54F299中文资料Octal Universal Shift/Storage Register with Common Parallel I/O Pins数据手册TI规格书

描述 Description

General Description
The ’F299 is an 8-bit universal shift/storage register with TRI-STATEÉ 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, Q0–Q7, are provided to allow easy serial cascading. A separate active LOW Master Reset is used to reset the register.
