Part Number: LM2901-N Please let me know about the case of Vcc<GND transient condition below.
①When transient time is very short(ex, 10ns), is this possibility to damage?
②If no damage, is there tolerance spec of "GND-Vcc" and transient time?

we wanna use the LM339 in our design. The junction temperature of this device is quite limited and we wondering if the Tjmin (0degC…
National Semiconductor designed the LM2901-N for 85 °C. This device exists to support old National customers, so the specification was never changed, even if TI does more rigorous tests.
Hello David,
For low-power devices like comparators and op-amps, which do not usually dissipate much heat, ambient temp and junction temp tend to be used interchangeably.
The LM2901-N datasheet, which was the original National Semiconductor datasheet…
Part Number: LM339-N The LM339-N data sheet (revised December 2014) page 7 appears to have full temperature values but they are not listed as such.
Please confirm that the marked section (link below) is over full temperature.

Hi Vladimir,
I think the major cause here is an improper layout. Keep in mind that when a short circuit occurs dozens of Ampères will flow through R9 and all involved "230V N" connections:
So all the different "230V N" nodes in your schematic can…
