Is there in the datasheets or product design guides an explanation on the maximum I/O sink currents that the Xavier NX and Nano per I/O pin can handle?
By looking at the Xavier NX and Nano dev kit schematics I’ve noticed the following:
- Xavier NX dev kit = POWER_EN signal buffered with SN74LV1T125. This buffer has an output drive of 8mA at 5V.
- Nano dev kit = POWER_EN signal buffered with 74LVC1G126. This buffer has an output driver of 32mA at 4.5V.
Is this a problem if the Xavier NX and Nano modules are used interchangeable on the dev kits?
We are trying to establish commonality among components on a custom carrier and knowing the risks on I/O sink currents will be helpful.
