CD74HCT164M96G4

高速CMOS逻辑8位串行输入/并行输出移位寄存器 High-Speed CMOS Logic 8-Bit Serial-In/Parallel-Out Shift Register

Description

The ’HC164 and ’HCT164 are 8-bit serial-in parallel-out shift registers with asynchronous reset. Data is shifted on the positive edge of Clock CP. A LOW on the Master Reset MR pin resets the shift register and all outputs go to the LOW state regardless of the input conditions. Two Serial Data inputs DS1 and DS2 are provided, either one can be used as a Data Enable control.
