Product details
Overview
DS1100M-100 from Maxim Integrated is a 5-tap silicon delay line delivering precisely spaced 20ns, 40ns, 60ns, 80ns, and 100ns delays at 5V supply, with ±4ns tolerance over -40°C to +85°C, TTL/CMOS-compatible outputs, and ability to drive up to 10 × 74LS loads-used in digital timing alignment, pulse shaping, and clock deskew circuits.
For engineers reviewing the DS1100M-100 datasheet, DS1100M-100 pinout, DS1100M-100 application, or DS1100M-100 equivalent, key selection factors include tap delay precision across temperature, leading/trailing edge matching, SO-8 vs. µMAX-8 package compatibility, and 5V-only operation with low-power CMOS design.
Technical Context
The DS1100M-100 implements an all-silicon delay architecture with five fixed, equally spaced output taps derived from a single input signal; each tap reproduces both rising and falling edges with matched propagation delay characteristics. Delay values are factory-trimmed and specified with initial ±2ns tolerance at +25°C/5V for ≤40ns delays, degrading to ±4ns over full industrial temperature range.
It operates exclusively at 5V (4.75V–5.25V), draws ≤50mA active current at 1MHz, and features 5pF typical input capacitance. Outputs meet TTL/CMOS voltage thresholds and sustain 12mA sink / 1mA source capability under load, enabling direct interface with legacy logic families without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Tap Delays | 20ns / 40ns / 60ns / 80ns / 100ns - fixed, monotonic spacing enables precise multi-point timing sampling |
| Delay Tolerance | ±4ns (≤40ns taps) or ±13% (>40ns taps) over -40°C to +85°C - ensures predictable skew in temperature-varying systems |
| Supply Voltage | 4.75V to 5.25V - compatible with standard 5V logic rails; no internal regulation required |
| Input Compatibility | TTL/CMOS - accepts VIH ≥2.2V and VIL ≤0.8V; supports direct connection to 74LS, 74F, and 74HC families |
| Output Drive | 12mA sink / 1mA source - sufficient to drive 10 × 74LS inputs without external buffers |
| Power Consumption | 30–50mA ICC at 1MHz - low static power enables use in power-constrained digital subsystems |
| Input Capacitance | 5–10pF - minimizes loading on high-speed source drivers and preserves signal integrity |
Pinout & Package
DS1100M-100 is packaged in an 8-pin SO (150 mils) surface-mount package per outline S8+4, with standardized land pattern 90-0096. Pin 1 is VCC, pin 5 is IN, pins 2/4/6/7/8 are TAP1–TAP5 respectively, and pin 3 is GND - identical pinout to DS1100Z-100 variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Positive supply | 5V power rail input; requires local 0.1µF bypass capacitor to ground |
| TAP 1 (Pin 2) | First delayed output | Delivers input signal delayed by 20ns; same edge fidelity as input |
| GND (Pin 3) | Reference ground | Common return path for supply and all I/O; must be low-impedance |
| TAP 3 (Pin 4) | Third delayed output | Delivers input signal delayed by 60ns; matches TAP1/TAP5 monotonic delay trend |
| IN (Pin 5) | Digital input | Accepts TTL/CMOS logic levels; 5–10pF input capacitance limits max frequency |
| TAP 2 (Pin 6) | Second delayed output | Delivers input signal delayed by 40ns; used for intermediate timing points |
| TAP 4 (Pin 7) | Fourth delayed output | Delivers input signal delayed by 80ns; enables four-step delay interpolation |
| TAP 5 (Pin 8) | Fifth delayed output | Delivers input signal delayed by 100ns; final tap for maximum delay interval |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon construction | Eliminates hybrid ceramic delay modules; improves long-term reliability and thermal stability |
| Equal tap spacing | Fixed 20ns increments enable linear time-domain sampling for jitter analysis and pulse train generation |
| Leading & trailing edge accuracy | Matched tPLH/tPHL ensures symmetrical delay for both signal transitions - critical for clock/data alignment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1000S-100 | Hybrid ceramic delay; ±5% delay tolerance; higher power consumption; only available in DIP-8 | Limited to lab/bench use due to larger footprint and lower reliability; not RoHS-compliant | Select DS1100M-100 for surface-mount production, tighter tolerance, and industrial temp support |
| MAX5517ETP+ | Programmable 8-tap delay IC; SPI-configurable; 10-bit resolution; 2.7V–5.5V supply | Requires microcontroller interface and firmware; suited for adaptive delay tuning, not fixed timing | Choose DS1100M-100 when deterministic, zero-overhead, hardware-only delay is required |
Compared with DS1000S-100 and MAX5517ETP+, the DS1100M-100 offers superior delay precision, smaller SO-8 footprint, and guaranteed industrial temperature operation - making it optimal for cost-sensitive, high-reliability fixed-delay implementations where simplicity and predictability outweigh programmability.

FAQ
What is the nominal delay progression across taps for DS1100M-100?
The DS1100M-100 provides five equally spaced delays: TAP1 = 20ns, TAP2 = 40ns, TAP3 = 60ns, TAP4 = 80ns, and TAP5 = 100ns - all referenced to the same input edge and verified at +25°C/5V per Maxim's datasheet Table 1. This fixed 20ns increment enables predictable multi-point timing sampling without configuration overhead.
Does DS1100M-100 support both rising and falling edge delays with equal accuracy?
Yes, DS1100M-100 is explicitly designed to reproduce both leading and trailing edges with matched precision. Its tPLH and tPHL delays are specified identically across all taps and temperature ranges - ensuring symmetrical delay behavior critical for clock/data alignment and PWM dead-time generation in the DS1100M-100.
What is the maximum capacitive load DS1100M-100 can drive reliably?
The DS1100M-100 is rated to drive up to 10 × 74LS logic inputs per tap, corresponding to approximately 100pF total load capacitance. Driving heavier loads may degrade delay accuracy and edge fidelity; for >10 LS loads, buffer amplification is recommended to maintain DS1100M-100 timing integrity.
Is DS1100M-100 compatible with 3.3V logic systems?
No, DS1100M-100 operates strictly at 5V (4.75V–5.25V) and is not 3.3V tolerant. Its input thresholds (VIH ≥2.2V, VIL ≤0.8V) and output drive levels are optimized for 5V TTL/CMOS systems. Interfacing with 3.3V logic requires level translation; the DS1100M-100 does not support dual-supply or mixed-voltage operation.
What package type is used for DS1100M-100, and is it RoHS-compliant?
DS1100M-100 uses the 8-pin SO (150 mils) surface-mount package per outline S8+4, and the "+" suffix confirms RoHS compliance and lead(Pb)-free construction. It shares pinout and footprint with DS1100Z-100 variants and supports vapor-phase, IR, and wave soldering per Maxim's package documentation for DS1100M-100.
