Product details
Overview
DS1100LZ-300+ from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 60ns, 120ns, 180ns, 240ns, and 300ns across TAP1–TAP5. It operates from 3.0V to 3.6V over –40°C to +85°C, delivers TTL-/CMOS-compatible outputs, and drives up to 10 × 74LS loads per tap. Used in high-speed timing alignment for test equipment and digital signal synchronization.
For engineers reviewing the DS1100LZ-300+ datasheet, DS1100LZ-300+ pinout, DS1100LZ-300+ application, or DS1100LZ-300+ equivalent, key selection factors include tap delay precision (±4ns for ≤40ns delays, ±13% for >40ns), leading/trailing edge matching, SO-8 package compatibility, and industrial temperature support.
Technical Context
The DS1100LZ-300+ implements an all-silicon delay architecture with five fixed, equally spaced delay taps-no PLL or programmable logic. Each tap reproduces the input logic state after its specified delay, with identical propagation characteristics for rising and falling edges (tPLH = tPHL).
It uses low-power CMOS circuitry, supports 1MHz input frequency, and maintains delay stability across voltage (3.0V–3.6V) and temperature (–40°C to +85°C). Input pulse width must be ≥20% of Tap 5 delay (≥60ns), and output rise/fall time is 2.0–2.5ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures stable operation in 3.3V systems with ±10% rail tolerance |
| TAP5 Delay | 300ns nominal - sets maximum fixed latency for signal alignment in synchronous circuits |
| Delay Tolerance | ±13% over –40°C to +85°C - defines worst-case skew between input and TAP5 under full industrial range |
| Output Drive | 8mA sink / –1mA source - sufficient to drive 10 × 74LS inputs without external buffering |
| Input Capacitance | 5–10pF - minimizes loading on preceding stage and preserves signal integrity at high frequencies |
| Rise/Fall Time | 2.0–2.5ns - enables clean edge reproduction for sub-5ns timing-critical applications |
| Operating Temp | –40°C to +85°C - qualified for industrial-grade embedded and test instrumentation use |
Pinout & Package
DS1100LZ-300+ is housed in an 8-pin SOIC (150-mil) package, RoHS-compliant and lead(Pb)-free, with standard JEDEC SO-8 footprint (outline 21-0041, land pattern 90-0096).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input; accepts TTL/CMOS levels, 5–10pF load |
| 2 | TAP 2 | Second delay output (120ns); fan-out capable of 10 × 74LS loads |
| 3 | TAP 4 | Fourth delay output (240ns); matched edge accuracy with IN |
| 4 | GND | Digital ground reference; requires low-impedance PCB connection |
| 5 | TAP 5 | Fifth delay output (300ns); longest fixed delay tap, ±13% tolerance |
| 6 | TAP 3 | Third delay output (180ns); unidirectionally tracks TAP1–TAP5 delay drift |
| 7 | TAP 1 | First delay output (60ns); lowest-latency tap, ±4ns tolerance at 25°C |
| 8 | VCC | +3.3V supply; bypassing with 0.1µF ceramic capacitor required at pin |

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 |
|---|---|---|---|
| DS1100LZ-250+ | Shorter max delay (250ns vs. 300ns); TAP5 = 250ns, TAP1 = 50ns | Suitable where total system latency budget is ≤250ns | Select when design requires tighter overall delay range and lower power (ICC ~10mA at 1MHz) |
| DS1100LU-300+ | Same delay values, but in 8-pin µMAX (U8+1) package - 3mm × 3mm vs. SO-8's 4.9mm × 6.0mm | Better suited for space-constrained portable or modular designs | Choose for high-density layouts where board area is critical and thermal derating (362mW) is acceptable |
Compared with DS1100LZ-250+ and DS1100LU-300+, the DS1100LZ-300+ offers the longest fixed delay (300ns) in the standard SO-8 footprint, balancing PCB real estate, thermal performance (470.6mW), and industrial temperature compliance without requiring custom layout or reflow profile changes.

FAQ
What is the nominal delay of each tap in DS1100LZ-300+?
The DS1100LZ-300+ provides five equally spaced nominal delays: TAP1 = 60ns, TAP2 = 120ns, TAP3 = 180ns, TAP4 = 240ns, and TAP5 = 300ns. These values are specified at +25°C and VCC = 3.3V, with tolerance scaling by delay magnitude - ±4ns for TAP1–TAP3 and ±13% for TAP4–TAP5 across the full –40°C to +85°C range.
Does DS1100LZ-300+ support both rising and falling edge delays equally?
Yes, DS1100LZ-300+ is explicitly designed for equal leading- and trailing-edge accuracy. Its tPLH (rising delay) and tPHL (falling delay) match within specification across all taps and operating conditions, ensuring no duty-cycle distortion at outputs - a key requirement for clock distribution and pulse shaping applications.
What is the maximum input frequency supported by DS1100LZ-300+?
The DS1100LZ-300+ is characterized for reliable operation up to 1MHz input frequency, with active current ICC = 10mA at that rate. Higher frequencies increase ICC and may degrade delay accuracy due to layout sensitivity and decoupling limitations - the datasheet cautions that near-maximum frequency performance is application-dependent.
Can DS1100LZ-300+ drive standard TTL loads directly?
Yes, DS1100LZ-300+ can drive up to 10 × 74LS loads per tap, verified under standard test conditions (VCC = 3.0V min, VOL = 0.5V, IOL = 8mA). Its TTL-/CMOS-compatible outputs meet VIH ≥ 2.0V and VIL ≤ 0.8V thresholds, enabling direct interfacing with legacy and modern logic families without level-shifting.
Is DS1100LZ-300+ pin-compatible with other DS1100L variants in SO-8?
Yes, all DS1100LZ-xxx+ variants share identical SO-8 (150-mil) pinout and electrical behavior - only nominal delay values differ. The DS1100LZ-300+ uses the same VCC, GND, IN, and TAP1–TAP5 pin assignments as DS1100LZ-200+ or DS1100LZ-500+, allowing drop-in replacement when delay requirements change within the same package.
