Product details
Overview
DS1100LZ-40/T&R from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal tap delays of 8ns, 16ns, 24ns, 32ns, and 40ns. It operates from 3.0V to 3.6V over -40°C to +85°C, reproduces both leading and trailing edges with equal precision, and drives up to 10 74LS loads per tap. Used in high-speed timing alignment and signal deskew applications on industrial PCBs.
For engineers reviewing the DS1100LZ-40/T&R datasheet, DS1100LZ-40/T&R pinout, DS1100LZ-40/T&R application, or DS1100LZ-40/T&R equivalent, key selection considerations include tap delay accuracy (±4ns over full temperature range), SO-8 package compatibility, TTL/CMOS input/output compatibility, and 3.3V supply operation without level translation.
Technical Context
The DS1100LZ-40/T&R implements an all-silicon delay architecture with five fixed, equally spaced delay taps derived from a monolithic CMOS delay chain. Each tap delivers deterministic propagation delay referenced to the 1.5V logic threshold, with matched tPLH and tPHL for edge fidelity.
It supports stable operation across commercial and industrial temperature ranges (-40°C to +85°C) with supply voltage tolerance from 3.0V to 3.6V. Input pulse width must be ≥20% of Tap 5 delay (≥8ns), and output rise/fall time is specified at 2.0–2.5ns under defined test load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - Enables direct interface with 3.3V logic families without regulation overhead. |
| Nominal Tap Delays | 8ns / 16ns / 24ns / 32ns / 40ns - Fixed, equally spaced delays for precise multi-point signal timing alignment. |
| Delay Tolerance | ±4ns (≤40ns taps, -40°C to +85°C) - Guarantees worst-case skew control in industrial environments. |
| Output Drive | 8mA sink / -1mA source - Sufficient to drive 10x 74LS loads without external buffering. |
| Input Compatibility | TTL- and CMOS-compatible - Accepts 0.8V/2.0V logic thresholds; no level-shifter required for mixed-voltage systems. |
| Rise/Fall Time | 2.0–2.5ns - Ensures minimal added jitter and preserves signal integrity in >100MHz clock/data paths. |
Pinout & Package
DS1100LZ-40/T&R is housed in an 8-pin SOIC package (150-mil width, outline 21-0041), RoHS-compliant and tape-and-reel packaged for automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended digital input; accepts TTL/CMOS logic levels; referenced to VCC/GND. |
| 2 | TAP 2 | Second delay tap output; delivers input signal delayed by 16ns (nominal). |
| 3 | TAP 4 | Fourth delay tap output; delivers input signal delayed by 32ns (nominal). |
| 4 | GND | Digital ground reference; must be low-impedance connection to minimize noise coupling. |
| 5 | TAP 5 | Fifth delay tap output; delivers input signal delayed by 40ns (nominal); highest delay point. |
| 6 | TAP 3 | Third delay tap output; delivers input signal delayed by 24ns (nominal). |
| 7 | TAP 1 | First delay tap output; delivers input signal delayed by 8ns (nominal); lowest latency tap. |
| 8 | VCC | +3.3V supply; requires local 0.1µF ceramic decoupling adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates hybrid or ceramic delay line reliability risks and enables full CMOS process traceability and wafer-level testing. |
| Equal-precision leading/trailing edge delay | Ensures symmetrical pulse-width preservation across all taps-critical for clock distribution and data strobe alignment. |
| Five fixed, equally spaced taps | Provides deterministic, non-programmable delay points ideal for production-critical timing calibration without configuration overhead. |
| SO-8 surface-mount packaging | Reduces PCB footprint vs. DIP; compatible with standard reflow profiles including lead-free (260°C peak). |
| Industrial temperature range support | Validated operation from -40°C to +85°C ensures robustness in factory automation, motor control, and outdoor embedded systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1023-40+T | 5-tap, 5V-only operation (4.75–5.25V); ±5% delay tolerance (not ±ns); SO-8 package. | Requires level translation when used with 3.3V systems; less precise for sub-10ns alignment tasks. | Select DS1023-40+T only if legacy 5V infrastructure exists and ±2ns absolute delay accuracy is not required. |
| MAX9602EUA+ | Programmable 8-tap delay (1–100ns in 1ns steps); 3.3V operation; µMAX-8 package; higher ICC (15mA typical). | Supports dynamic delay adjustment via SPI; adds firmware dependency and layout complexity for static delay needs. | Choose MAX9602EUA+ only when field-updatable delay values or finer resolution (<8ns steps) are mandatory. |
Compared with DS1023-40+T and MAX9602EUA+, the DS1100LZ-40/T&R offers superior fixed-delay precision at 3.3V with zero configuration overhead-ideal for cost-sensitive, high-volume industrial timing where deterministic, unchanging delays are required.

FAQ
What is the maximum operating frequency supported by the DS1100LZ-40/T&R?
The DS1100LZ-40/T&R does not specify a maximum operating frequency but defines minimum input pulse width as 20% of Tap 5 delay (≥8ns), implying reliable operation up to ~62.5MHz (1/16ns period). At higher frequencies, delay accuracy degrades due to layout sensitivity and decoupling-verified in the datasheet's AC Electrical Characteristics section. DS1100LZ-40/T&R performance remains stable up to 1MHz with guaranteed ICC = 10mA.
Does the DS1100LZ-40/T&R require external passive components for basic operation?
No, the DS1100LZ-40/T&R requires only a single 0.1µF ceramic decoupling capacitor between VCC and GND, placed adjacent to pins 8 and 4. No pull-up/pull-down resistors, termination networks, or timing-setting components are needed-its delay values are factory-trimmed and fixed. This simplifies layout and reduces BOM count compared to RC or programmable alternatives.
How does temperature affect the delay accuracy of the DS1100LZ-40/T&R?
Over -40°C to +85°C, DS1100LZ-40/T&R exhibits ±4ns absolute delay tolerance for taps ≤40ns (including all taps of this variant), as specified in the AC Electrical Characteristics table. All taps track unidirectionally with temperature-e.g., if Tap 1 slows, all others slow proportionally-ensuring consistent inter-tap spacing. This behavior is confirmed in Note 3 of the datasheet.
Is the DS1100LZ-40/T&R pin-compatible with other DS1100L variants in SO-8 packages?
Yes, all DS1100LZ-xxx variants-including DS1100LZ-40/T&R-share identical SO-8 pinout, electrical interface, and DC/AC specifications except for nominal delay values. Pin 1 is always IN, pins 2/3/5/6/7 are TAP 2/TAP 4/TAP 5/TAP 3/TAP 1 respectively, and pins 4/8 are GND/VCC. No PCB redesign is needed when substituting within the DS1100LZ family.
Can the DS1100LZ-40/T&R drive modern CMOS loads such as 74LVC or ARM GPIOs directly?
Yes, DS1100LZ-40/T&R outputs meet TTL/CMOS voltage thresholds (VIH ≥2.0V, VIL ≤0.8V) and provide 8mA sink / -1mA source drive-sufficient for 74LVC (IIL ≤±20µA) and most ARM GPIOs (typically ±4mA). No series termination or level shifting is required. Drive capability is verified under open-load conditions per datasheet Note 6.
