Part Number: TXS0206 Other Parts Discussed in Thread: TXB0104 , 我们使用了贵司的 一款芯片。TXS0206YFPR 。 由于某些原因,我们想换成txb0104,可是测试下来,访问TF卡失败。请问 ,这两颗芯片有什么区别?为什么不能替换? 实际我们测量发现TF卡的clk和cmd都能通过txb0104但是data线无数据,所以就不通。
Part Number: TXB0104 Dear TI members:
When I use TXB0104 in SPI(3.3V-1.5V),and put a 2k pull-dow resistor in IO,the Voh become lower and shake。
I found the reason that TXB0104 can't diver high load and it will reduce the level of the output in your datasheet…
