5-Tap Silicon Delay Line
_______________General Description
The MXD1000 silicon delay line offers five equally
spaced taps with delays ranging from 4ns to 500ns and
a nominal accuracy of ±2ns or ±5%, whichever is
greater. Relative to hybrid solutions, this device offers
enhanced performance and higher reliability, and
reduces overall cost. Each tap can drive up to ten 74LS
loads.
The MXD1000 is available in multiple versions, each
offering a different combination of delay times. It comes
in the space-saving 8-pin µMAX package, as well as an
8-pin SO or DIP, allowing full compatibility with the
DS1000 and other delay line products.
