Design a Custom BoardAbout This Component
Dual 2-to-4 line decoder/demultiplexer in 16-pin TSSOP package. Converts two binary address inputs into four mutually exclusive active-low outputs. Features TTL-compatible logic levels and typical propagation delay under 30ns. Commonly used for address decoding, output selection, and multiplexing applications in digital circuits.
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.
