74F323

74F323 Octal Universal Shift/Storage Register April 1988 Revised August 1999 74F323 Octal Universal Shift/Storage Register with Synchronous Reset and Common I/O Pins General Description The 74F323 is an 8-bit universal shift/storage register with 3-STATE outputs. Its function is similar to the 74F299 with the exception of Synchronous Reset. Parallel load inputs and flip-flop outputs are multiplexed to minimize pin count. Separate serial inputs and outputs are provided for Q0 and Q7 to allow easy cascading. Four operation modes are possible: hold (store), shift left, shift right and parallel load. 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 Ordering Code: Order Number 74F323SC 74F323PC Package Number M20B N20A Package Description 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300 Wide 20-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel.
