Single-Channel RS-232 Transceiver IC with 3V–5.5V Operation, Low Power and +-15kV ESD Protection (TSSOP-16)
The TRS3221EIPWR is a reliable single-channel RS-232 transceiver IC designed for interfacing microcontrollers and digital systems with standard serial communication ports. Operating from a wide 3V to 5.5V supply range, it integrates one driver and one receiver, making it suitable for compact embedded designs requiring efficient UART to RS-232 level conversion. The device supports data rates up to 250 kbps, ensuring stable and accurate communication across various applications.
Featuring an internal charge pump, the IC generates the required RS-232 voltage levels using only external capacitors, eliminating the need for dual power supplies. It also offers robust +-15kV ESD protection on RS-232 pins, enhancing system durability in harsh environments. With low power consumption and a compact TSSOP-16 package, the TRS3221EIPWR is ideal for portable devices, industrial communication systems, and embedded serial interfaces.
