Design a Custom BoardAbout This Component
Dual 2-to-4 line decoder/demultiplexer in 16-TSSOP package. Contains two independent decoders with 2 binary inputs and 4 active-LOW outputs per decoder, plus active-LOW enable pins for demultiplexing capability. Propagation delay typically 11ns (HC) or 13ns (HCT), suitable for memory decoding, address routing, and code conversion applications.
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.
