The CD54HC299FX is an 8-bit universal shift register from Harris Corporation (now Intersil). It is part of the High-Speed CMOS (HC) logic family, offering high speed and low power consumption. This versatile device can perform serial-to-serial, serial-to-parallel, parallel-to-serial, and parallel-to-parallel data transfers, making it suitable for a wide variety of digital logic applications.

Applications:

• Serial data communication
• Data storage and retrieval
• Digital delay lines
• Sequence generators
• Keyboard and display scanning

Features:

• 8-bit parallel input/output: Allows for parallel data transfer.
• Serial input/output: Enables serial data communication.
• Synchronous parallel loading: Permits loading of all 8 bits simultaneously.
• Shift right and shift left capability: Provides flexibility in data manipulation.
• Three-state outputs: Facilitates bus-oriented systems.

Benefits:

• Versatile data manipulation: Supports multiple data transfer modes.
• High-speed operation: HC logic family provides fast switching speeds.
• Low power consumption: CMOS technology minimizes power dissipation.
• Easy integration: Compatible with other HC logic devices.
• Wide operating voltage range: Operates from 2V to 6V.

Additional Details:

The CD54HC299FX is typically supplied in a 20-pin Flatpack package, suitable for military and aerospace applications due to its rugged construction and wide temperature range. The device has a typical propagation delay of around 15ns at 5V, allowing for high-speed data processing. The control inputs determine the mode of operation: shift right, shift left, parallel load, or hold. The three-state outputs can be disabled to allow multiple devices to share a common bus. This makes the CD54HC299FX a highly flexible and reliable component for various digital systems requiring serial or parallel data handling.
