DS1100LU-45+

Delay Lines IC Overview

The DS1100LU-45+ is a 3.3V five-tap silicon delay line from the DS1100L series, characterized for operation between 3.0V and 3.6V. It provides equally spaced delays of 9ns, 18ns, 27ns, 36ns, and 45ns across its taps. The device utilizes low-power CMOS technology with TTL/CMOS compatibility and operates within a temperature range of -40°C to +85°C. Packaged in an 8-pin µMAX format, it features precise leading and trailing-edge accuracy and can drive up to ten 74LS loads per tap.

Delay Lines IC FAQ

How does the delay tolerance vary with temperature?

For delays greater than 40ns, the input-to-tap delay tolerance ranges from -5% to +5% at +25°C, expanding to -13% to +13% over the full industrial temperature range of -40°C to +85°C.

What is the maximum load capacity per tap?

Each tap is capable of driving up to ten 74LS loads without degradation of signal integrity or timing accuracy.

Are intermediate delay values available?

Standard products provide fixed delays based on the part number suffix. Intermediate delay values are available on a custom basis through direct contact with the manufacturer.
