Product Overview: 74F299 from NXP Semiconductors
The 74F299 is a high-performance, 8-bit shift/storage register with 3-state outputs, manufactured by NXP Semiconductors. This integrated circuit is designed to be used in a wide range of applications that require the temporary storage of data or the reordering of data bits, making it an essential component in digital systems.
The 74F299 register features an input and output capability on both the register's right and left sides, enabling parallel or serial shifting in either direction. The device operates on a 5V power supply, which is typical for many standard TTL devices, and it is compatible with most logic families, making it versatile for integration into various digital systems.
One of the key attributes of the 74F299 is its 3-state outputs. This feature allows the outputs to assume a high impedance state in addition to the conventional logic levels, providing the ability to disconnect the outputs from the bus lines, which is particularly useful in creating bus-oriented systems.
Key Features
- 8-bit parallel input/output
- Shift right/shift left capability
- 3-state outputs for bus-oriented applications
- Hold (storage) capability
- Direct overriding clear
- Serial input/output for both shift right and shift left
- Operates at 5V power supply
- High-speed performance
The 74F299 also includes a direct clear function, which enables the register to be cleared, setting all outputs to a low level, regardless of other input conditions. This is particularly useful for initializing the register during power-up or other reset conditions.
The device's high-speed performance is suitable for applications that require fast data manipulation and throughput, ensuring that it can keep up with the demands of modern digital systems. Whether used in microprocessor systems, communication systems, or data manipulation tasks, the 74F299 from NXP Semiconductors offers reliable and flexible performance for designers and engineers.
