FUNCTIONAL DESCRIPTION

The 3D7304 Quadruple Delay Line product family consists of fixeddelay CMOS integrated circuits. Each package contains four matched, independent delay lines. Delay values can range from 10ns through 500ns. The input is reproduced at the output without inversion, shifted in time as per the user-specified dash number. The 3D7304 is TTLand CMOS-compatible, capable of driving ten 74LS-type loads, and features both risingand falling-edge accuracy.

The all-CMOS 3D7304 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 14-pin SOIC.

APPLICATION NOTES

OPERATIONAL DESCRIPTION

The 3D7304 quadruple delay line architecture is shown in Figure 1. The individual delay lines are 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-to-line 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 Maximum and an Absolute Maximum operating input frequency and a Minimum and an Absolute Minimum operating pulse width have been specified.

To guarantee the Table 1 delay accuracy for input frequencies higher than the Maximum Operating Frequency, the 3D7304 must be tested at the user operating frequency.

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.

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.

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 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 3D7304 must be tested at the user operating pulse width. Therefore, to facilitate production and device identification, the part number will include a
