MC74HC164A

8位串行输入/并行输出移位寄存器 8−Bit Serial−Input/Parallel−Output Shift Register

High-Performance Silicon-Gate CMOS The is identical in pinout to the LS164. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The MC74HC164A is an 8-bit, serial-input to parallel-output shift register. Two serial data inputs, A1 and A2, are provided so that one input may be used as a data enable. Data is entered on each rising edge of the clock. The active-low asynchronous Reset overrides the Clock and Serial Data inputs.
