Delay values ranging from 10ns through 400ns may be specified via the device dash number. Each input is reproduced at the corresponding output without inversion, shifted in time as per user selection. The 3D3314 is 3.3V CMOS-compatible and features both rising- and fallingedge accuracy. The device is offered in a standard 14-pin auto-insertable DIP and a space saving surface mount 14-pin SOIC.

Therefore, to facilitate production and device identification, the part number will 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. OPERATIONAL DESCRIPTION The 3D3314 quad fixed delay line architecture is shown in Figure 1. Each delay line is composed of a number of delay cells connected in series. Each delay line produces at its output a replica of the signal present at its input, shifted in time. The delay lines are matched and share the same compensation signals, which minimizes line-toline delay deviations over temperature and supply voltage variations. 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 Recommended Maximum and an Absolute Maximum operating input frequency and a Recommended Minimum and an Absolute Minimum operating pulse width have been specified. OPERATING PULSE WIDTH The Absolute Minimum 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 Recommended Minimum 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. OPERATING FREQUENCY The Absolute Maximum 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. To guarantee the Table 1 delay accuracy for input pulse width smaller than the Recommended Minimum Pulse Width, the 3D3314 must be tested at the user operating pulse width. Therefore, to facilitate production and device identification, the part number will include a custom reference designator identifying the The Recommended Maximum 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 200 PPM/C, which is equivalent to a variation, over the 0C70C operating range, of ±1% or 0.25ns (whichever is greater) from the 25C delay settings. The power supply coefficient is reduced, over the 3.0V-3.6V operating range, to ±1% or 1ns (whichever is greater) of the delay settings at the nominal 3.3VDC power supply. POWER SUPPLY AND TEMPERATURE CONSIDERATIONS It is essential that the power supply pin be adequately bypassed and filtered. In addition, the power bus should be of as low an impedance construction as possible. Power planes are preferred. . The delay of CMOS integrated circuits is strongly dependent on power supply and temperature.
