Delay Line 1 Input
The 3D7304 Quadruple Delay Line product family consists of fixed-
delay 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 TTL-
and CMOS-compatible, capable of driving ten 74LS-type loads, and
features both rising- and 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.

OPERATIONAL DESCRIPTION
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.
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.
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 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.
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.
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
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 and/or 1.0ns,
whichever is greater. The power supply
coefficient is reduced, over the 4.75V-5.25V
operating range, to ±1% of the delay settings at
the nominal 5.0VDC power supply and/or 2.0ns,
whichever is greater. 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
POWER SUPPLY AND
TEMPERATURE CONSIDERATIONS
The delay of CMOS integrated circuits is strongly
dependent on power supply and temperature.
The monolithic 3D7304 programmable delay line
utilizes novel and innovative compensation
construction as possible. Power planes are
preferred.
