DESCRIPTION
The 74F299 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 parallel load. 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 and Q7 to allow easy serial cascading. A separate active-Low Master Reset is used to reset the register.
FEATURES
• 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
