The internal circuitry does not allow the transition from an
S4/S5 (suspend to disk/soft off) state to an S3 (suspend to
RAM) state; however, it does allow the transition from S3 to
S4/S5. The only ‘legal’ transitions are from an active state
(S0, S1) to a sleep state (S3, S5) and vice versa.
NOTE: Combination Not Allowed.

Functional Timing Diagrams
Figures 4 (EN5 = low), 5 (EN5 = high), and 6 are timing
diagrams, detailing the power up/down sequences of all the
outputs in response to the status of the sleep-state pins (S3,
S5), as well as the status of the input ATX supply. Not shown in
these diagrams is the deglitching feature used to protect
against false sleep state tripping. Both S3 and S5 pins are
protected against noise by a 2µs filter (typically 1–4µs). This
feature is useful in noisy computer environments if the control
signals have to travel over significant distances. Additionally, the
S3 pin features a 200µs delay in transitioning to sleep states.
Once the S3 pin goes low, an internal timer is activated. At the
end of the 200µs interval, if the S5 pin is low, the ISL6505
switches into S5 sleep state; if the S5 pin is high, the
ISL6505 goes into S3 sleep state.
The shaded column in Figures 4 and 5 highlights the
difference on the 5VDLSB and 5VDL pins for the two EN5
states.
