Description
The ’AC/’ACT299 is an 8-bit universal shift/storage register with TRI-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.
Features
- n ICC and IOZ reduced by 50%
