Other Parts Discussed in Thread: ESD351
We are working with SN74LVC2G34 as a buffer for the TxD and RxD UART signals from the MCU to drive a cable between two boards separated by about 12 inches. The voltage is about 3.3V and the data rate is 250kHz. When hot inserting the cable the buffer is damaged. Would use suggest a different device to drive the cable? They currently have a TVS diode with a clamping voltage of 7.5V, could this be resolved by using a lower clamping voltage device such as ESD351?
