8位并行输出串行移位寄存器 8-BIT PARALLEL-OUT SERIAL SHIFT REGISTERS

Description

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 set-up time requirements are met. Clocking occurs on the low-to-high-level transition of CLK.
