74HC/LS164 2–6V High-Speed 8-Bit Serial-In Parallel-Out Shift Register IC | Low Power, Fast Switching, DIP/SOP Package | Xinbole

The 74HC/LS164 is a high-speed 8-bit serial-in, parallel-out shift register IC designed for efficient data storage and expansion in digital logic systems. Built using advanced High-Speed CMOS (HC) and Low-Power Schottky TTL (LS) technologies, it ensures fast switching performance, low power consumption, and strong noise immunity, making it ideal for modern embedded and control applications.

The LS version utilizes Schottky transistor technology to minimize propagation delay and improve switching speed, while the HC version provides ultra-low static current operation and a wide operating voltage range from 2V to 6V. This voltage flexibility offers a significant advantage over traditional TTL-only shift registers, allowing seamless integration in mixed-voltage digital systems with improved efficiency and reduced power loss.

With optimized internal architecture, the 74HC/LS164 delivers stable signal transfer, excellent thermal performance, and reliable long-term operation even in high-speed data applications. The device is available in both DIP and SOP packages, supporting easy prototyping as well as compact, high-density PCB designs.
