8-Input Universal Shift/Storage  Register with Synchronous  Reset and Common I/O Pins

The MC74AC323/74ACT323 is an 8-bit universal shift/storage register with3-state outputs. Its function is similar to the MC74AC299/74ACT299 with the exception of Synchronous Reset. 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.

• Common Parallel I/O for Reduced Pin Count
• Additional Serial Inputs and Outputs for Expansion
• Four Operating Modes: Shift Left, Shift Right, Load and Store
• 3-State Outputs for Bus-Oriented Applications
• Outputs Source/Sink 24 mA
• ′ACT323 Has TTL Compatible Inputs
