Part Number: TCA6424A Hi,
A question about TCA6424A IO pin voltage, if 5V rail on I/O pins as pull-up, but 3.3V is used on both Vcc and Vccp pins. will it have leakage current to Vcc and Vccp pins from 5V at I/O pins?
this statement on data sheet, not…
Part Number: TCA6424A Hi Team,
Can you provide the junction-to-case bottom /junction-to-board and the maximum junction temperature of the IC?
I found discussion for the max junc temp but it is more on estimation, please see link below.
