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?…
Other Parts Discussed in Thread: LM2901 , LM2901-N , LM339 I am now sourcing LM2901, but can only found LM2901-N(LM2901MX). Is it a direct replacement?
Hello Bea,
The LM139 is the -55 to +125C version (Military).
The LM239A or LM239-N (ex-National) is the -25 to 85C version.
The LM2901, LM2901V or LM2901-N (ex-National) is the -40 to +125C version.
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.
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…
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…
Hello Todd,
Are you are referring to the National Semi version (-N), or the TI version?
I will respond for the National version..
No. The LM2901 (or LM139/239/339/3302) does NOT have ESD diodes on the inputs.
This is why it only has a 600V ESD rating…
