DS1135LZ-30+T&R

Overview

The DS1135LZ-30+T&R is a low-power, 3V high-speed silicon delay line featuring three independent buffered delays in an 8-pin SOIC package. It provides a nominal delay of 30ns per output with an initial tolerance of ±1.5ns at +25°C and VCC = +3.3V. The device operates within a supply voltage range of 2.7V to 3.6V and supports an operating temperature range from -40°C to +85°C. Key electrical characteristics include an active current of 10mA at 3.6V, input leakage of ±1.0µA, and output rise/fall times of approximately 2.5ns. The part is supplied in tape and reel packaging.

Feature Summary

• All-silicon timing circuit providing stable and precise delays over temperature and voltage variations
• Three independent logic buffered delays preserving input symmetry through leading and trailing edge precision
• Compatible with vapor phase, IR reflow, and wave soldering processes

Applications

• Replacement for DS1033 in existing designs
• Precision timing applications requiring multiple independent delay paths
• Systems utilizing 3V power supplies

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm RoHS compliance status and package type. Ensure that the tape and reel quantity matches the required production volume. Confirm availability through authorized distributors as lead times may vary based on manufacturing schedules.

Selection Notes

Select this component when three independent delay lines are required within a single package. Verify that the 30ns delay value meets the system timing requirements. Ensure the 3V operation aligns with the target power supply constraints. Check that the SOIC package footprint fits the PCB layout design.

Part Context

The DS1135L series represents a low-power, 3V high-speed version of the popular DS1013, DS1033, and DS1035 series. It is designed as the fastest 3-in-1 delay line solution available from Maxim Integrated, offering inherent reliability through its all-silicon architecture.

Replacement Considerations

The datasheet explicitly recommends the DS1135L series as a replacement for the DS1033. Designers should verify pin compatibility and electrical specifications when transitioning from legacy parts.
