SN74LS299N | Texas Instruments
Shift register, 4.75 V, 5.25 V, PDIP20
Shift register, SN74LS299N, Texas Instruments
The SN74LS299N is a schottky TTL eight-bit universal 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, SO 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.
Features
- Multiplexed inputs/outputs provide improved bit density
- Operates with outputs enabled or at high Z
- 3-State outputs drive bus lines directly
- Can be cascaded for N-bit word lengths
Applications
- Stacked or push-down registers
- Buffer storage
- Accumulator registers
