IC SHIFT/REGISTER STORE 20SOIC
The AC/ACT299 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. Product Highlights: ICC and IOZ reduced by 50% Common parallel I/O for reduced pin count Additional serial inputs and outputs for expansion Four operating modes: shift left, shift right, load and store 3-STATE outputs for bus-oriented applications Outputs source/sink 24 mA ACT299 has TTL-compatible inputs
