DESCRIPTION
The DS1035 series is a low-power +5-volt high-speed version of the popular DS1013 and complements
the DS1033 +3.3 Volt version.
The DS1035 series of delay lines have three independent logic buffered delays in a single package. The
device is Dallas Semiconductor’s fastest 3-in-1 delay line. It is available in a standard 8-pin DIP and 150
Mil 8-pin Mini-SOIC.
The device features precise leading and trailing edge accuracies. It has the inherent reliability of an all-
silicon delay line solution. The DS1035’s initial tolerance is
±1.5
or
±2.0
ns with an additional tolerance
over temperature and voltage of
±1.0
ns or
±1.5
ns, depending on the delay value. Each output is capable
of driving up to 10 LS loads.
Standard delay values are indicated in Table 1. Customers may contact Dallas Semiconductor at (982)
371-4348 for further information.

TEST SETUP DESCRIPTION
Figure 2 illustrates the hardware configuration used for measuring the timing parameters of the DS1035.
The input waveform is produced by a precision pulse generator under software control. Time delays are
measured by a time interval counter (20 ps resolution ) connected to the output. The DS1035 output taps
are selected and connected to the interval counter by a VHF switch control unit. All measurements are
fully automated with each instrument controlled by the computer over an IEEE 488 bus.
