SN74LS299N

The SN74LS299N is an 8-bit universal shift/storage register manufactured by Texas Instruments. This component is designed for applications requiring flexible data handling, offering four modes of operation: hold (store), shift left, shift right, and load data. It features multiplexed inputs/outputs for improved bit density and operates within a supply voltage range of 4.75V to 5.25V.

Key electrical characteristics include a maximum clock frequency of 25 MHz and a propagation delay between 10-50 ns. The device supports a wide output current capability, with a high-level output current of -2.6 mA and a low-level output current of 24 mA. Its maximum supply current is 53000 µA.

The SN74LS299N is housed in a 20-PDIP package and is designed for through-hole mounting. It operates within an ambient temperature range of 0°C to 70°C. The device's outputs are tri-state, allowing them to drive bus lines directly or be placed in a high-impedance state. This register can be cascaded to achieve longer word lengths.

Applications for the SN74LS299N include stacked or push-down registers, buffer storage, and accumulator registers. Its versatility makes it suitable for various digital logic designs where efficient data manipulation is required.
