When a hold time is specified between an input and a clock, the hold time

is the time in nanoseconds from the 1.4 Volt point of the clock to the 1.4 Volt

point of the input.

Output propagation delay time is the time in nanoseconds from the 1.4

Volt point of the reference signal to the 1.4 Volt point of the output.

Maximum and minimum output propagation delays are measured with a

50 pF load on all the outputs.
