DS1135LU-20+T&R

Overview

The DS1135LU-20+T&R is a low-power, 3V high-speed silicon delay line featuring three independent buffered delays in an 8-pin uSOP package. It provides a nominal delay of 20 ns per output with an initial tolerance of ±1.0 ns at +25°C and VCC = +3.3V. The device operates within a supply voltage range of 2.7V to 3.6V and supports temperatures from -40°C to +85°C. Key electrical characteristics include a typical output rise/fall time of 2.5 ns, input capacitance of 10 pF, and active current of 10 mA at 3.6V. It preserves input symmetry through precise leading and trailing edge accuracy.

Feature Summary

• All-silicon timing circuit providing inherent reliability
• Three independent logic buffered delays in a single package
• Stable and precise performance over temperature and voltage variations
• Preserves input symmetry via leading and trailing edge precision

Applications

• Replacement for DS1033
• Precision timing applications requiring stable delays
• Systems needing multiple independent delay lines in compact packaging

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and RoHS compliance status. Confirm availability and lead times directly with authorized distributors or the manufacturer, as stock levels fluctuate. Ensure the procurement channel is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when a 3V operation is required instead of standard 5V variants like the DS1135Z series. Choose the 20 ns delay value if that specific timing offset matches the design requirements. Verify that the 8-pin uSOP footprint fits the PCB layout constraints compared to standard SOIC packages.

Part Context

This part belongs to the DS1135L series, which represents the low-voltage 3V version of the popular DS1013, DS1033, and DS1035 delay lines. The 'LU' designation indicates the 8-pin uSOP (118 mil) package variant, while the '+T&R' suffix denotes lead-free/RoHS-compliant construction supplied in tape and reel format.

Replacement Considerations

Officially recommended as a replacement for the DS1033. Designers should verify pin compatibility and voltage level differences when substituting 5V parts like the DS1135Z series.
