NOTES
1
Absolute maximum ratings are limiting values, to be applied individually, and beyond which the service ability of the circuit may be impaired. Functional operability
is not necessarily implied. Exposure to absolute maximum rating conditions for an extended period of time may affect device reliability.
2
Maximum junction temperature should not exceed +175
°
C for ceramic packages, +150
°
C for plastic packages. Junction temperature can be calculated by:
t
= PD (

JA
) +t
A
= PD (
θ
JC
) +t
C
where:
PD = power dissipation
θ
JA
= thermal impedance from junction to air (

θ
JC
= thermal impedance from junction to case (

C/W)
t
A
