DS1135Z-25+T&R

Overview

The DS1135Z-25+T&R is a high-speed, all-silicon delay line featuring three independent buffered delays in an 8-pin SO package. It operates on a +5V supply with a nominal delay of 25ns per output. Initial tolerance is ±1.5ns at +25°C, expanding to ±2ns over the -40°C to +85°C industrial temperature range and 4.75V to 5.25V voltage range. The device supports vapor phasing, IR, and wave soldering, with outputs capable of driving up to 10 LS loads.

Feature Summary

• Three independent buffered delay channels within a single package
• Precise leading and trailing edge accuracy preserving input symmetry
• All-silicon construction for inherent reliability and stability
• Compatible with standard surface-mount soldering processes

Applications

• Timing alignment in digital logic systems
• Clock skew compensation
• Pulse width adjustment circuits

Procurement Notes

Verify the suffix T&R indicates tape and reel packaging when ordering. Confirm the Z suffix corresponds to the 8-pin SOIC (150-mil) package. Ensure the + designation meets RoHS compliance requirements for your assembly process. Cross-reference the specific delay value of 25ns against system timing constraints before procurement.

Selection Notes

Select this component when precise, stable delay is required for three independent signals without external components. Compare the 25ns delay specification against other variants like DS1135Z-20+ or DS1135Z-30+ if different timing is needed. Consider the DS1135L if 3V operation is required instead of the standard 5V supply.

Part Context

This part belongs to the DS1135 series of high-speed silicon delay lines, serving as a recommended replacement for older models like the DS1013 and DS1035. It provides a compact solution for timing applications requiring multiple independent delays in a small footprint.

Replacement Considerations

The datasheet explicitly recommends the DS1135 series as a replacement for the DS1013 and DS1035. Verify pin compatibility and electrical characteristics when substituting these legacy parts.
