DS1013S-50/T&R

Overview

The DS1013S-50/T&R is a multiple, nonprogrammable silicon delay line integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It features three independent delay lines housed in a 16-SOIC surface-mount package with a width of 7.50mm. The device operates within a supply voltage range of 4.75V to 5.25V and supports an operating temperature range from 0°C to +70°C. Each delay line provides a total available delay of 50ns, with the first tap occurring at 50ns. This component is classified under Clock & Timer ICs and is designated as obsolete.

Feature Summary

• Integrates three independent analog delay lines on a single silicon chip for compact timing solutions.
• Provides fixed, nonprogrammable delay characteristics suitable for applications requiring stable signal timing offsets.
• Utilizes a 16-pin SOIC surface-mount package designed for automated PCB assembly processes.

Applications

• Signal processing circuits requiring precise time-domain delays between parallel data paths.
• Timing alignment systems for synchronizing signals across different channels in communication equipment.
• Test and measurement instrumentation where fixed propagation delays are necessary for calibration or pulse shaping.

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted to secondary market distributors such as Rochester Electronics. Buyers must verify the authenticity and storage history of units obtained through these channels, as original manufacturing support has ceased. Cross-referencing part numbers with official datasheets is essential to ensure functional compatibility before integration into new designs.

Selection Notes

Engineers should consider that this specific variant offers a fixed 50ns delay per channel without programmability. If variable delay adjustment is required, alternative models from the same family, such as the DS1023 series, may be more appropriate. Designers must also account for the limited commercial temperature range and ensure that the 16-SOIC footprint aligns with existing board layouts, as lead times for obsolete parts can be unpredictable.

Part Context

The DS1013S belongs to the Maxim Integrated DS1013 family of silicon delay lines, which are designed to provide precise, matched delays for high-speed digital and analog signals. The 'S' suffix indicates the SOIC package option, while '-50' specifies the 50ns delay characteristic. The '/T&R' suffix denotes tape and reel packaging, facilitating high-volume surface-mount assembly. This family is distinct from programmable delay lines and focuses on fixed-time offset applications.

Replacement Considerations

Direct replacements are difficult due to the obsolete status. Potential alternatives include other multi-channel delay lines from Analog Devices or competitors like Texas Instruments (e.g., SN74ALS153), though pinouts and electrical characteristics will differ significantly. Verification against the original datasheet is mandatory to ensure interface compatibility.
