ST232EBDR

ST232EBDR Description

The ST232EBDR from STMicroelectronics is a high-performance RS-232 transceiver designed for robust serial communication in industrial and embedded systems. This surface-mount (SMD) IC integrates 2 drivers and 2 receivers, supporting full-duplex communication at data rates up to 230kbps. Operating within a 4.5V to 5.5V supply range, it ensures reliable signal transmission with 500mV receiver hysteresis for noise immunity. The device complies with ROHS3 and REACH environmental standards, packaged in a 16-pin SOIC (Tape & Reel) for automated assembly. Its Moisture Sensitivity Level (MSL 3) ensures durability in humid conditions.
