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 with 3-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
⢠â²ACT323 Has TTL Compatible Inputs
