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.
