1、位移位存储总线寄存器CD4094中文资料CD4094是带输出锁存和三态控制的串入/并出高速转换器，具有使用简单、功耗低、驱动能力强和控制灵活等优点。CD4094的引脚图及引脚描述其中(1)脚为锁存端，(2)脚为串行数据输入端，(3)脚为串行时钟端。(1)脚为高电平时，8位并行输出口Q1Q8在时钟的上升沿随串行输入而变化；(1)脚为低电平时，输出锁定。利用锁存端可方便地进行片选和级联输出控制。(15)脚为并行输出状态控制端，(15)脚为低电平时，并行输出端处在高阻状态，在用CD4094作显示输出时，可使显示数码闪烁。(9)脚QS、(10)脚QS是串行数据输出端，用于级联。QS端在第9个串行时钟的
2、上升沿开始输出，QS端在第9个串行时钟的下降沿开始输出。当CD4094电源为5V时，输出电流大于32MA，灌电流为1 MA。串行时钟频率可达25MHZ。 CD4094引脚图CD4094真值表：ClockOutput EnableStrobeDataParallel Outputs 并行输出Serial Outputs 串行输出Q1QNQS (Note 1)Q S0XX三态三态Q7不变0XX三态三态不变Q710X不变不变Q7不变1100QN-1Q7不变1111QN-1Q7不变111不变不变不变Q7CD4094内部电路方框图Absolute Maximum Ratings 绝对最大额定值：Supp
