Design a Custom BoardAbout This Component
Dual 2-to-4 line decoder/demultiplexer in 16-SSOP package. Each decoder features two active-low enable inputs and four active-low outputs, capable of selecting one of four lines based on two address inputs. Operates on 5V logic levels with HCT-series TTL compatibility, suitable for address decoding, output selection, and demultiplexing applications in digital systems.
Package: SSOP-16 (5.3×6.2mm) · 16 pins
Why does this need a breakout?
Hand-soldering 0.65mm pitch SMD requires precision tools and steady hands; this breakout board lets you prototype with this 16-pin logic IC using standard headers and breadboards. Ideal for I2C I/O expanders, logic gates, and RS485 drivers where the tiny lead spacing makes direct soldering impractical for development work.
