8Input 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
