Analog Devices Inc./Maxim Integrated MXD1013PA075

Overview

MXD1013PA075 from Maxim Integrated is a monolithic, triple-output silicon delay line with three independent, logic-buffered delay paths-each delivering a precise 75ns nominal delay at +25°C and VCC = 5V. It features ±3% delay accuracy (70–100ns range), TTL/CMOS-compatible inputs/outputs, and drives up to ten 74LS loads. It is used in clock synchronization and digital system timing alignment where deterministic, low-jitter signal skew correction is required.

For engineers reviewing the MXD1013PA075 datasheet, MXD1013PA075 pinout, MXD1013PA075 application, or MXD1013PA075 equivalent, key selection criteria include guaranteed 75ns delay tolerance, industrial temperature operation (−40°C to +85°C), 8-pin PDIP package compatibility with legacy DS1013 footprints, and supply current of 20mA-half that of Dallas' original DS1013.

Technical Context

The MXD1013PA075 implements three fully independent delay paths on a single die, each with matched leading- and trailing-edge accuracy (±3% over 70–100ns). Delay stability is maintained across temperature and supply voltage via internal compensation, with typical delay shift ≤±3% over −40°C to +85°C and ±5% over VCC = 4.75V–5.25V.

All three outputs are buffered, rail-to-rail compatible, and electrically isolated-enabling simultaneous use without crosstalk-induced timing error. Input pulse width must exceed 100ns (min), and output loading follows standard 74F04 gate equivalence per channel for specified timing accuracy.

Key Specifications

Pinout & Package

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog and mixed-signal ICs for timing, power, sensing, and communication applications.

The MXD1013 product line was engineered as a high-reliability, low-power silicon replacement for hybrid and older bipolar delay lines-targeting industrial, test, and telecom infrastructure where deterministic timing and long-term stability are critical.

FAQ

What is the guaranteed delay accuracy of MXD1013PA075 over its full operating temperature range?

The MXD1013PA075 guarantees ±3% delay accuracy for the 75ns nominal delay over the full −40°C to +85°C range, as confirmed by design characterization and typical performance curves in the datasheet. This specification accounts for combined effects of temperature and supply variation, with worst-case drift remaining within ±3% relative to the 75ns value at +25°C.

Is MXD1013PA075 pin-compatible with the original DS1013-75 in an 8-pin DIP socket?

Yes, MXD1013PA075 uses the identical 8-pin DIP pinout as DS1013-75: IN1 (pin 1), IN2 (pin 2), IN3 (pin 3), GND (pin 4), OUT1 (pin 5), OUT2 (pin 6), OUT3 (pin 7), and VCC (pin 8). No PCB or socket modification is required for drop-in replacement.

Can MXD1013PA075 drive modern CMOS loads such as 74LVC or FPGA I/Os directly?

Yes, MXD1013PA075 outputs are TTL/CMOS-compatible with VOH ≥2.4V and VOL ≤0.5V under rated load, meeting 74LVC input thresholds. Its 20mA drive strength exceeds typical LVC input leakage and capacitive requirements, enabling direct connection without series termination or level shifters.

Does MXD1013PA075 require external decoupling capacitors, and if so, what value and placement is recommended?

Yes, a 0.1µF ceramic capacitor must be placed between VCC (pin 8) and GND (pin 4) as close as possible to the MXD1013PA075 package. This minimizes high-frequency supply noise induced by internal switching, which could otherwise modulate delay stability-especially critical for sub-nanosecond edge alignment.

How does the delay of MXD1013PA075 change with supply voltage variation?

Over VCC = 4.75V to 5.25V, MXD1013PA075 delay shifts by ≤±3% (relative to 75ns), as specified in the datasheet's "Supply and Temperature Effects on Delay" section. This is internally compensated-no external calibration is needed, and the shift is monotonic and predictable across all three outputs.
