Hi all,
There are two questions about the failure mode when a breakdown due to overvoltage of DC 26.4 V exceeding the maximum absolute rating occurs on the RS-232C bus of TRS3237E.
1. What about the situation of destruction occurred about the driver and receiver of RS - 232C bus ?
short to VCC or GND, or open state, etc.?
2. When breakdown occurs, is there a possibility that excessive voltage or current will flow in PINs on the TTL side?
Is there a possibility that the device connected to the TTL side is destroyed depending on the failure situation?
Regards,
Toshi
