Detailed Description
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 dri-
ving up to ten 74LS type loads. Dallas Semiconductor
can customize standard products to meet special
needs. For special requests call 972-371-4348.
