如果可以的话，原理图需要如何连接？
您好，
是的，支持推挽的自动双向转换应用：
在 datasheet 9.2 Typical Applications 章节有接线图。
SPI 接口应用的话，建议使用SN74AXC4T774 (Q1) / TXB0104 (Q1) 或TXU0304 (Q1) 3+1 Bit，这几个器件的鲁棒性更好一些。
[FAQ] Are there voltage level translation / level shifter device recommendations for the industry standard interfaces like GPIO, SPI, UART, I2C, MDIO, RGMII, I2S etc?
