DALLAS SEMICONDUCTOR TEST CIRCUIT Figure 8
TEST SETUP DESCRIPTION
Figure 8 illustrates the hardware configuration used for measuring the timing parameters of the DS1023.
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 DS1023 serial and
parallel ports are controlled by interfaces to a central computer. All measurements are fully automated
with each instrument controlled by the computer over an IEEE 488 bus.
TEST CONDITIONS

Period:
NOTE: Above conditions are for test only and do not restrict the operation of the device under other data
sheet conditions.
OUTPUT:
Output is loaded with a 74F04. Delay is measured between the 1.5V level of the rising edge of the input
signal and the 1.5V level of the corresponding edge of the output.
