DS1135LU-30

Overview

The DS1135LU-30 is a low-power, 3V high-speed silicon delay line from the DS1135L series. It integrates three independent buffered delays in an 8-pin SO package. The nominal delay per output is 30ns with an initial tolerance of ±1.5ns at +25°C and VCC = +3.3V. Over the industrial temperature range (-40°C to +85°C) and voltage range (2.7V to 3.6V), the tolerance is ±5.0ns. The device operates on a single supply voltage between 2.7V and 3.6V, drawing a typical active current of 10mA at 3.6V. Output rise/fall times are typically 2.5ns.

Feature Summary

• Three independent logic buffered delays integrated into a single package
• Precise leading and trailing edge accuracy preserves input symmetry
• Stable and precise timing performance over temperature and voltage variations
• All-silicon solution providing inherent reliability

Applications

• Precision timing circuits requiring multiple synchronized delays
• High-speed signal processing applications
• Replacement for legacy DS1033 devices

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status via the datasheet or manufacturer documentation before integration. Ensure supply chain stability as this specific part number may have limited distribution compared to standard variants.

Selection Notes

Select the DS1135LU-30 when a 30ns delay value is required within the 3V operating range. Compare against the DS1135U-30 if 5V operation is necessary instead of 3V. Verify that the 8-pin SO package footprint matches the design layout requirements.

Part Context

The DS1135LU-30 belongs to the DS1135L series, which serves as 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 in its class, offering precise timing capabilities in a compact form factor.

Replacement Considerations

The datasheet recommends the DS1135LU-30 as a replacement for the DS1033 series. Verify pin compatibility and voltage level differences when substituting older generation delay lines.
