Short-circuit duration of less than 1 second. Average power must conform to the limit shown under the Absolute Maximum Ratings.
The minimum pulse width is the shortest pulse width at which the specified timing parameters are guaranteed.
The maximum switching frequency is the maximum signal frequency at which the specified timing parameters are guaranteed.
t PHL propagation delay is measured from the 50% level of the falling edge of the V Ix signal to the 50% level of the falling edge of the V Ox signal. t PLH propagation delay is
measured from the 50% level of the rising edge of the V Ix signal to the 50% level of the rising edge of the V Ox signal.
Channel-to-channel matching, rising, or falling edges is the magnitude of the propagation delay difference between any two channels of the same part when the
inputs are either both rising or falling edges. The supply voltages and the loads on each channel are equal.
Channel-to-channel matching, rising vs. falling edges is the magnitude of the propagation delay difference between any two channels of the same part when one
input is a rising edge and the other input is a falling edge. The supply voltages and loads on each channel are equal.
Part-to-part matching, rising, or falling edges is the magnitude of the propagation delay difference between the same channels of two different parts when the inputs
are either both rising or falling edges. The supply voltages, temperatures, and loads of each part are equal.
