Hi team,
my customer is using the SN74TVC3306 now, we have two items want to double check with you.
1. whether the A side is the Vref.
2. if the Vgate-VA is below 0.6v, what's the risks?
Thanks.

Hi team,

In the circuit shown, VREF is on the A side. The device is symmetrical, so you could exchange all A and B signals.
The clamping relies on the first transistor being partially on, i.e., on the gate being a threshold voltage above VREF.
Hi Ladisch,
For the item 2: i still not quite understand the risks if the Vgs is larger than Vref+0.6v, for example, it's Vref+0.3v or 0.5v. Thanks.
Hi Xiao,
The risk is, that the application won't work as expected and that the switching times might be slower than expected.
Can you explain what you are trying to do?
Best regards,
Ambroise
