Design a Custom BoardAbout This Component
8-bit parallel-in/serial-out shift register with selectable parallel load or serial input modes. Features clock enable and master reset controls, operates from 2.0V to 6.0V supply, and includes TTL-compatible input levels (HCT variant). Suitable for data conversion, display drivers, and synchronous serial expansion applications.
Package: SOIC-16 (3.9×9.9mm) · 16 pins
Why does this need a breakout?
The 1.27mm pin pitch on this 16-pin package makes hand-soldering impractical and breadboard mounting impossible. A breakout board brings the pins to standard 2.54mm spacing, enabling quick prototyping of RS-232/RS-485 transceivers, ADCs, and line drivers without requiring surface-mount soldering skills or PCB fabrication.
