Dallas DS1110S-400 10-tap silicon delay line Datasheet

Rev 1; 11/03
10-Tap Silicon Delay Line
The DS1110 delay line is an improved replacement for
the DS1010. It has ten equally spaced taps providing
delays from 5ns to 500ns. The devices are offered in a
standard 16-pin SO or 14-pin TSSOP. The DS1110 series
delay lines provide a nominal accuracy of ±5% or ±2ns,
whichever is greater, at 5V and +25°C. The DS1110
reproduces the input logic state at the tap 10 output after
a fixed delay as specified by the dash number extension
of the part number. The DS1110 is designed to produce
both leading- and trailing-edge delays with equal precision. Each tap is capable of driving up to ten 74LS type
loads. Dallas Semiconductor can customize standard
products to meet special needs.

All voltages are referenced to ground.
Measured with outputs open.
Initial tolerances are ± with respect to the nominal value at +25°C and VCC = 5.0V for both leading and trailing edges.
Temperature and voltage tolerances are with respect to the actual delay measured over stated temperature range and a 4.75V
to 5.25V range.
Intermediate delay values are available on a custom basis.
See Test Conditions section.
All tap delays tend to vary unidirectionally with temperature or voltage changes. For example, if tap 1 slows down, all other
taps also slow down; tap 3 can never be faster than tap 2.
Pulse width and period specifications may be exceeded; however, accuracy is application sensitive (decoupling, layout, etc.)
For Tap 1 delays greater than 20ns, the tolerance is ±3ns or ±5%, whichever is greater.

Terminology
Period: The time elapsed between the leading edge of
the first pulse and the leading edge of the following pulse.
t WI (Pulse Width): The elapsed time on the pulse
between the 1.5V point on the leading edge and the
1.5V point on the trailing edge, or the 1.5V point on the
trailing edge and the 1.5V point on the leading edge.
tRISE (Input Rise Time): The elapsed time between the
20% and the 80% point on the leading edge of the
input pulse.
tFALL (Input Fall Time): The elapsed time between the
80% and the 20% point on the trailing edge of the
input pulse.
tPLH (Time Delay, Rising): The elapsed time between
the 1.5V point on the leading edge of the input pulse
and the 1.5V point on the leading edge of any tap output pulse.
tPHL (Time Delay, Falling): The elapsed time between
the 1.5V point on the trailing edge of the input pulse
and the 1.5V point on the trailing edge of any tap output pulse.
Test Setup Description
Figure 3 illustrates the hardware configuration used for
measuring the timing parameters on the DS1110. A
precision pulse generator under software control produces the input waveform. Time delays are measured
by a time interval counter (20ps resolution) connected
