DS1100U-75+

Delay Lines IC Overview

The DS1100U-75+ is a five-tap silicon delay line from the DS1100 series, housed in an 8-pin µMAX surface-mount package. It provides equally spaced taps with a nominal total delay of 75ns, distributed as 15ns, 30ns, 45ns, 60ns, and 75ns per tap. The device operates on a single +5V supply within a range of 4.75V to 5.25V. It features low-power CMOS technology compatible with TTL/CMOS logic levels. The component supports both leading and trailing edge accuracy and can drive up to ten 74LS loads per tap. It functions reliably across an industrial temperature range of -40°C to +85°C.
