DESCRIPTION
The DS1000 series delay lines have five equally spaced taps providing delays from 4 ns to 500 ns. These
devices are offered in a standard 14-pin DIP that is pin-compatible with hybrid delay lines. Alternatively,
8-pin DIPs and surface mount packages are available to save PC board area. Low cost and superior
reliability over hybrid technology is achieved by the combination of a 100% silicon delay line and
industry standard DIP and SOIC packaging. In order to maintain complete pin compatibility, DIP
packages are available with hybrid lead configurations. The DS1000 series delay lines provide a nominal
accuracy of ±5% or ±2 ns, whichever is greater. The DS1000 5-Tap Silicon Delay Line reproduces the
input logic state at the output after a fixed delay as specified by the extension of the part number after the
dash. The DS1000 is designed to reproduce both leading and trailing edges with equal precision. Each
tap is capable of driving up to ten 74LS loads. Dallas Semiconductor can customize standard products to
meet special needs. For special requests and rapid delivery, call 972-371-4348.
