Overview
The 74VHC164FT is a high-performance CMOS integrated circuit designed for digital data storage and transfer. As an 8-bit serial-in/parallel-out shift register, it is commonly used in applications requiring serial-to-parallel data conversion. Its high-speed operation and low power consumption make it a preferred choice in modern electronics. The IC is part of the 74VHC series, known for its compatibility with both CMOS and TTL logic levels. This versatility allows it to integrate seamlessly into various digital systems, from consumer electronics to industrial automation.
Structure and Working Principle
The 74VHC164FT consists of eight flip-flops connected in series, allowing data to be shifted through each stage with each clock pulse. Data is input serially and output in parallel, making it useful for expanding the number of output ports in microcontrollers. The IC operates with a single clock input and a master reset function, which clears all flip-flops when activated. Its CMOS technology ensures minimal power dissipation while maintaining high-speed performance, typically up to 100 MHz.
Key Features
The 74VHC164FT offers several advantages, including a wide operating voltage range (2.0V to 5.5V), making it suitable for both 3.3V and 5V systems. Its TTL-compatible inputs ensure easy integration with existing designs. Other notable features include low power consumption, high noise immunity, and robust ESD protection. These characteristics make it reliable for use in noisy industrial environments and battery-powered devices.
Application Areas
This IC is widely used in digital displays, LED matrix controllers, and serial data expansion for microcontrollers. It is also employed in communication systems for data buffering and signal processing. In industrial settings, the 74VHC164FT is utilized in automation controls, where reliable data transfer is critical. Its compact size and efficiency make it ideal for portable and space-constrained applications.
Maintenance and Precautions
To ensure longevity, avoid exposing the IC to static electricity by using proper handling techniques, such as grounded wrist straps. Operating beyond the specified voltage range can damage the device. Storage should be in a dry, static-free environment. When soldering, adhere to recommended temperature profiles to prevent thermal stress on the package.
B2B Procurement Guide
When sourcing 74VHC164FT ICs, verify the supplier's authenticity to avoid counterfeit components. Bulk purchases typically offer cost savings, with prices ranging from $0.50 to $2.00 per unit depending on quantity. Consider lead time and packaging options (e.g., tape and reel for automated assembly). Evaluate suppliers based on reliability, technical support, and compliance with industry standards.
