(1) The typical continuous current rating is limited by V_OL= 0.4V. Whereas, absolute maximum operating continuous current may be limited
by the Thermal Performance parameters listed in the Dissipation Rating Table and other Reliability parameters listed in the
Recommended Operating Conditions Table.
(2) Refer to the Absolute Maximum Ratings Table for T_J dependent absolute maximum GND-pin current.
(3) Rise and Fall propagation delays, t_PHL and t_PLH, are measured between 50% values of the input and the corresponding output signal
amplitude transition.
(4) Guaranteed by design only. Validated during qualification. Not measured in production testing.
(5) Not rated for continuous current operation – for higher reliability use an external freewheeling diode for inductive loads resulting in more
than specified maximum free-wheeling. diode peak current across various temperature conditions
