onsemi Shift Registers 74F322PC

The 74F322PC is an 8-bit octal shift register that supports both serial and parallel loading with 3-STATE parallel outputs and a bi-state serial output. It features multiplexed parallel I/O ports to reduce pin count and operates with four synchronous modes: hold, shift right with serial entry, shift right with sign extend, and parallel load. The device includes an asynchronous Master Reset (MR) input that clears the register regardless of clocked operation. The shift register is housed in a 20-lead Plastic Dual-In-Line Package (PDIP) and is designed for applications requiring efficient data handling and manipulation. It operates with a maximum clock frequency of 70 MHz and has propagation delays ranging from 3.5 ns to 11 ns, depending on the specific operation. The device is suitable for bus applications due to its 3-STATE outputs and can be ordered in tape and reel format for automated assembly processes.
