OPERATION
LTC6994-2 Functionality
Figures 5 details the basic operation of the LTC6994-2
when configured for noninverting operation (POL = 0). As
before, a rising edge on the IN pin initiates the timing and,
if IN remains high, OUT will transition high after t_DELAY .
Unlike the LTC6994-1, falling edges are delayed in the
same way. When IN transitions low, OUT will follow after
t_DELAY .
If the input doesn’t remain high or low long enough for OUT
to follow, the timing will restart on the next transition.
Also unlike the LTC6994-1, the output pulse width can
never be less than t_DELAY . Therefore, the LTC6994-2 can
generate pulses with a defined minimum width.
Figure 6 details the operation of the LTC6994-2 when the
output is inverted (POL = 1).
