DS1013M-40

Overview

The DS1013M-40 is a silicon delay line manufactured by Analog Devices Inc. under the Maxim Integrated brand, belonging to the DS1013 series. It features three independent delay functions with a single tap per function and provides true output polarity. The device utilizes CMOS technology and operates within a supply voltage range of 4.75V to 5.25V. It supports a maximum input frequency of 8.33 MHz and delivers a fixed delay of 40ns to the first tap. The component is housed in an 8-pin PDIP package with a standard 0.300-inch width. It is designed for commercial temperature applications, operating between -40°C and +85°C.

Feature Summary

• Provides three independent delay lines with fixed timing characteristics
• Ensures accuracy on both leading and trailing signal edges
• Compatible with standard CMOS and TTL logic loads
• Offers high fan-out capability supporting up to ten 74LS loads per output

Applications

• Precision timing alignment in digital communication systems
• Signal synchronization in data acquisition circuits
• Clock distribution network adjustments

Procurement Notes

Verify the specific suffix M-40 against official datasheets to confirm the industrial temperature grade (-40°C to +85°C) and PDIP-8 packaging. Confirm RoHS compliance status as historical Maxim parts may vary. Check current availability as this component family has seen discontinuation notices for similar variants. Ensure the source document explicitly lists the DS1013M-40 part number to avoid confusion with the K or S suffixes which denote different packages or temperature ranges.

Selection Notes

Select the DS1013M-40 when a fixed 40ns delay is required for three channels in an industrial environment. Compare against the DS1013K-40 if a commercial temperature range (0°C to 70°C) suffices and a DIP-8 package is acceptable. Consider the DS1013S-40 if surface-mount SOIC packaging is preferred over through-hole DIP. Verify that the 8.33 MHz maximum input frequency meets the system clock requirements before finalizing the selection.

Part Context

The DS1013M-40 belongs to the Maxim Integrated DS1013 family of silicon delay lines. This series is characterized by its ability to provide precise, fixed delays for multiple channels using a simple interface. The 'M' suffix typically denotes the industrial temperature range variant within this product line. These components are often used in legacy designs requiring exact pulse widening or narrowing without programmable complexity.

Replacement Considerations

Publicly confirmed substitute part numbers for the specific DS1013M-40 variant were not found in the provided documentation. Cross-reference tools suggest checking the DS1013K-40 for commercial grade equivalents or the DS1013S-40 for surface mount options, though these differ in package and temperature rating.
