Channel-to-channel matching, rising or falling edges is the magnitude of the propagation delay difference between 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.
6
Channel-to-channel matching, rising vs. falling edges is the magnitude of the propagation delay difference between 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.
7
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.
8
Part-to-part matching, rising vs. falling edges is the magnitude of the propagation delay difference between the same channels of two different parts when one input
is a rising edge and the other input is a falling edge. The supply voltages, temperatures, and loads of each part are equal.
