产品概述
The SN74LS299N is an universal Shift/Storage Register features multiplexed inputs/outputs to achieve full eight-bit data handling in a single 20-pin package. Two function-select inputs and two output-control inputs can be used to choose the modes of operation listed in the function table. Synchronous parallel loading is accomplished by taking both function-select lines, S0 and S1, high. This places the three-state outputs in a high-impedance state, which permits data that is applied on the input/output lines to be clocked into the register. Reading out of the register can be accomplished while the outputs are enabled in any mode. A direct overriding input is provided to clear the register whether the outputs are enabled or off.
- Multiplexed inputs/outputs provide improved bit density
- Hold (Store) operating mode
- Shift left operating mode
- Shift right operating mode
- Load data operating mode
- Operates with outputs enabled or at high Z
- 3-state Outputs drive bus lines directly
- Can be cascaded for N-bit word lengths
