All characteristics are measured with a 0.33-mF capacitor across the input and a 0.1-mF capacitor across the output. Pulse-testing
techniques maintain TJ as close to TA as possible. Thermal effects must be taken into account separately.
(2)
This specification applies only for dc power dissipation permitted by absolute maximum ratings
