1 / 6 page © 1999 Fairchild Semiconductor Corporation DS009515 www.fairchildsemi.com April 1988 Revised August 1999 74F299 Octal Universal Shift/Storage Register with Common Parallel I/O Pins General 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 load data. The parallel load inputs and flip-flop outputs are multiplexed to reduce the total number of package pins. Additional outputs, Q0– Q7, are provided to allow easy serial cascading. A separate active LOW Master Reset is used to reset the register. Features s Common parallel I/O for reduced pin count s Additional serial inputs and outputs for expansion s Four operating modes: shift left, shift right, load and store s 3-STATE outputs for bus-oriented applications s Guaranteed 4000V minimum ESD protection Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
