full-power response (continued)
input signal until the maximum frequency above which the output contains significant distortion is found. The
full-peak response is defined as the maximum output frequency, without regard to distortion, above which full
peak-to-peak output swing cannot be maintained.
Because there is no industry-wide accepted value for significant distortion, the full-peak response is specified
in this data sheet and is measured using the circuit of Figure 26. The initial setup involves the use of a sinusoidal
input to determine the maximum peak-to-peak output of the device (the amplitude of the sinusoidal wave is
increased until clipping occurs). The sinusoidal wave is then replaced with a square wave of the same
amplitude. The frequency is then increased until the maximum peak-to-peak output can no longer be maintained
(Figure 30). A square wave is used to allow a more accurate determination of the point at which the maximum
peak-to-peak output is reached.

test time
Inadequate test time is a frequent problem, especially when testing CMOS devices in a high-volume,
short-test-time environment. Internal capacitances are inherently higher in CMOS than in bipolar and BiFET
devices; hence, CMOS devices require longer test times than their bipolar and BiFET counterparts. The
problem becomes more pronounced with reduced power supply levels and lower temperatures.
