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 cascading and demultiplexing applications. Suitable for memory chip select decoding and address decoding with TTL-level inputs. Rated 2.0-6.0V supply, -40°C to +125°C operating range.
Package: TSSOP-16 (4.4×5mm) · 16 pins
Why does this need a breakout?
The 0.65mm pitch makes hand soldering difficult and error-prone; a breakout board lets you solder standard headers instead. This package hosts precision analog and mixed-signal ICs like DACs and ADCs that benefit from clean PCB layouts and decoupling placement. Prototyping becomes faster with breadboard-compatible pin headers, eliminating the need for a custom carrier PCB.
