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.

Nominal conditions are +25C and V =+5.0V. CC 2. Voltage range of 4.75V to 5.25V. 3. Delay accuracies are for both leading and trailing edges. 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. 2 of 7
