5-Tap Silicon Delay Line
_______________General Description
The MXD1005 silicon delay line offers five equally
spaced taps with delays ranging from 12ns to 250ns
and a nominal accuracy of 卤2ns or 卤3%, 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 MXD1005 is available in multiple versions, each
offering a different combination of delay times. It comes
in the space-saving 8-pin 碌MAX package, as well as an
8-pin SO or DIP, allowing full compatibility with the
DS1005 and other delay line products.
