Product details
Overview
DS1100LZ-45+T from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 9ns (TAP 1), 18ns (TAP 2), 27ns (TAP 3), 36ns (TAP 4), and 45ns (TAP 5), operating from −40°C to +85°C in an 8-pin SO package. It 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 skew correction.
For engineers reviewing the DS1100LZ-45+T datasheet, DS1100LZ-45+T pinout, DS1100LZ-45+T application, or DS1100LZ-45+T equivalent, key selection criteria include tap delay accuracy (±4ns over full temperature range for ≤40ns delays), 3.3V CMOS/TTL compatibility, low-power operation (10mA typical ICC), and industrial-grade reliability in surface-mount SO packaging.
Technical Context
The DS1100LZ-45+T implements a monolithic all-silicon delay architecture with five fixed, equally spaced taps referenced to a single input. Delay values are calibrated at +25°C and VCC = 3.3V, with unidirectional drift across temperature and supply voltage - all taps slow or speed together, eliminating relative skew between outputs.
Each tap delivers TTL-/CMOS-compatible logic-level outputs with 2.0–2.5ns rise/fall times and guaranteed 1.5V switching threshold measurement points. Input pulse width must be ≥20% of TAP 5 delay (≥9ns), and power-up time is 200μs, enabling use in synchronous reset and clock-edge alignment circuits without external conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures stable operation across industrial 3.3V rail tolerances without regulation. |
| TAP 5 Delay | 45ns nominal - defines maximum fixed propagation latency for timing margining and phase alignment. |
| Delay Tolerance | ±4ns (−40°C to +85°C, ≤40ns taps) - guarantees deterministic inter-tap spacing under worst-case environmental stress. |
| Output Drive | 8mA sink / −1mA source - supports direct interface to 74LS logic without buffering. |
| Input Capacitance | 5–10pF - minimizes loading on preceding driver stage and preserves signal integrity at >100MHz edge rates. |
| Power-Up Time | 200μs - enables reliable initialization after power sequencing without external reset hold-off. |
Pinout & Package
DS1100LZ-45+T is housed in an 8-pin SOIC (150-mil) package with standard JEDEC MS-012AC outline and RoHS-compliant lead-free finish (+T suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input accepting TTL/CMOS levels; referenced to GND, drives all internal taps. |
| 2 | TAP 2 | Second delayed output (18ns); electrically identical to other taps, capable of driving 10× 74LS loads. |
| 3 | TAP 4 | Fourth delayed output (36ns); shares same output structure and timing tolerance as TAP 1–5. |
| 4 | GND | Digital ground reference for all I/O and internal circuitry; requires low-impedance PCB connection. |
| 5 | TAP 5 | Fifth and longest-delay output (45ns); defines system-level timing budget ceiling for skew compensation. |
| 6 | TAP 3 | Third delayed output (27ns); provides mid-range timing point for multi-stage pipeline alignment. |
| 7 | TAP 1 | First delayed output (9ns); shortest fixed latency path for fine-grained delay insertion. |
| 8 | VCC | +3.3V supply input; bypassing with 0.1μF ceramic capacitor near pin is required for AC noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay core | Eliminates hybrid component aging and thermal hysteresis, ensuring long-term delay stability over 10+ years. |
| Equal tap spacing | Fixed 9ns increment between consecutive taps (TAP1→TAP2→…→TAP5) enables predictable interpolation and linear delay stepping. |
| Leading/trailing edge matching | Identical tPLH and tPHL tolerance (±4ns) ensures symmetrical duty-cycle preservation across all taps. |
| Industrial temperature range | Guaranteed operation from −40°C to +85°C supports deployment in automotive engine control, industrial PLC, and outdoor telecom equipment. |
| RoHS-compliant SO package | 8-pin SOIC with lead-free terminations (S8+4 outline) enables compatibility with modern vapor-phase and IR reflow processes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-tap delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1023-50+ | 5-tap, 50ns max delay, 5V-only supply, SO-8 package | Requires 5V rail; lacks 3.3V compatibility and industrial temp grade | Select when legacy 5V systems demand identical tap count and higher max delay (50ns vs. 45ns) |
| MAX5002EPA+ | 3-tap, 3.3V, ±1% delay accuracy, PDIP-8 package | Fewer taps (3 vs. 5); through-hole only; tighter % tolerance but no ns-level absolute spec | Select when board space allows DIP and application needs higher relative precision over smaller delay range |
Compared with DS1100LZ-45+T, DS1023-50+ offers greater maximum delay but mandates 5V operation and lacks industrial temperature support, while MAX5002EPA+ trades tap count and package type for improved relative delay stability - making DS1100LZ-45+T optimal for compact, 3.3V, wide-temp fixed-tap timing.

FAQ
What is the nominal delay value for each tap of the DS1100LZ-45+T?
The DS1100LZ-45+T provides five equally spaced nominal delays: TAP 1 = 9ns, TAP 2 = 18ns, TAP 3 = 27ns, TAP 4 = 36ns, and TAP 5 = 45ns - all specified at +25°C and VCC = 3.3V per Maxim's Table 1. These values are fixed by silicon design and cannot be adjusted. The DS1100LZ-45+T achieves this via monolithic all-silicon delay elements, ensuring consistent tap-to-tap spacing across operating conditions.
Does the DS1100LZ-45+T support both rising and falling edge delay accuracy?
Yes, the DS1100LZ-45+T is explicitly designed to reproduce both leading and trailing edges with equal precision. Its tPLH (rising-edge delay) and tPHL (falling-edge delay) exhibit identical tolerance: ±4ns over −40°C to +85°C for taps ≤40ns. This symmetry ensures duty-cycle integrity in clock distribution and pulse-width preservation in digital signal conditioning applications using the DS1100LZ-45+T.
What is the recommended power supply decoupling for the DS1100LZ-45+T?
A 0.1μF ceramic capacitor placed as close as possible to the VCC (pin 8) and GND (pin 4) terminals is required for stable DS1100LZ-45+T operation. This minimizes high-frequency supply noise coupling into the delay path, which could otherwise induce jitter or delay variation. No bulk capacitance is specified, but the DS1100LZ-45+T's 10mA typical ICC allows standard 3.3V regulator pairing without additional filtering beyond the local 0.1μF.
Can the DS1100LZ-45+T drive standard TTL logic directly?
Yes, each tap of the DS1100LZ-45+T can drive up to 10 74LS loads, confirming direct TTL compatibility. Its IOL = 8mA (sink) and IOH = −1mA (source) meet 74LS input current requirements, and its VOH ≥ 2.3V / VOL ≤ 0.5V at VCC = 3.0V satisfies TTL logic thresholds. This eliminates need for level-shifting buffers when interfacing with legacy 74LS-based systems using the DS1100LZ-45+T.
Is the DS1100LZ-45+T RoHS-compliant and compatible with lead-free reflow?
Yes, the "+T" suffix in DS1100LZ-45+T denotes a lead(Pb)-free, RoHS-compliant SOIC package qualified for vapor-phase and IR reflow soldering. Maxim specifies a peak reflow temperature of +260°C for lead-free processes, matching IPC/JEDEC J-STD-020D. The DS1100LZ-45+T's S8+4 package outline and land pattern (90-0096) are documented for reliable assembly in modern SMT lines.
