8-BIT SHIFT REGISTER PARALLEL LOAD 16-SOIC

Design a Custom BoardThe SN74HC166 is an 8-bit parallel-load shift register with serial input, enabling parallel-to-serial data conversion. Operating from 2V to 6V with 13ns typical propagation delay and ±4mA output drive, it features synchronous loading, direct clear override, and low power consumption (80µA max). Ideal for expanding microcontroller I/O capabilities and serial data conversion applications.
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.
