ST3232BTR – 3 to 5.5V 400Kbps RS-232 Driver Interface IC TSSOP-16

Resources:Datasheet
Low-Power RS-232 Transceiver IC with 400kbps Data Rate and 3V5.5V Operation for Serial Communication (TSSOP-16)
The ST3232BTR is a high-performance RS-232 driver/receiver interface IC designed for reliable serial communication in embedded and industrial systems. Operating from a single 3V to 5.5V supply, it provides full RS-232 signal level conversion, making it ideal for interfacing microcontrollers and UART peripherals with legacy serial ports. With support for data rates up to 400 kbps, this IC ensures fast and stable data transmission across communication links.
Featuring a proprietary low-dropout transmitter output stage, the device delivers true RS-232 voltage levels even at low supply voltages, ensuring compliance with EIA/TIA-232 and V.28/V.24 standards. The integrated charge pump requires only four external 0.1F capacitors, simplifying circuit design and reducing component count. Its compact TSSOP-16 package and low power consumption make it suitable for portable devices, industrial equipment, and communication interfaces.
