SN74LV244ATPW和SN74AHCT244PWR是否可以互相替代，5V供电，用于3.3V转5V，对延时要求不高。
SN74AHCT244比SN74LV244AT功能有所升级：
Larger voltage range (2V to 5.5V),
shorter average propagation delay (9ns)
对延时要求不高的话，二者可以互相替代。
我看价格SN74AHCT244更低，是否因为其输出电流更小和静态电流更大？其他性能确实相对更优
以及您说的这个电压范围，我看二者都一样呀
Taylor 说：Larger voltage range (2V to 5.5V),
有时价格不仅和性能有关，还和供货等其他因素相关。
具体参数请以数据手册为准。
总之对延时要求不高的话，二者可以互相替代。
