3V 10-Tap Silicon Delay Line
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.

All voltages are referenced to ground.
Measured with outputs open.
Initial tolerances are ± with respect to the nominal value at +25°C and V
CC
= 3.3V for both leading and trailing edges.
Temperature and voltage tolerances are with respect to the nominal delay value over stated temperature range and a 2.7V to
3.6V 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.
