General Description
The DS1110L 10-tap delay line is a 3V version of the
DS1110. It has 10 equally spaced taps providing delays
from 10ns to 500ns. The DS1110L series delay lines
provide a nominal accuracy of ±5% or ±2ns, whichever
is greater, at 3.3V and +25°C. The DS1110L is character-
ized to operate from 2.7V to 3.6V. The DS1110L
produces both leading- and trailing-edge delays with
equal precision. The device is offered in a standard
14-pin TSSOP.

Note 1: All voltages are referenced to ground.
Note 2: Measured with outputs open.
Note 3: Initial tolerances are ± with respect to the nominal value at +25°C and VCC = 3.3V for both leading and trailing edges.
Note 4: Temperature and voltage tolerances are with respect to the nominal delay value over stated temperature range and a 2.7V to
3.6V range.
Note 5: Intermediate delay values are available on a custom basis.
Note 6: See Test Conditions section.
Note 7: 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.
Note 8: Pulse width and period specifications may be exceeded; however, accuracy is application sensitive (decoupling, layout, etc.).
Note 9: For Tap 1 delays greater than 20ns, the tolerance is ±3ns or ±5%, whichever is greater.

Detailed Description
The DS1110L 10-tap delay line is a 3V version of
the DS1110. It has 10 equally spaced taps providing
delays from 10ns to 500ns. The device is offered in a
standard 14-pin TSSOP. The DS1110L series delay lines
provide a nominal accuracy of ±5% or ±2ns, whichever is
greater, at 3.3V and +25°C. The DS1110L is character-
ized to operate from 2.7V to 3.6V. The DS1110L repro-
duces the input-logic state at the tap 10 output after a
fixed delay as specified by the dash-number suffix of the
part number (Table 1). The DS1110L produces both lead-
ing- and trailing-edge delays with equal precision. Each
tap is capable of driving up to 10 74LS-type loads. Dallas
Semiconductor can customize standard products to meet
specific needs. Figure 1 is the DS1110_L logic diagram
and Figure 2 shows the timing diagram for the silicon
delay line.

Terminology
Period: The time elapsed between the leading edge of
the first pulse and the leading edge of the following pulse.
tWI (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 out-
put 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 out-
put pulse.
Test Setup Description
Figure 3 illustrates the hardware configuration used for
measuring the timing parameters on the DS1110L. A
precision pulse generator under software control pro-
duces the input waveform. Time delays are measured
by a time interval counter (20ps resolution) connected

and connected to the counter by a VHF switch-control
unit. All measurements are fully automated, with each
instrument controlled by a central computer over an
IEEE-488 bus.
Output
Each output is loaded with the equivalent of one 450Ω
resistor in parallel with a 15pF capacitor. Delay is mea-
sured at the 1.5V level on the rising and falling edge.
