FACT DATA

"
The MC74AC299/74ACT299 is an 8-bit universal shift/storage register
with 3-state outputs. Four modes of operation are possible: hold (store), shift left,
shift right and load data. The parallel load inputs and flip-flop outputs are multiplexed
to reduce the total number of package pins. Additional outputs are provided for
flip-flops Q0, Q7 to allow easy serial cascading. A separate active LOW Master
Reset is used to reset the register.
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
