Product details
Overview
MXD1000SA200 from Maxim Integrated is a 5-tap silicon delay line with nominal tap delays of 40ns, 80ns, 120ns, 160ns, and 200ns (TAP1–TAP5), ±2ns or ±5% delay tolerance, TTL/CMOS-compatible inputs/outputs, and 20mA typical supply current at +5V. It serves as a precise timing element in clock synchronization and digital signal alignment circuits.
For engineers reviewing the MXD1000SA200 datasheet, MXD1000SA200 pinout, MXD1000SA200 application, or MXD1000SA200 equivalent, this page provides verified package mapping (8-pin µMAX), confirmed tap delay values per pin, absolute maximum ratings, temperature- and voltage-dependent delay behavior, and direct alternatives for delay-line replacement in high-reliability digital systems.
Technical Context
The MXD1000SA200 implements a monolithic silicon delay architecture with five fixed, equally spaced taps derived from a single input signal path. Each tap delivers deterministic propagation delay relative to the input edge, with leading- and trailing-edge accuracy maintained across temperature and supply voltage variations.
Delay variation is unidirectional-e.g., if TAP2 slows with rising temperature, all other taps slow proportionally-ensuring consistent inter-tap spacing. The device operates at VCC = +5.0V ±5%, supports 74LS load driving (up to ten loads per tap), and exhibits <4% delay shift over VCC = +4.75V to +5.25V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Tap Delays | TAP1=40ns, TAP2=80ns, TAP3=120ns, TAP4=160ns, TAP5=200ns - defines fixed, non-adjustable timing offsets for signal sampling or skew correction |
| Delay Tolerance | ±2ns or ±5%, whichever greater - sets worst-case timing margin for setup/hold validation in synchronous logic |
| Supply Voltage | +5.0V ±5% - requires stable 5V rail; delay varies <4% across full specified range |
| Supply Current | 20mA typical (vs. DS1000's 35mA) - reduces power budget and thermal load in dense PCB layouts |
| Output Drive | Drives up to ten 74LS loads - ensures fanout capability without external buffering in legacy TTL systems |
| Operating Temp | -40°C to +85°C - qualified for industrial environments without derating |
| Input Compatibility | TTL/CMOS logic levels - interoperable with both 5V logic families without level translation |
Pinout & Package
MXD1000SA200 is housed in an 8-pin µMAX package (3mm × 3mm, 0.5mm pitch), pin-compatible with DS1000-series delay lines and suitable for space-constrained digital timing applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Signal Input | Primary TTL/CMOS-compatible input; accepts 5V logic edges with ≤3ns rise/fall time |
| 2 (TAP1) | Tap Output 1 | Delivers input signal delayed by 40ns (20% of TAP5); used for early-phase sampling |
| 3 (TAP2) | Tap Output 2 | Delivers input signal delayed by 80ns (40% of TAP5); enables mid-cycle alignment |
| 4 (TAP3) | Tap Output 3 | Delivers input signal delayed by 120ns (60% of TAP5); supports intermediate timing points |
| 5 (TAP4) | Tap Output 4 | Delivers input signal delayed by 160ns (80% of TAP5); used for late-phase signal conditioning |
| 6 (TAP5) | Tap Output 5 | Delivers input signal delayed by 200ns (100% of TAP5); defines maximum delay reference |
| 7 (VCC) | Power Supply | +5.0V ±5% supply input; requires local 0.1µF ceramic decoupling |
| 8 (GND) | Ground Reference | Logic ground return; must be low-impedance connection to minimize delay jitter |
Key Features
| Feature | Design Value |
|---|---|
| Leading- and trailing-edge accuracy | Guaranteed tPLH/tPHL matching within ±2ns - enables precise dual-edge timing control in strobe or latch circuits |
| Unidirectional delay drift | All taps track identically with temperature/voltage - preserves inter-tap spacing critical for phase-aligned sampling |
| Low active current | 20mA typical vs. 35mA for DS1000 - lowers system power and eases thermal management in multi-device timing trees |
| 8-pin µMAX footprint | 3mm × 3mm body, 0.5mm pitch - saves >50% board area versus 14-pin DIP while maintaining pin compatibility |
| DS1000 drop-in replacement | Identical pinout and logic interface - allows direct substitution without PCB redesign or firmware changes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 5-tap fixed-delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1000-200 | Same 200ns max delay, but 35mA supply current and 14-pin DIP only; ±5% tolerance only (no ±2ns option) | Requires PCB layout change for DIP footprint; higher power draw limits density in compact designs | Select DS1000-200 only when µMAX footprint is incompatible and legacy DIP sockets must be retained. |
| MXD1000SE200 | Same silicon core and delay specs, but in 16-pin narrow SO package; identical electrical performance and temperature range | Offers surface-mount alternative with larger pad pitch (0.65mm) for easier hand-soldering or rework | Choose MXD1000SE200 when µMAX assembly capability is unavailable but SO-16 reflow is supported. |

FAQ
What is the exact delay value for each tap of the MXD1000SA200?
The MXD1000SA200 provides five fixed tap delays referenced to the input signal: TAP1 = 40ns, TAP2 = 80ns, TAP3 = 120ns, TAP4 = 160ns, and TAP5 = 200ns. These values are specified at +25°C and VCC = +5.0V, with tolerance of ±2ns or ±5%, whichever is greater. All delays scale uniformly with temperature and supply voltage due to unidirectional drift behavior.
Is the MXD1000SA200 pin-compatible with the DS1000 series?
Yes, the MXD1000SA200 uses the same 8-pin µMAX pinout as the DS1000-200 variant and maintains functional and mechanical compatibility with DS1000 family devices. Pin assignments for IN, TAP1–TAP5, VCC, and GND match exactly, enabling drop-in replacement without PCB modification.
What is the maximum capacitive load the MXD1000SA200 can drive per tap?
The MXD1000SA200 is rated to drive up to ten 74LS logic inputs per tap under standard conditions (VCC = +5V, TA = +25°C). Exceeding this load increases output rise/fall times and may extend measured tap delays; for heavier loads, external buffer stages are recommended to maintain timing accuracy.
Does the MXD1000SA200 require external decoupling capacitors?
Yes, a 0.1µF ceramic bypass capacitor is required between VCC (Pin 7) and GND (Pin 8) as close to the package as possible. This minimizes supply noise-induced jitter and ensures stable delay performance, especially under fast-switching or high-fanout conditions.
How does supply voltage variation affect the delay accuracy of the MXD1000SA200?
Voltage variation causes delay shifts of less than 4% over the full VCC range (+4.75V to +5.25V). For example, at VCC = +4.75V, the 200ns TAP5 delay may reduce to ~192ns. This effect is monotonic and tracked across all taps, preserving inter-tap spacing-critical for phase-sensitive applications.
