Description

The 74AC299 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 are provided for flip-flops Q0, Q7 to allow easy serial
cascading. A separate active LOW Master Reset is used to reset the register.
