The 74AC299PC from Texas Instruments is an 8-bit universal shift/storage register designed for bus-oriented applications. It features 3-STATE outputs that can source and sink 24mA, reducing pin count through common parallel I/O.
This device supports four distinct operating modes: hold (store), shift left, shift right, and parallel load. Data is loaded via parallel inputs, and flip-flop outputs are multiplexed to these same pins. Additional serial inputs and outputs are provided for easy cascading to create longer shift registers.
A separate active LOW Master Reset (MR) input allows for immediate resetting of the register, overriding other control inputs. All state changes are initiated by the rising edge of the clock signal, provided setup and hold times are met.
The 74AC299PC is available in a 20-lead PDIP package suitable for through-hole mounting. It is also available in tape and reel packaging.
