Design a Custom BoardAbout This Component
True RS-232 transceiver with 2 drivers and 2 receivers operating from 3.0V to 5.5V single supply. Features integrated charge pump requiring only 0.1µF capacitors, 250kbps transmission rate, and ±15kV ESD protection. Includes low-power shutdown mode with <1µA quiescent current. Ideal for portable and handheld devices requiring standard RS-232 serial communication.
Package: TSSOP-20 (4.4×6.5mm) · 20 pins
Why does this need a breakout?
Hand-soldering 0.65mm pitch leads is tedious and error-prone; a breakout board with standard 0.1" headers lets you prototype I/O expanders and logic gates on breadboards without a reflow oven. The compact SSOP package also becomes DIP-friendly, eliminating jumper spaghetti and reducing assembly mistakes during development cycles.
