16位串行/并行-IN ，串行输出移位寄存器 16-Bit Serial/Parallel-In, Serial-Out Shift Register
General Description
The 74F676 contains 16 flip-flops with provision for synchronous parallel or serial entry and serial output. When the Mode M input is HIGH, information present on the parallel data P0–P15 inputs is entered on the falling edge of the Clock Pulse CP input signal. When M is LOW, data is shifted out of the most significant bit position while information present on the Serial SI input shifts into the least significant bit position. A HIGH signal on the Chip Select CS input prevents both parallel and serial operations.
