TXE8124-Q1: TXE8124

Part Number: TXE8124-Q1


Hi, TI Experts

Question 1: as picture shows below , Is there Clamp Diode between GPIO Pin to VCC ?

( Does the IC has the ability to clamp the input voltage to VCC+04V?)

Question 2:

If all the IC GPIOs are used for GPO output function , Does the INT pin make sense?  Is the INT pin floating ?

Thanks !

    I measured the P00 pin to VCC on a multi-meter with the diode function and got 1.7V. 

    The recommended operating conditions in the datasheet suggest that VIH should be max VCC and not over.

    You can have /INT pin floating as this pin is an open-drain output.
