ST232ABDR

ST232ABDR Description

The ST232ABDR from STMicroelectronics is a robust RS-232 transceiver designed for high-performance serial communication in demanding environments. This surface-mount (SMD) device integrates 2 drivers and 2 receivers, supporting full-duplex communication at data rates up to 400kbps. Operating within a 4.5V to 5.5V supply range, it ensures reliable signal transmission with 500mV receiver hysteresis, enhancing noise immunity in electrically noisy conditions. Packaged in a 16-pin SOIC and delivered in Tape & Reel (TR), it complies with ROHS3 and REACH environmental standards, making it suitable for modern, eco-conscious designs.
