CX74HC164这些8位移位寄存器具有门控串行输入和异步清除(CLR)输入。门控串行(A和B)输入允许对输入数据进行完全控制;任一输入处的低电平禁止输入新数据,并在下一个时钟(CLK)脉冲时将第一个触发器重置为低电平。一个高级输入启用另一个输入,然后确定第一个触发器的状态。当CLK为高或低时,串行输入端的数据可以改变,只要满足最小设置时间要求。时钟发生在CLK从低电平到高电平的转换上。

产品概述 返回TOP
These 8-bit shift registers feature AND-gated serial inputs and an asynchronous clear (CLR) input. The gated serial (A and B) inputs permit complete control over incoming data; a low at either input inhibits entry of the new data and resets the first flip-flop to the low level at the next clock (CLK) pulse. A high-level input enables the other input, which then determines the state of the first flip-flop. Data at the serial inputs can be changed while CLK is high or low, provided the minimum setup time requirements are met. Clocking occurs on the low-to-high-level transition of CLK.
The CX54HC164 is characterized for operation over the full military temperature range of –55℃ to 125℃. The CX74HC164 is characterized for operation from -40℃ to 85℃.
