DS1110 Datasheet, PDF (5/8 Pages) Dallas Semiconductor – 10-Tap Silicon Delay Line

10-Tap Silicon Delay Line
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.
