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.
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.
t
RISE
(Input Rise Time): The elapsed time between the
20% and the 80% point on the leading edge of the
input pulse.
t
FALL
(Input Fall Time): The elapsed time between the
80% and the 20% point on the trailing edge of the input
pulse.
t
PLH
(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.
t
PHL
(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
