I have a question ADM3051 Maximum Ratings.
In customer's usage state, -1.3V/40ns is impressed on a TxD terminal and a RS terminal.
ADM3051 Maximum Ratings
The under chute hours are 6ns and instant-like.When mean voltage is considered as a cycle signal of (=100kHz) for 10 μs.The next is very slight for for 1.3 V x 6 ns/10 μs = 0.78 mV.
A measure is difficult and when it's no problem, I want you to tell me...
Table 1 provides an Absolute maximum rating for the TxD, RxD pins.
This is a DC rating, which is different from the transient overvoltage that you describe.
How often does this pulse happen? On the falling edge of all bits?
Operation beyond the maximum operating conditions for extended periods may affect product reliability.
Thank you for your answer.
