DS1135LZ-20/T&R

Overview

The DS1135LZ-20/T&R is a low-power, 3V high-speed silicon delay line featuring three independent buffered delays in an 8-pin SO package. It operates on a supply voltage of 2.7V to 3.6V with an active current of 10mA at 3.6V. The device provides a nominal delay of 20ns per output with an initial tolerance of ±1.0ns. Delay accuracy over temperature and voltage ranges from -40°C to +85°C is specified as ±4.0ns. Input pulse width must be 100% of the delay value, and 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 preservation maintains input symmetry
• Stable timing performance across commercial and industrial temperature ranges

Applications

• Precision timing circuit applications requiring multiple synchronized delays
• Replacement for legacy DS1033 devices in existing designs
• High-speed signal processing where edge symmetry is critical

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via the datasheet revision history and ordering information section. Ensure the specific suffix matches the required tape and reel packaging format for automated assembly processes.

Selection Notes

Select this model when a 20ns delay is required with strict symmetry constraints. Verify that the system operates within the 2.7V to 3.6V supply range. Consider the 8-pin SO package dimensions for PCB layout compatibility. Evaluate thermal requirements against the -40°C to +85°C operating range specifications.

Part Context

This component belongs to the DS1135L series, which serves as a low-power, 3V high-speed variant of the DS1013, DS1033, and DS1035 families. The series utilizes all-silicon technology for inherent reliability. The 'Z' suffix denotes the 150-mil 8-pin SO package configuration.

Replacement Considerations

DS1033 is explicitly recommended as a replacement target for legacy designs. Verify pinout compatibility and electrical parameter alignment before substitution.
