DS1100U-40+

Delay Lines IC Overview

The DS1100U-40+ is a five-tap silicon delay line manufactured by Analog Devices Inc./Maxim Integrated. It provides equally spaced output taps with a nominal total delay of 40 nanoseconds, resulting in individual tap delays of 8ns, 16ns, 24ns, 32ns, and 40ns. The device operates on a single +5V supply within a voltage range of 4.75V to 5.25V. It utilizes low-power CMOS technology and features TTL/CMOS-compatible logic levels. The component is housed in an 8-pin µMAX surface-mount package and supports operation across commercial and industrial temperature ranges from -40°C to +85°C.
