Notes
1. TXD is LOW. Short-circuit protection provided for slew rates up to 5 V/µs for voltages above +30 V.
2. Short-circuit applied when TXD is HIGH, followed by TXD switched to LOW.
3. In accordance with
“IEC 60747-1”.
An alternative definition of virtual junction temperature is:
T
vj
= T
amb
+ P
d
×
R
th(vj-a)
, where R
th(vj-a)
is a fixed value to be used for the calculation of T
vj
. The rating for T
vj
limits
the allowable combinations of power dissipation (P
d
) and ambient temperature (T
amb
).
