Analog Devices Inc./Maxim Integrated MXD1013SA075

Overview

MXD1013SA075 from Maxim Integrated is a monolithic 3-channel silicon delay line with precisely trimmed 75ns nominal delay per output (tPLH/tPHL), ±3% accuracy over 70–100ns range, TTL/CMOS-compatible inputs/outputs, and 20mA active supply current. It operates from -40°C to +85°C and drives up to ten 74LS loads-used in clock synchronization and digital system timing alignment where deterministic, low-jitter signal delay is required.

For engineers reviewing the MXD1013SA075 datasheet, MXD1013SA075 pinout, MXD1013SA075 application, or MXD1013SA075 equivalent, key selection considerations include its fixed 75ns delay tolerance, 8-pin SO package footprint, single-supply 5V operation, leading/trailing-edge accuracy, and compatibility with legacy DS1013-based designs requiring space-constrained, low-power delay solutions.

Technical Context

The MXD1013SA075 implements three independent, logic-buffered delay paths on a single die, each with matched propagation characteristics and unidirectional temperature/supply drift behavior. Its delay is internally compensated and specified at VCC = 5.0V ±5% and TA = +25°C, with typical ±3% variation across the full -40°C to +85°C operating range.

All three channels share a common 5V supply and ground, accept standard TTL/CMOS logic levels, and deliver outputs with guaranteed rise/fall times suitable for driving 74LS loads directly. Input pulse width must be ≥100ns, and period ≥1µs under test conditions to maintain specified delay accuracy.

Key Specifications

Pinout & Package

FAQ

What is the exact delay specification for MXD1013SA075 at +25°C and 5V?

The MXD1013SA075 delivers a nominal 75ns input-to-output delay (tPLH and tPHL) at +25°C and VCC = 5.0V, with ±3% accuracy as specified in the timing characteristics table. This applies identically to all three channels (OUT1, OUT2, OUT3) under standard test conditions using 1.5V threshold measurement points and 74F04-equivalent loading.

Is MXD1013SA075 pin-compatible with DS1013 devices?

Yes - MXD1013SA075 uses the same 8-pin SO package and identical pinout as DS1013S variants (IN1–IN3, GND, VCC, OUT1–OUT3), enabling direct PCB-level replacement without layout changes. Electrical compatibility is confirmed via TTL/CMOS I/O thresholds and matching drive strength.

Does MXD1013SA075 require external decoupling capacitors?

Yes - a 0.1µF ceramic capacitor must be placed as close as possible to the VCC and GND pins of MXD1013SA075 to suppress high-frequency switching noise. This is explicitly required in the Applications Information section to maintain delay accuracy and prevent supply-induced jitter.

Can MXD1013SA075 operate with input pulses shorter than 100ns?

No - the datasheet specifies a minimum input pulse width (tWI) of 100ns. Pulses narrower than this may result in degraded delay accuracy or failure to propagate reliably, as the internal circuitry requires sufficient time to resolve logic transitions and stabilize output states.

How does temperature affect the delay of MXD1013SA075?

Over -40°C to +85°C, MXD1013SA075 exhibits correlated, unidirectional delay drift across all three outputs - e.g., if OUT1 slows by 1.2%, OUT2 and OUT3 slow by approximately the same amount. Typical total variation remains within ±3% of nominal 75ns, as confirmed by TOC2–TOC4 plots in the datasheet.
