DESCRIPTION
The DS1135 series is a low-power, +5V 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 our fastest 3-in-1 delay line. It is available in a standard 8-pin 150-mil SO.
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.

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 (20ps 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.
