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?
【Background】
・Customer is using Vcc:+15V and GND:-15V
・When -15V power supply is damage by customer accident, they worry about Vcc move Vcc<GND for the moment.
Best regards,
Satoshi
