Hi ti,
需要将串口的3.3V CMOS TX信号转为1.8V或2.5V电平输入到SOC里;
请问用SN74LVC1G126的话,VCC连接2.5V时,TX信号输入到A口,是否能在Y实现2.5V的信号输出?
VCC连接1.8V时,TX信号输入到A口,是否能在Y实现1.8V的信号输出?

您好,
datasheet 没有给出2.5V和1.8V供电电压下的输出电平,但是您可以根据下面FAQ进行估算:
What method is best used for estimating specification values between those given in the datasheet?
