Design a Custom BoardAbout This Component
8-bit addressable latch decoder with individual output latches controlled by address inputs A0-A2 and a data input. Each of 8 outputs can be independently set or cleared by applying the desired address and data level. Operates at 2V to 6V supply. Commonly used for control signal generation, output expansion, and addressable switching applications in digital systems.
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.
