APPLICATION CIRCUIT
APPLICATION HINTS:
For 12V supply and 8
maximum power dissipation is about 1W.
Assumming that max ambient temperature is
70 C. Required thermal resistance of the device
and heat dissipating means must be equal to (150
- 70)/1 = 80 C/W.

Junction to pin thermal resistance of the package
is about 15 C/W. That means external heat sink
of about 65 C/W is required.
Cu ground plane of PCB can be used as heat dis-
sipating means.
Stand-By switches must be able to discharge C
current.
