Dt Sheet. The output drivers feature a high pulse current buffer stage. Please contact your International Rectifier sales representative for further information. Higher MSL ratings may be available for the specific package types listed here. All voltage parameters are absolute voltages referenced to COM. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions.

For proper operation the device should be used within the recommended conditions. The VS offset rating is tested with all supplies biased at 15V differential. Symbol Definition Min. Please refer to the Design Tip DT97 -3 for more details. Even though the IRSS has been shown able to handle these negative VS transient conditions, it is highly recommended that the circuit designer always limit the negative VS transients as much as possible by careful PCB layout and component use.

In contrast, such activation was either very weak or nil when cells were treated by IFN-beta or tumor necrosis factor-alpha TNF-alpha , despite the fact they both efficiently induce de novo synthesis of the short-lived IRF-1 in L cells. In fact, efficient activation of the IRF-E apparently requires an event in addition to de novo IRF-1 induction, which can be elicited by NDV even in the presence of protein synthesis inhibitor, cycloheximide. Hence our results suggest the importance of IRF-1 synthesis and post-translational modification event s , possibly phosphorylation for the efficient activation of IRF-Es, which are otherwise under negative regulation by IRF National Center for Biotechnology Information , U.
