Product details
Overview
DS1100LZ-250+ from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 50ns, 100ns, 150ns, 200ns, and 250ns across TAP1–TAP5. It operates from 3.0V to 3.6V over –40°C to +85°C, reproduces both leading and trailing edges with ±4ns tolerance at full temperature range, and drives up to 10 LS-TTL loads per tap. It is used in high-speed timing alignment, clock deskewing, and pulse-width adjustment in industrial control and test equipment.
For engineers reviewing the DS1100LZ-250+ datasheet, DS1100LZ-250+ pinout, DS1100LZ-250+ application, or DS1100LZ-250+ equivalent, key selection criteria include tap delay accuracy over temperature, edge fidelity for dual-edge-sensitive logic, SO-8 package compatibility, and TTL/CMOS interface capability without level-shifting.
Technical Context
The DS1100LZ-250+ implements a monolithic all-silicon delay path-no hybrid or RC-based elements-ensuring stable propagation delay independent of aging or humidity. Each of its five taps provides fixed, equally spaced delays derived from a single physical delay chain, with unidirectional drift: if one tap slows with temperature, all slow proportionally.
It uses CMOS input and output stages compatible with TTL logic thresholds (VIH ≥ 2.0V, VIL ≤ 0.8V), supports 1MHz maximum input frequency, and guarantees 2.0ns to 2.5ns output rise/fall times under 74F04-equivalent loading. Power-up time is 200μs, and active supply current is 10mA at 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures compatibility with 3.3V system rails and noise margin against LDO dropout. |
| TAP5 Delay | 250ns nominal (±13% over –40°C to +85°C) - enables precise pulse stretching or synchronization at sub-400MHz timing resolution. |
| Input-to-Tap Delay Tolerance | ±4ns for delays ≤40ns; ±13% for delays >40ns - defines worst-case skew between input and TAP5 in industrial environments. |
| Output Drive Strength | 8mA sink / –1mA source - sufficient to directly drive 10× 74LS loads without buffering. |
| Operating Temperature | –40°C to +85°C - qualified for extended industrial applications including motor drives and automated test equipment. |

Pinout & Package
DS1100LZ-250+ is housed in an 8-pin small-outline (SO) package, 150-mil body width, RoHS-compliant and lead(Pb)-free. Pin 1 is IN, Pin 2 is TAP2, Pin 3 is TAP4, Pin 4 is GND, Pin 5 is TAP5, Pin 6 is TAP3, Pin 7 is TAP1, Pin 8 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Signal Input | Accepts TTL-/CMOS-compatible logic transitions; 5pF input capacitance minimizes reflection and loading on driving gate. |
| TAP1 (Pin 7) | First Delay Output | Delivers input signal delayed by 50ns; same edge fidelity as input-critical for phase-aligned sampling. |
| TAP2 (Pin 2) | Second Delay Output | Delivers 100ns-delayed replica; matches TAP1 skew behavior for multi-point timing calibration. |
| TAP3 (Pin 6) | Third Delay Output | Provides 150ns delay; unidirectional temperature tracking ensures consistent inter-tap spacing across operating range. |
| TAP4 (Pin 3) | Fourth Delay Output | Outputs 200ns-delayed signal; enables four-stage pipeline alignment without external delay compensation. |
| TAP5 (Pin 5) | Fifth Delay Output | Final 250ns tap; specified with ±13% tolerance-supports setup/hold margining in FPGA I/O interfaces. |
| VCC (Pin 8) | Power Supply | +3.3V supply input; requires local 0.1μF ceramic decoupling adjacent to pin for stable AC performance. |
| GND (Pin 4) | Ground Reference | Common return for all I/O and internal delay path; must be low-inductance connection to minimize ground bounce. |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay architecture | Eliminates drift and hysteresis associated with RC or analog delay methods-enables repeatable, production-stable timing. |
| Five equally spaced taps | Enables linear interpolation between delay points and simplifies multi-phase clock generation without external logic. |
| Leading- and trailing-edge accuracy | Ensures matched propagation for both rising and falling edges-required for PWM duty-cycle preservation and bidirectional bus timing. |
| TTL-/CMOS-compatible I/O | Operates directly with 74LS, 74F, and modern 3.3V logic families-no level translators needed in mixed-voltage systems. |
| Vapor-phase and IR solderable | Validated for standard lead-free reflow profiles (up to +260°C), supporting high-yield automated PCB assembly. |
Applications

FAQ
What is the nominal delay value for each tap of the DS1100LZ-250+?
The DS1100LZ-250+ provides five equally spaced nominal delays: TAP1 = 50ns, TAP2 = 100ns, TAP3 = 150ns, TAP4 = 200ns, and TAP5 = 250ns. These values are specified at +25°C and VCC = 3.3V, with tolerance bands that widen over the full –40°C to +85°C operating range. The DS1100LZ-250+ achieves this via a monolithic silicon delay line, ensuring consistent inter-tap spacing and unidirectional drift behavior.
Does the DS1100LZ-250+ support both rising and falling edge delays with equal accuracy?
Yes, the DS1100LZ-250+ is explicitly designed to reproduce both leading and trailing edges with equal precision. Its all-silicon architecture guarantees matched tPLH and tPHL delays across all taps, with initial tolerances of ±2ns at +25°C and ±4ns over –40°C to +85°C for delays ≤40ns. This dual-edge fidelity makes DS1100LZ-250+ suitable for PWM, bidirectional bus timing, and any application where duty cycle integrity matters.
What is the maximum load drive capability per tap on the DS1100LZ-250+?
Each tap of the DS1100LZ-250+ can drive up to 10 LS-TTL loads, corresponding to an output sink current of 8mA and source current of –1mA under minimum VCC (3.0V). This drive strength is verified with 74F04-equivalent loading and ensures reliable fanout without external buffers in most 3.3V logic systems. The DS1100LZ-250+ maintains this capability across its full operating temperature and voltage range.
Is the DS1100LZ-250+ RoHS-compliant and compatible with lead-free reflow?
Yes, the "+" suffix in DS1100LZ-250+ denotes a lead(Pb)-free and RoHS-compliant SO-8 package. It is qualified for vapor-phase and infrared reflow soldering, with a peak reflow temperature of +260°C for lead-free processes. The device meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for standard handling, and its package outline (S8+4) is documented in Maxim's official land pattern library.
Can the DS1100LZ-250+ be used in place of the original DS1100 series?
The DS1100LZ-250+ is the 3.3V variant of the DS1100 family and is not a direct drop-in replacement for 5V DS1100 versions due to different supply voltage requirements (3.0V–3.6V vs. 4.75V–5.25V) and input threshold levels. However, it shares identical pinout, tap structure, and functional behavior with other DS1100L variants. System-level validation is required when migrating from 5V to 3.3V logic domains, but DS1100LZ-250+ maintains full backward compatibility within the DS1100L family.
