Hi Logic team

Gerald,
This can be inferred from the absolute maximum rating entries for VI.
In this case, the entry is -0.5V to VCC+0.5V. This indicates that both the diode to ground and VCC will start conducting around 500mv above VCC and below ground.

Wade

Hi Wade

Thank you for your reply.

1. Can we get information Which is Clamp diode Voltage at the AHC and HD of TI Logic family as a picture above ?
2. Can we get information and document Derating grahp each temperature(example -40C, 25C, 70C, 125C)

If you have any question contact me anytime.

Best Regards
