General: Triggered by the input's rising edge (input
pulse width 10 ns, min .), a pu lse of specified wid th
will be generated at the output with a propagation
delay of 5 ± 2 ns (7 ± 2 ns, for inverted output). High-
to-low transitions will not trigger the unit. Designed
for output duty-cycle less than 50%.
