Part Number: SN74LVC8T245

Hi,

Greetings of the day,

We follow the A to B operation mode in this project.

But, We can't get the signal flow(Pulse) from PORT A INPUT (INPUT from the C6678's GPIO pin) to PORT B's OUTPUT.

What is the problem with connections or other things?

Please provide us with a resolution on this thread, ASAP!

Warmest regards,

All supplies must have decoupling capacitors. Unused inputs must not float.

What is the problem you're seeing? What happens at the output pins?

Hi Michael.,

We used the Pull-down resister along with 1.8v GPIO(s) (from the MCU), After this connection we connected to the SN74LVC8T245.

It's working well.

Warmest regards,
