When the 3.3V is apply to ADM0302, I have (One Time on two) the transmit output that rise up then go down à -6.6V. This cause an unknown charater on my RS232 link.

Yellow = TX, RED=VCC at power up

In this case, on same component I have not unknown character. The design respect the data sheet external component.
