Product details
Overview
DS1100Z-250/T&R from Maxim Integrated is a 5-tap silicon delay line providing precisely spaced 50ns, 100ns, 150ns, 200ns, and 250ns delays at 5V operation, designed for edge-aligned timing control in digital logic systems, with TTL/CMOS-compatible I/O and ability to drive up to 10 × 74LS loads per tap.
For engineers reviewing the DS1100Z-250/T&R datasheet, DS1100Z-250/T&R pinout, DS1100Z-250/T&R application, or DS1100Z-250/T&R equivalent, key selection considerations include tap delay accuracy (±4ns over –40°C to +85°C), leading/trailing-edge matching, SO-8 package compatibility, and industrial-temperature support without derating.
Technical Context
The DS1100Z-250/T&R implements a monolithic all-silicon delay architecture with five fixed, equally spaced output taps referenced to a single input signal. Each tap reproduces both rising and falling edges with matched propagation delay tolerance, enabling precise skew management in clock distribution, pulse shaping, and timing alignment circuits.
It operates exclusively at 5V (4.75V–5.25V), draws ≤50mA active current, and maintains delay stability across –40°C to +85°C with ±4ns absolute tolerance for delays ≤40ns and ±13% for delays >40ns - here, the 250ns nominal delay falls under the percentage-based tolerance specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Delay (TAP 5) | 250ns - fixed, factory-trimmed delay from IN to TAP 5 output |
| Tap Spacing | 50ns - uniform interval between consecutive taps (TAP1=50ns, TAP2=100ns, etc.) |
| Supply Voltage | 5.0V ±5% - requires stable 5V rail; no internal regulation |
| Delay Tolerance | ±13% over –40°C to +85°C - applies to 250ns nominal delay (±32.5ns) |
| Output Drive | 12mA sink / –1mA source - sufficient for 10 × 74LS loads per tap |
| Input Capacitance | 5–10pF - low loading enables use with high-speed logic without signal degradation |
| Operating Temperature | –40°C to +85°C - fully specified industrial-grade performance |
Pinout & Package
DS1100Z-250/T&R is housed in an 8-pin SOIC package (150 mils wide, outline S8+4), surface-mount compatible with vapor-phase, IR, and wave soldering processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | +5V power supply connection; decoupling capacitor required near pin |
| 2 | TAP 1 | First delayed output (50ns); CMOS/TTL-compatible, 12mA sink capable |
| 3 | TAP 3 | Third delayed output (150ns); identical electrical specs to TAP 1 and TAP 2 |
| 4 | TAP 5 | Fifth delayed output (250ns); matches nominal part-number delay value |
| 5 | IN | Single-ended logic input; accepts 0V/3V TTL-level or CMOS-level signals |
| 6 | TAP 2 | Second delayed output (100ns); unidirectionally tracks TAP 1–TAP 5 delay variation |
| 7 | TAP 4 | Fourth delayed output (200ns); same rise/fall edge precision as all taps |
| 8 | GND | Digital ground reference; must be low-impedance return path for all I/O and VCC |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates hybrid ceramic delay modules; improves long-term reliability and thermal stability |
| Equal tap spacing | Enables predictable, linear interpolation between taps for custom delay synthesis |
| Leading- and trailing-edge matching | Ensures symmetrical pulse width preservation across all five outputs |
| TTL/CMOS compatibility | Direct interface with 74LS, 74F, and standard CMOS families without level-shifting |
| Industrial temperature range | Full AC/DC specifications guaranteed from –40°C to +85°C without derating |
Applications
| Digital Pulse Width Modulation | Logic Skew Compensation |
|---|---|
Use Scenario: Generating variable-width pulses by XOR-ing delayed and undelayed versions of a clock or enable signal. IC Role / Device Role / Timing Role: Provides deterministic, temperature-stable 50ns–250ns delays to create controllable dead time or duty-cycle adjustment. Use Value: Enables precise PWM resolution down to 50ns steps using only one DS1100Z-250/T&R and basic gates - no microcontroller or PLL required. | Use Scenario: Aligning arrival times of multiple clock or strobe signals across PCB traces of unequal length. IC Role / Device Role / Timing Role: Introduces calibrated, matched delays on faster paths to equalize total propagation latency. Use Value: Reduces setup/hold violations in synchronous bus interfaces (e.g., memory controllers) by compensating trace skew up to 250ns. |
| Glitch-Free State Machine Control | Serial Data Sampling Windowing |
Use Scenario: Debouncing asynchronous control inputs (e.g., reset, interrupt) before feeding into synchronous logic. IC Role / Device Role / Timing Role: Delays both edges identically to suppress sub-250ns glitches while preserving valid state transitions. Use Value: Prevents metastability in FPGA or ASIC register stages without adding complex synchronizer chains. | Use Scenario: Creating narrow sampling windows aligned to mid-bit periods in low-jitter serial links (e.g., UART, SPI). IC Role / Device Role / Timing Role: Generates tightly spaced strobes (e.g., TAP1–TAP2 = 50ns) to gate sample latches. Use Value: Improves noise margin during data capture by limiting sampling duration to <100ns, rejecting intersymbol interference. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1000Z-250 | Hybrid ceramic delay; larger SO-16 package; ±10% delay tolerance; higher power consumption | Limited to commercial temperature range (0°C to +70°C); not rated for industrial environments | Select only if legacy board reuse mandates SO-16 footprint and ambient stays within 0°C–70°C |
| MAX9601EUA+ | Programmable 8-tap delay IC; SPI-configurable; 1.6ns–32.8μs range; 3.3V/5V dual-supply | Requires external configuration; higher BOM count; supports dynamic delay adjustment | Choose when variable or multi-mode delay is needed - DS1100Z-250/T&R remains optimal for fixed, low-cost, single-delay-path use. |
Compared with DS1000Z-250 and MAX9601EUA+, the DS1100Z-250/T&R delivers superior temperature stability (–40°C to +85°C), smaller SO-8 footprint, lower cost, and zero configuration overhead - making it ideal for static, high-reliability delay insertion where programmability is unnecessary.

FAQ
What is the actual delay tolerance of DS1100Z-250/T&R over its full operating temperature range?
The DS1100Z-250/T&R exhibits ±13% delay tolerance over –40°C to +85°C, resulting in a 250ns nominal delay varying between 217.5ns and 282.5ns. This percentage-based spec applies because the nominal delay exceeds 40ns, per the device's AC Electrical Characteristics table and Note 1 in the datasheet.
Can DS1100Z-250/T&R operate from a 3.3V supply?
No, DS1100Z-250/T&R is specified only for 5.0V ±5% operation (4.75V–5.25V). Its DC Electrical Characteristics - including VIH, VIL, and ICC - are validated exclusively at 5V. Using 3.3V will result in undefined logic thresholds, degraded noise margin, and potential failure to meet timing specs.
How many 74LS loads can each tap of DS1100Z-250/T&R drive reliably?
Each tap of DS1100Z-250/T&R can drive up to 10 × 74LS loads, as confirmed in the General Description section. This is supported by its guaranteed IOL = 12mA and IOH = –1mA output drive capability under worst-case conditions (VCC = 4.75V, TA = +85°C).
Is DS1100Z-250/T&R pin-compatible with other DS1100 variants like DS1100Z-100/T&R?
Yes, all DS1100Z-xxx variants share identical SO-8 pinout and electrical interface. The only difference is the nominal delay value per tap - TAP1 through TAP5 scale linearly with the suffix (e.g., DS1100Z-100 yields 20ns/40ns/60ns/80ns/100ns). No PCB redesign is needed when substituting within the DS1100Z family.
Does DS1100Z-250/T&R require external bypass capacitors?
Yes, DS1100Z-250/T&R requires a 0.1μF ceramic bypass capacitor placed as close as possible between Pin 1 (VCC) and Pin 8 (GND). This is essential to suppress supply noise and maintain delay stability, especially during fast edge transitions - explicitly noted in the Test Conditions section and implied by the 50mA active current spec.
