5-Tap Silicon Delay Line
_______________General Description
T h e 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 e n h a n c e d 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 - p i n SO or DIP, allowing full compatibility with the DS1000 and other delay line products.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Contact factory for ordering information. Specifications to -40°C are guaranteed by design, not production tested. All voltages referenced to GND. Measured with output open. ICC is a function of frequency and TAP5 delay. Only an MXD1000_ _25 operating with a 40ns period and VCC = +5.25V will have an ICC = 75mA. For example, an MXD1000_ _100 will never exceed 30mA. See Supply Current vs. Input Frequency in Typical Operating Characteristics. Note 6: Guaranteed by design. Note 7: Pulse width and/or period specifications may be exceeded, but accuracy is application sensitive (i.e., layout, decoupling, etc.). The device will remain functional with pulse widths down to 20% of TAP5 delay, and input periods as short as 2(tWI). Note 8: Typical initial tolerances are ± with respect to the nominal value at +25°C and VCC = 5V. Note 9: Typical temperature tolerance is ± with respect to the initial delay value over a temperature range of -40°C to +85°C. Note 10: The delay will also vary with supply voltage, typically by less than 4% over the supply range of VCC = +4.75V to +5.25V. Note 11: All tap delays tend to vary unidirectionally with temperature or voltage changes. For example, if TAP1 slows down, all other taps will also slow down; i.e., TAP3 can never be faster than TAP2. 2 _______________________________________________________________________________________
