About buffer for AM4379
spruhl7i技术手册(AM437x and AMIC120 ARM® Cortex™-A9 Processors Technical Reference Manual)推荐在PORZ管脚和nRESETIN_OUT管脚添加一个open-drain的buffer,是否可以用非开漏的buffer,比如SN74LV1T125。谢谢!
Shine:
如果这个管脚作输出的话,要用开漏buffer,手册里有对nRESETIN_OUT管脚的说明:
The nRESETIN_OUT output buffer is configured as an open-drain; consequently, an external pull-up resistor is required.

谢谢您的回复。想确认一下,这两个管脚间必须用开漏的buffer吗?

是的,需要用开漏buffer。
