The TC74VHC299FT from Toshiba is an 8-bit Universal Shift Register fabricated with silicon gate CMOS technology. It is designed for high-speed operation and low power consumption, making it suitable for a wide range of digital applications.

Applications:

• Serial-to-parallel data conversion
• Parallel-to-serial data conversion
• Data storage and manipulation
• Digital delay lines
• Microprocessor systems

Features:

• High-speed operation: tpd = 4.0 ns (typ.) at VCC = 5V
• Low power consumption: ICC = 4.0 μA (max) at Ta = 25°C
• Wide operating voltage range: VCC = 2V to 5.5V
• 8-bit parallel input/output capability
• Serial input and output for shift register operations
• Three-state outputs for bus interfacing
• Direct clear input

Benefits:

• Fast data transfer rates due to high-speed operation.
• Energy efficient operation, ideal for battery-powered devices.
• Flexible integration into various systems with a wide operating voltage range.
• Versatile data handling with both serial and parallel input/output options.
• Easy interfacing with microprocessors and other digital circuits via three-state outputs.
• Quick reset capability using the direct clear input.

Additional Details:

The TC74VHC299FT features four modes of operation: parallel load, shift right, shift left, and hold. The mode is selected by two mode control inputs (S0 and S1). The register has a direct clear input (CLR) that resets all flip-flops to a low state. The three-state outputs (Q0-Q7) are controlled by an output enable input (OE). When OE is high, the outputs are in a high-impedance state. The device is available in a TSSOP package, allowing for high-density mounting on PCBs. The operating temperature range is -40°C to +85°C.
