FEATURES
DESCRIPTION
The DS1044 series is a 4–in–1 version of the low–
power, +5 Volt, high speed, DS1035.
The DS1044 series of delay lines have four independent
logic buffered delays in a single package. The device is
Dallas Semiconductor’s fastest 4–in–1 delay line. It is
available in a standard 14–pin DIP and 14–pin SOIC.
The device features precise leading and trailing edge
accuracies. It has the inherent reliability of an all–silicon
All–silicon timing circuit
Four independent buffered delays
Initial delay tolerance 1.5 ns
Stable and precise over temperature and voltage
Leading and trailing edge precision preserves the
input symmetry
Standard 14–pin DIP, 14–pin SOIC (150 mil)
Vapor phase, IR and wave solderable
Available in Tape and Reel
4–in–1 High–Speed Silicon Delay Line

delay line solution. The DS1044’s nominal tolerance is
and voltage of 1.0 ns for the faster delays. Each output
is capable of driving up to 10 LS loads.
Standard delay values are indicated in Table 1. Cus-
