74ACT323PC集成电路（IC）的移位寄存器规格书PDF中文资料

General Description

The ACT323 is an 8-bit universal shift/storage register with 3-STATE outputs. Parallel load inputs and flip-flop outputs are multiplexed to minimize pin count. Separate serial inputs and outputs are provided for Q0 and Q7 to allow easy cascading. Four operation modes are possible: hold (store), shift left, shift right and parallel load.
