CMOS low power dissipation. The VHCT245A is intended for bidirectional asynchronous communication between data busses. The direction of data transmission is determined by the level of the T/R input. The enable input can be used to disable the device so that the busses are effectively isolated...

另外一个问题就是如果VCC接地,VCC=0的话,此时如果还有输入信号,是否会导致有输出的现象,像我们的有些逻辑芯片,datasheet中如果给出Ioff这个参数,说明此器件支持Ioff特性,即即使VCC=0,但输出是高阻抗。 那么VCC=0,是否可以允许有输入信号呢?这个也要看芯片的数据手册,看输入端和供...

从二者的datasheet上来看,SN74AHCT245更符合你的要求,这款芯片接受TTL电平输入,也就是说5V供电时,3.3V LVTTL输入是没问题的,并且输出Voh和Vl 是符合5V CMOS电平标准,相当于实现了一个3.3V 到5V的一个升压转换功能。 看了下ABT541这款,虽然也注释了可以接受TTL电平输入,但看Voh和Vol 的范围,是达不到5V CMOS...
