DS1135U-20+T&R

Delay Lines IC Overview

The DS1135U-20+T&R is a high-speed silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It integrates three independent buffered delays within a single package, operating at +5V. The device provides a nominal delay of 20ns per output with an initial tolerance of ±1.5ns and a maximum tolerance over temperature and voltage of ±2ns across the -40°C to +85°C range. It utilizes an 8-pin SOIC (150-mil) package and supports tape and reel packaging for automated assembly.
