These Low-Power Schottky eight-bit universal registers feature 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. The clear function is synchronous, and a low level at the clear input clears the register on the next low-to-high transition of the clock.
- Multiplexed Inputs/Outputs Provide Improved Bit Density
- Four Modes of Operation:
- Hold (Store)
- Shift Left
- Shift Right
- Load Data
- Operates with Outputs Enabled or at High Z
- 3-State Outputs Drive Bus Lines Directly
- Can Be Cascaded for N-Bit Word Lengths
- Typical Power Dissipation … 175 mW
- Exceptionally Stable Shift (Clock) Frequency … 25 MHz
- Applications:
- Stacked or Push-Down Registers,
- Buffer Storage, and
- Accumulator Registers
