Product details
Overview
DS1100LZ-20+ from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 4ns (TAP 1) through 20ns (TAP 5), ±2ns tolerance at +25°C/3.3V, operating from -40°C to +85°C, and capable of driving 10 × 74LS loads per tap - used in high-speed timing alignment, clock deskew, and pulse-width adjustment circuits.
For engineers reviewing the DS1100LZ-20+ datasheet, DS1100LZ-20+ pinout, DS1100LZ-20+ application, or DS1100LZ-20+ equivalent, key selection criteria include tap delay precision across temperature, TTL/CMOS compatibility, SO-8 package footprint, and guaranteed leading/trailing edge matching for edge-sensitive digital systems.
Technical Context
The DS1100LZ-20+ implements a monolithic all-silicon delay architecture with five fixed, equally spaced delay taps derived from a single input signal. Each tap reproduces both rising and falling edges with matched propagation delay, enabling precise pulse shaping without external compensation.
It operates within a 3.0V–3.6V supply range and delivers sub-nanosecond edge alignment stability over industrial temperature. Delay accuracy is specified as ±2ns (≤40ns taps) or ±5% (>40ns taps), with output rise/fall times ≤2.5ns and power-up time <200μs - critical for synchronous logic initialization and jitter-sensitive sampling paths.
Key Specifications

| 2 | TAP 2 | Second delay output (8ns nominal); reproduces input state with matched rising/falling edge delay. |
| 3 | TAP 4 | Fourth delay output (16ns nominal); electrically isolated from other taps to prevent crosstalk-induced skew. |
| 4 | GND | Analog/digital ground reference; must be low-impedance for stable delay accuracy and noise immunity. |
| 5 | TAP 5 | Fifth delay output (20ns nominal); highest-delay tap, fully characterized for edge fidelity and load drive. |
| 6 | TAP 3 | Third delay output (12ns nominal); center tap used for symmetric delay interpolation or differential timing references. |
| 7 | TAP 1 | First delay output (4ns nominal); shortest delay path, optimized for minimal jitter accumulation. |
| 8 | VCC | +3.3V supply input; requires local 0.1μF ceramic decoupling adjacent to pin for AC performance. |

Use Value: Guarantees <±2ns relative skew between TAP1 and TAP5 outputs, enabling picosecond-level time-difference-of-arrival measurements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-25+ | 5ns–25ns tap delays (vs. 4ns–20ns); same SO-8 package, identical electrical specs except nominal delay values. | Suitable when 5ns minimum delay step is acceptable and 25ns maximum delay is required instead of 20ns. | Select DS1100LZ-25+ only if system timing budget requires longer maximum delay; otherwise DS1100LZ-20+ provides tighter resolution at lower delay range. |
| MAX9602ASA+ | Single-output, programmable 0.5ns–10ns delay with digital control; SO-8 package but different pinout and SPI interface required. | Used where dynamic delay adjustment is needed, not fixed-tap timing; lacks multi-tap parallel output capability. | Choose MAX9602ASA+ only for reconfigurable delay paths; DS1100LZ-20+ remains optimal for static, multi-point timing distribution. |
Compared with DS1100LZ-25+, DS1100LZ-20+ offers finer 4ns minimum delay for ultra-low-skew applications; compared with MAX9602ASA+, it delivers simultaneous 5-tap outputs without control overhead - making DS1100LZ-20+ ideal for fixed, parallel timing alignment tasks.

FAQ
What is the nominal delay value for each tap of the DS1100LZ-20+?
The DS1100LZ-20+ provides five equally spaced nominal delays: TAP 1 = 4ns, TAP 2 = 8ns, TAP 3 = 12ns, TAP 4 = 16ns, and TAP 5 = 20ns. These values are measured at +25°C and VCC = 3.3V, with ±2ns tolerance for all taps. The DS1100LZ-20+ is characterized across the full -40°C to +85°C range, maintaining tight delay matching between rising and falling edges at each tap.
Does the DS1100LZ-20+ support both TTL and CMOS logic levels?
Yes, the DS1100LZ-20+ features TTL- and CMOS-compatible inputs and outputs. Its VIH threshold is ≥2.0V and VIL is ≤0.8V, allowing direct interface with standard 3.3V logic families. Each tap can drive up to 10 × 74LS loads, and output voltage levels meet TTL swing requirements under specified load conditions. The DS1100LZ-20+ does not require level-shifting circuitry in mixed-logic systems.
What package type and RoHS status does the DS1100LZ-20+ use?
The DS1100LZ-20+ is supplied in an 8-pin SO (Small Outline) package with 150-mil width and is RoHS-compliant and lead(Pb)-free, indicated by the "+" suffix. It supports vapor-phase and IR reflow soldering up to +260°C. The land pattern matches standard SO-8 footprints, and the DS1100LZ-20+ shares mechanical compatibility with other DS1100LZ variants in the same package family.
How does temperature affect delay accuracy in the DS1100LZ-20+?
Over the full -40°C to +85°C operating range, the DS1100LZ-20+ exhibits delay variation of ±4ns for taps ≤40ns (i.e., all five taps). This tolerance is unidirectional - all taps slow down or speed up together with temperature change, preserving relative spacing. The DS1100LZ-20+ is fully characterized and guaranteed across this range, with no additional derating required for industrial applications.
Can the DS1100LZ-20+ drive heavy capacitive loads without signal degradation?
The DS1100LZ-20+ is rated to drive up to 10 × 74LS loads per tap, corresponding to ~100pF typical capacitive load. Its output rise/fall times remain ≤2.5ns under these conditions. For heavier loads, external buffer amplifiers are recommended to maintain edge fidelity and delay accuracy. Layout best practices - including short traces, ground plane proximity, and local decoupling - are essential to preserve the DS1100LZ-20+'s specified timing performance.
