AiP74HC/HCT573是一个带三态输出的8位D型锁存器。该器件具有锁存使能(LE) 和输出使能(OE)。当LE为高电平时，输入端的数据进入锁存器中。在这种情况下，锁存器是透明的，每次其相应的D输入更改时，锁存器输出都会更改。当LE为低电平时，锁存器存储LE下降沿前一个建立时间的输入端信息。OE上的高电平使输出...
具有三态输出的八路透明D型锁存器 SN74HCT573产品信息: 这些八进制透明d型锁存器具有专为驱动高电容或相对低阻抗负载而设计的三态输出。HCT573器件特别适用于实现缓冲区寄存器、I/O端口、双向总线驱动程序和工作寄存器。 当锁存使能(LE)输入高时,Q输出响应数据(D)输入。当LE低时,输出被锁存以保留在D输入处设置的...

没仔细看标题。楼主说的是HC和HCT之间的区别，不是373和573的区别
The 74HC573; 74HCT573 is an 8-bit D-type transparent latch with 3-state outputs. The device features latch enable (LE) and output enable (OE) inputs. When LE is HIGH, data at the inputs enter the latches. In this condition the latches are transparent, a latch output will change ...
