Input Trg
Parameter
Output
L
Description
A positive edge (0 to 1 transition) at input Trg (Trigger)
triggers the on-delay time T
A negative edge (1 to 0 transition) at input Trg
(Trigger) triggers the off-delay time T
T is the time after which the output is set hi (output
H
signal transition 0 to 1).
T is the time after which the output is reset ( output
L
signal transition 1 to 0).
Retentivity:
/ No retentivity
R The status is retentive.
