Design a Custom BoardAbout This Component
Low-power RS-232 transceiver with two drivers and two receivers operating from 3 to 5.5V supplies. Supports data rates up to 250 kbps while maintaining EIA/TIA-232 voltage levels, requiring only four 0.1µF external capacitors. Ideal for battery-powered portable devices, notebooks, and serial communication peripherals.
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.
