Description

The 74ACT323PC is an 8-bit universal shift/storage register with 3-STATE outputs. Parallel load inputs and flip-flop outputs of the 74ACT323PC 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.
