FUNCTIONAL DESCRIPTION The 3D7010 10-Tap Delay Line product family consists of fixed-delay CMOS integrated circuits. Each package contains a single delay line, tapped and buffered at 10 points spaced uniformly in time. Tap-to-tap (incremental) delay values can range from 8ns through 50ns. The input is reproduced at the outputs without inversion, shifted in time as per the user-specified dash number. The 3D7010 is TTL- and CMOScompatible, capable of driving ten 74LS-type loads, and features both rising- and falling-edge accuracy. The all-CMOS 3D7010 integrated circuit has been designed as a reliable, economic alternative to hybrid TTL fixed delay lines. It is offered in a standard 14-pin auto-insertable DIP and a space saving surface mount 16-pin SOIC.

The delay line is composed of a number of delay cells connected in series. Each delay cell produces at its output a replica of the signal present at its input, shifted in time. The delay cells are matched and share the same compensation signals, which minimizes tap-totap delay deviations over temperature and supply voltage variations. To guarantee the Table 1 delay accuracy for input frequencies higher than the Maximum Operating Frequency, the 3D7010 must be tested at the user operating frequency. Therefore, to facilitate production and device identification, the part number w ill include a custom reference designator identifying the intended frequency of operation. The programmed delay accuracy of the device is guaranteed, therefore, only at the user specified input frequency. Small input frequency variation about the selected frequency will only marginally impact the programmed delay accuracy, if at all. Nevertheless, it is strongly recommended that the engineering staff at DATA DELAY DEVICES be consulted. INPUT SIGNAL CHARACTERISTICS The Frequency and/or Pulse Width (high or low) of operation may adversely impact the specified delay accuracy of the particular device. The reasons for the dependency of the output delay accuracy on the input signal characteristics are varied and complex. Therefore a Maximum and an Absolute Maximum operating input frequency and a Minimum and an Absolute Minimum operating pulse width have been specified. OPERATING PULSE WIDTH The Absolute Minimum Operating Pulse Width (high or low) specification, tabulated in Table 1, determines the smallest Pulse Width of the delay line input signal that can be reproduced, shifted in time at the device output, with acceptable pulse width distortion. The Minimum Operating Pulse Width (high or low) specification determines the smallest Pulse Width of the delay line input signal for which the output delay accuracy tabulated in Table 1 is guaranteed. To guarantee the Table 1 delay accuracy for input pulse width smaller than the Minimum Operating Pulse Width, the 3D7010 must be tested at the user operating pulse width. Therefore, to facilitate production and device identification, the part number w ill include a OPERATING FREQUENCY The Absolute Maximum Operating Frequency specification, tabulated in Table 1, determines the highest frequency of the delay line input signal that can be reproduced, shifted in time at the device output, with acceptable duty cycle distortion. The Maximum Operating Frequency specification determines the highest frequency of the delay line input signal for which the output delay accuracy is guaranteed.

The thermal coefficient is reduced to 600 PPM/C, which is equivalent to a variation , over the 0C-70C operating range, of ±3% from the room-temperature delay settings. The pow er supply coefficient is reduced, over the 4.75V5.25V operating range, to ±2% of the delay settings at the nominal 5.0VDC power supply. It is essential that the pow er supply pin be adequately bypassed and filtered. In addition, the pow er bus should be of as low an impedance construction as possible. Pow er planes are preferred. POWER SUPPLY AND TEMPERATURE CONSIDERATIONS The delay of CMOS integrated circuits is strongly dependent on power supply and temperature.
