8-Input Universal Shift/
Storage Register with
Common Parallel I/O Pins
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
′ACT299 Has TTL Compatible Inputs
