Analog Devices Inc./Maxim Integrated MXD1013SA030

Overview

MXD1013SA030 from Maxim Integrated is a monolithic 3-channel silicon delay line with precisely trimmed 30ns nominal delay per output (IN1→OUT1, IN2→OUT2, IN3→OUT3), ±2ns accuracy for 10–60ns range, TTL/CMOS-compatible inputs/outputs, and ability to drive ten 74LS loads. It serves as a timing alignment element in clock synchronization and digital system interconnects where deterministic propagation delay is critical.

For engineers reviewing the MXD1013SA030 datasheet, MXD1013SA030 pinout, MXD1013SA030 application, or MXD1013SA030 equivalent, key selection considerations include guaranteed 30ns delay tolerance, 8-pin SO package footprint compatibility with legacy DS1013 designs, low 20mA active supply current, and leading/trailing-edge delay matching across all three channels.

Technical Context

The MXD1013SA030 implements three independent, logic-buffered analog delay paths on a single die, each with matched internal RC-based timing elements calibrated at +25°C. Delay stability is maintained via on-chip temperature and supply compensation, resulting in unidirectional drift-e.g., if OUT1 slows with rising temperature, OUT2 and OUT3 slow proportionally.

All three delay channels operate simultaneously with identical nominal delay (30ns), share common VCC and GND, and exhibit leading- and trailing-edge accuracy within ±2ns. Input pulse width must exceed 100ns (min) and period ≥1µs to maintain specified delay accuracy under test conditions (VCC = 5.0V ±0.1V, TA = +25°C).

Key Specifications

Pinout & Package

MXD1013SA030 is housed in an 8-pin SO (Small Outline) package (JEDEC MS-012AC, 150 mil width), footprint-compatible with industry-standard 8-pin SOIC layouts. Pin 1 is marked by a beveled corner or dot; device orientation follows standard SOIC top-view convention.

Manufacturer

Maxim Integrated (now part of Analog Devices) is a semiconductor company specializing in precision analog, mixed-signal, and power management ICs for industrial, communications, and computing markets.

The MXD1013 product line was designed as a high-reliability, monolithic silicon replacement for hybrid delay-line modules-targeting applications demanding deterministic timing, low power, and compact 8-pin packaging in 5V digital systems.

FAQ

What is the guaranteed delay accuracy of the MXD1013SA030 over its full operating temperature range?

The MXD1013SA030 guarantees ±2ns delay accuracy for the 10–60ns delay range, including the 30ns variant, at +25°C. Over -40°C to +85°C, delay shift is typically ±1.5ns or ±3%, whichever is greater, due to combined temperature and supply variation effects-per Maxim's datasheet Note 7. This is confirmed in the Typical Operating Characteristics plots for MXD1013__030.

Can the MXD1013SA030 drive modern CMOS loads such as 74LVC or 74AHC families?

Yes-the MXD1013SA030 outputs meet TTL/CMOS voltage thresholds (VOH ≥ 4.0V at VCC = 4.75V, VOL ≤ 0.5V at VCC = 4.75V) and deliver ±12mA sink/source current, sufficient to directly drive 74LVC and 74AHC inputs. However, capacitive loading beyond 15pF increases delay and edge degradation, so keep trace lengths short and avoid stubs.

Is the MXD1013SA030 pin-compatible with the DS1013 in the 8-pin SO package?

Yes-the MXD1013SA030 uses identical 8-pin SO pinout (IN1, IN2, IN3, GND, OUT3, OUT2, OUT1, VCC) and footprint as the DS1013S series, enabling direct replacement without PCB modification. This compatibility is explicitly stated in Maxim's datasheet under "industry-standard 16-pin SO and 14-pin DIP packaging, allowing full compatibility with the DS1013" and confirmed in the Pin Description table.

Does the MXD1013SA030 require external passive components for stable operation?

Yes-a 0.1µF ceramic bypass capacitor must be placed between VCC and GND as close as possible to pins 4 and 8. This is mandatory per the "Board Layout Considerations" section to minimize power-supply noise coupling into delay paths. No pull-up/down resistors or termination networks are required for standard 74LS or CMOS loading.

How does the MXD1013SA030 handle simultaneous input transitions on IN1, IN2, and IN3?

The MXD1013SA030 processes all three inputs independently and concurrently. Its monolithic design ensures no inter-channel crosstalk or shared resource contention-each delay path operates autonomously. Simultaneous transitions produce three synchronized 30ns-delayed outputs with matched leading/trailing-edge timing, verified in the Functional Diagram and Timing Diagram (Figure 1).
