DESCRIPTION
The DS1135 series is a low-power, +5-volt high-speed version of the popular DS1013 and DS1035.
The DS1135 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, as well as an 8-pin, 118 mil uSOP.
The device features precise leading and trailing edge accuracy. It has the inherent reliability of an all-
silicon delay line solution. 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
(972) 371-4348 for further information on custom delay values.

TEST SETUP DESCRIPTION
Figure 2 illustrates the hardware configuration used for measuring the timing parameters of the DS1135.
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 DS1135 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.

NOTES:
1. All voltages are referenced to ground.
2. Pulse width and duty cycle specifications may be exceeded, however, accuracy will be application
sensitive with respect to decoupling, layout, etc.
3. Power-up time is the time from the application of power to the time stable delays are being produced
at the output.
