74F299 Octal Universal Shift/Storage Register 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: Order Number 74F299SC 74F299SJ 74F299PC Package Number M20B M20D N20A Package Description 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300 Wide 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 20-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel.
