Hi Team,
I have a customer with a couple questions related to the post on driving the inputs above Vcc - the question is around driving the inputs above the abs max voltage, while the input current ratings are observed.
This is commonly stated in the abs max section as being OK, but isn't mentioned in the recommended operating conditions section. With this, here are the two questions:
- Are the outputs deterministic when the inputs are driven above the rail (assuming the current limit is respected)?
- Is there any degradation to lifetime when driving inputs above the rail (assuming the current limit is respected)?
This is specifically for the inputs on the SN74AHC14-Q1, but I believe would apply to all devices with this condition.
Regards,
