ISO7842: TDDB of ISO78xx

Part Number: ISO7842

Hi,

Please tell me about TDDB of ISO78xx.

ISO7842: TDDB lifetime data is shown in Figure1 and Figure2 of the data sheet.
Data is stated only when Stress-voltage frequency = 60Hz.

Q1.Can you provide data at high frequencies other than 60Hz?

Q2.If it is higher than Stress-voltage frequency = 60Hz, does it affect the life of the device?
   ※ Can you comment such as shortening the life span or no change with 60 Hz time?

best regards
