Design a Custom BoardAbout This Component
BCD-to-7-segment latch/decoder/driver IC for single-digit LED or LCD displays. Decodes 4-bit binary-coded decimal inputs and outputs to control seven segments plus decimal point. Features internal latches, blanking function, and configurable output polarity for common-cathode or common-anode displays. Typical applications include digit multiplexing in counters, timers, and numerical displays.
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.
