DS1040Z-A15

Overview

The DS1040Z-A15 is a programmable delay line integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It features a single emitter with five taps, providing a total available delay of 75ns. The device operates on a supply voltage ranging from 4.75V to 5.25V and supports a maximum input frequency of 15.3846 MHz. Each tap increment provides a delay step of 15ns, with the first tap set at 15ns. Designed for surface mount installation, it is housed in an 8-SOIC package (0.154 inch width). The component functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Programmable delay generation with complementary outputs
• Five-tap architecture for precise pulse shaping
• CMOS technology compatible with TTL logic levels

Applications

• Pulse generator circuits requiring specific timing delays
• Clock signal distribution networks
• Timing adjustment in digital communication systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices, as this part may be discontinued. Ensure storage conditions meet moisture sensitivity level requirements before reflow soldering.

Selection Notes

Select this component when fixed delay steps of 15ns are required. Compare against other DS1040 variants if different total delay values or tap configurations are needed. Verify that the 8-SOIC package fits the PCB layout constraints and that the 5V supply voltage aligns with the system design.

Part Context

This part belongs to the DS1040 family of programmable delay lines. Variants such as DS1040Z-75+ share similar architectural features but differ in total delay specifications. The series is designed for applications requiring precise, adjustable time delays in digital signal processing.

Replacement Considerations

Check for direct substitutes within the DS1040 series with matching delay characteristics. Verify pin compatibility and electrical parameters before replacing. Consult manufacturer documentation for any updated versions or recommended alternatives.
