmed in the datasheet's timing diagram and terminology section, where tPLH and tPHL definitions apply uniformly to all taps.
Is the DS1100LZ-20+T pin-compatible with other DS1100L variants like DS1100LZ-50+T?
Yes, all DS1100LZ-xxx+T variants share identical 8-pin SO packaging, pin assignment (IN, TAP1–TAP5, VCC, GND), and DC/AC electrical interface. Only nominal delay values differ across the family; TAP1–TAP5 output timing scales linearly with the suffix (e.g., DS1100LZ-50+T = 10ns/20ns/30ns/40ns/50ns), preserving functional and physical compatibility across replacements.
What is the meaning of the "+T" suffix in DS1100LZ-20+T?
The "+T" suffix in DS1100LZ-20+T indicates tape-and-reel packaging (per Maxim's ordering information table) and RoHS-compliant, lead(Pb)-free construction ("+"). It denotes that the device ships in standard 8mm tape format compatible with automated SMT placement equipment and meets EU RoHS Directive 2011/65/EU requirements for hazardous substances.
