Product details
Overview
MXD1005PA075 from Maxim Integrated is a 5-tap silicon delay line with precisely spaced 75ns nominal delays per tap (tPLH/tPHL), ±2ns or ±3% accuracy, TTL/CMOS-compatible I/O, and 17mA typical supply current at +5V. It operates from -40°C to +85°C in an 8-pin µMAX package and drives up to ten 74LS loads-used for clock skew correction in high-speed digital systems.
For engineers reviewing the MXD1005PA075 datasheet, MXD1005PA075 pinout, MXD1005PA075 application, or MXD1005PA075 equivalent, key selection criteria include tap delay accuracy, edge-specific timing (tPLH/tPHL), temperature-stable unilateral delay drift, low ICC vs. legacy hybrid delay lines, and µMAX footprint compatibility with DS1005-based layouts.
Technical Context
The MXD1005PA075 implements a monolithic silicon delay chain with five fixed taps derived from a single input signal, where each tap delivers a cumulative delay increment of 75ns (TAP1 = 75ns, TAP2 = 150ns, ..., TAP5 = 375ns). Delay accuracy is specified as ±2ns or ±3%, whichever is greater, with leading- and trailing-edge matching confirmed at the 1.5V logic threshold.
It features unilateral delay variation: all taps shift synchronously with temperature or VCC changes-e.g., if TAP2 slows, TAP3–TAP5 slow proportionally-enabling robust skew management. The device draws 17mA typical ICC at 5.0V and supports 500ns minimum input pulse width under standard test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Delay per tap | 75ns nominal (tPLH/tPHL), enabling precise 75ns-step clock alignment |
| Delay accuracy | ±2ns or ±3%, whichever is greater-guarantees worst-case skew control |
| Supply current | 17mA typical at VCC = +5.0V-reduces thermal load vs. DS1005's 40mA |
| Output drive | Drives ≥10 74LS loads-supports fanout without buffering in TTL/CMOS systems |
| Operating range | -40°C to +85°C-qualified for industrial-grade embedded timing applications |
| Input logic level | TTL/CMOS-compatible (VIH ≥ 2.2V, VIL ≤ 0.8V)-interoperates with mixed-logic systems |
| Power-up time | 100ms maximum-ensures stable delay after power application |
Pinout & Package
MXD1005PA075 is housed in an 8-pin µMAX package (3.0mm × 3.0mm, 0.5mm pitch), pin-compatible with 8-pin SO and DIP variants. Pin functions are electrically identical across packages; µMAX offers space-constrained PCB integration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Signal input | Primary TTL/CMOS-compatible input driving all five delay taps |
| 2 TAP1 | First delay output | Delivers 75ns delayed copy of IN rising/falling edge (tPLH/tPHL) |
| 3 TAP2 | Second delay output | Delivers 150ns delayed copy-cumulative, fixed-interval tap |
| 4 GND | Ground reference | Logic and power ground; requires local 0.1µF ceramic decoupling |
| 5 TAP3 | Third delay output | Delivers 225ns delayed copy-maintains ±2ns absolute accuracy |
| 6 TAP4 | Fourth delay output | Delivers 300ns delayed copy-unilaterally tracks TAP1–TAP3 shifts |
| 7 TAP5 | Fifth delay output | Delivers 375ns delayed copy-maximum delay; defines tWI limit (500ns) |
| 8 VCC | Power supply | +5.0V ±5% supply; ICC sensitive to input frequency and TAP5 delay |
Key Features
| Feature | Design Value |
|---|---|
| Unilateral delay tracking | All taps shift identically with temperature/VCC-preserves inter-tap skew <1ns |
| Edge-accurate timing | tPLH and tPHL both specified at 1.5V threshold-ensures matched setup/hold margins |
| Low-power operation | 17mA ICC vs. 40mA for DS1005-reduces board-level power delivery burden |
| µMAX footprint | 3.0mm × 3.0mm, 0.5mm pitch-enables high-density placement in space-limited systems |
| Hybrid replacement | Direct functional upgrade over DS1005-no layout redesign needed for µMAX variant |
Applications

IC Role / Device Role / Timing Role: Acts as a passive, low-jitter delay node feeding fanout buffers to multiple downstream gates. Use Value: Supports ≥10 LS-load fanout per tap while maintaining 75ns step integrity-eliminating need for active repeaters. |
Use Scenario: Distributing synchronized clock edges to isolated I/O modules in programmable logic controllers. IC Role / Device Role / Timing Role: Generates temperature-stable, cumulative delays to phase-align distributed clock domains. Use Value: Unilateral delay drift ensures inter-module skew remains constant across operating temperature-preventing metastability in safety-critical sequencing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar silicon delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1005-75 | Hybrid construction; 40mA ICC; ±5ns accuracy; 14-pin DIP only | Higher power, larger footprint, looser delay tolerance-suitable only where µMAX space constraints don't apply | Select DS1005-75 only for legacy DIP-based designs requiring drop-in replacement without re-layout |
| MXD1005SA075 | Same silicon core; 8-pin SO package; identical electrical specs; 0°C to +70°C rating | Limited temperature range-unsuitable for extended industrial environments | Choose MXD1005SA075 for cost-sensitive commercial applications where full -40°C to +85°C operation is unnecessary |
Compared with DS1005-75 and MXD1005SA075, the MXD1005PA075 uniquely combines industrial temperature range, µMAX packaging, and 17mA low ICC-making it optimal for new designs prioritizing density, power efficiency, and wide-temperature reliability.

FAQ
What is the exact delay value per tap for MXD1005PA075?
The MXD1005PA075 provides five equally spaced taps with a nominal delay of 75ns per tap: TAP1 = 75ns, TAP2 = 150ns, TAP3 = 225ns, TAP4 = 300ns, and TAP5 = 375ns, measured as tPLH and tPHL at the 1.5V logic threshold under standard conditions (VCC = +5.0V, TA = +25°C). This 75ns step is fixed and confirmed in the Part Number and Delay Times table.
Does MXD1005PA075 support both rising- and falling-edge delay accuracy?
Yes, the MXD1005PA075 guarantees leading-edge (tPLH) and trailing-edge (tPHL) delay accuracy independently-both specified as ±2ns or ±3%, whichever is greater. This dual-edge precision is verified per the timing diagram and test conditions in the datasheet, ensuring reliable setup/hold timing in bidirectional or clocked logic interfaces.
What is the maximum capacitive load the MXD1005PA075 can drive per tap?
The MXD1005PA075 is rated to drive up to ten 74LS logic inputs per tap, corresponding to approximately 10 × 20pF = 200pF total load capacitance. Exceeding this load increases rise/fall times and may extend actual tap delays beyond specification-so proper termination and minimal trace capacitance are recommended for ±2ns accuracy.
Is MXD1005PA075 pin-compatible with DS1005 devices?
The MXD1005PA075 in the 8-pin µMAX package is not pin-compatible with DS1005 (14-pin DIP), but its 8-pin SO and DIP variants share identical pinouts with DS1005-75. For µMAX designs, a PCB layout change is required-but the electrical interface, timing behavior, and functional role remain fully compatible as a second-source upgrade.
How does temperature affect delay matching between taps in MXD1005PA075?
Temperature changes cause unilateral delay shifts across all taps-e.g., a +40°C rise slows TAP1, TAP2, TAP3, TAP4, and TAP5 by equal relative amounts. This preserves inter-tap spacing within ±0.5ns, making MXD1005PA075 highly effective for skew-critical applications like memory bus deskew where relative delay stability matters more than absolute delay.
