74LVC594A是带存储寄存器的8位串行输入/串行或并行输出移位寄存器。移位和存储寄存器上都提供单独的时钟和复位输入。
输入可通过3.3 V或5 V器件进行驱动。该特性允许在混合3.3 V和5 V环境中使用该器件。
该器件完全针对使用IOFF的局部掉电应用设计。IOFF电路可禁用输出,防止掉电时破坏性回流电流通过该器件。
移位寄存器具有用于级联的一个串行输入(DS)和一个串行输出(Q7S)。数据在SHCP输入正向跃迁时移位。移位寄存器中的数据在STCP输入正向跃迁时会被传输到存储寄存器。如果两个时钟连在一起,则移位寄存器将总是比存储寄存器超前一个时钟脉冲。两个寄存器复位针脚(SHR和STR)的其中之一上的低电平将清零相应的寄存器。
