DS1135LU-12+T&R

Overview

The DS1135LU-12+T&R is a low-power, 3V high-speed silicon delay line from the DS1135L series. It integrates three independent buffered delays in an 8-pin uSOP package. The nominal delay per output is 12ns with an initial tolerance of ±1.0ns at +25°C and VCC = +3.3V. Operating voltage ranges from 2.7V to 3.6V, with active current typically 10mA at 3.6V. It supports industrial temperature operation from -40°C to +85°C.

Feature Summary

• Three independent logic buffered delays integrated into a single package
• Stable and precise timing performance over temperature and voltage variations
• Preserves input symmetry through precise leading and trailing edge accuracy

Applications

• Timing circuit applications requiring multiple synchronized delays
• Replacement for DS1033 in existing designs
• Systems requiring stable delays across commercial and industrial temperature ranges

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS compliance status via the '+' suffix designation. Ensure supply chain sources provide valid traceability documentation. Validate that the tape and reel packaging matches standard industry dimensions for the 8-pin uSOP form factor.

Selection Notes

Select this part when a 3V operating voltage is required instead of the standard 5V variants. Choose the 12ns delay value if specific timing offsets are needed within the DS1135L family. Consider the 8-pin uSOP package for space-constrained surface mount designs. Verify that the 10mA active current consumption fits the system power budget.

Part Context

This component belongs to the DS1135L series, which serves as a low-power, 3V version of the popular DS1013, DS1033, and DS1035 series. It represents the fastest 3-in-1 delay line solution in its category, offering all-silicon reliability without external components.

Replacement Considerations

Officially recommended as a replacement for the DS1033. Designers should verify pin compatibility and ensure the 3V supply rail meets the new device's requirements compared to legacy 5V parts.
