After the reception of a pulse current

(100nA<IPD<100μA) at pin PD until a next pulse can

be detected. It is to note that a higher input current

pulse may lead to a secondary output pulse and thus

a longer recovery time.

Current pulse width at pin PD necessary to generate

an output pulse at pin OUT. The input sensitivity is de-

pendent on the input current pulse width (refer to the

section Applications and Other Parameters).
