Design a Custom BoardAbout This Component
3-to-8 line decoder/demultiplexer IC that converts three binary address inputs (A0–A2) into eight mutually exclusive active-LOW outputs (Y0–Y7). Features three enable inputs for easy cascading and demultiplexing capability. Operates from 2.0V to 6.0V with TTL-level inputs (HCT variant), ideal for memory chip select decoding and address decoding applications.
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.
