DS1100LU-30+

Delay Lines IC Overview

The DS1100LU-30+ is a 3.3V, five-tap silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3.0V to 3.6V and functions across an industrial temperature range of -40°C to +85°C. The device provides five equally spaced output taps with a nominal total delay of 30ns (Tap 1: 6ns, Tap 2: 12ns, Tap 3: 18ns, Tap 4: 24ns, Tap 5: 30ns). Packaged in an 8-pin µMAX format, it features low-power CMOS technology compatible with TTL and CMOS logic levels.
