ST232EBDR

Product Overview

The ST232EBDR from STMicroelectronics is a surface-mount RS232 transceiver intended for full-duplex serial interface connections. It provides two drivers and two receivers in a 16-SOIC package, with a 16-SO package designation. The device operates from a 4.5 V to 5.5 V supply and supports a data rate of 230 kbps. Receiver hysteresis is specified at 500 mV, and the operating temperature range extends from -40°C to 85°C.

Key Features

Applications

• serial port connections between microcontroller-based systems and RS232 peripherals
• full-duplex data exchange in instrument control interfaces
• point-to-point communication links in embedded equipment
• serial debugging or configuration interfaces in development hardware

Design & Procurement Notes

Designers should confirm that the system supply falls within 4.5 V to 5.5 V and that the selected RS232 link uses full-duplex signaling with two drivers and two receivers. The 230 kbps data rate and 500 mV receiver hysteresis should be compared with the required serial speed and noise margin. The 16-SOIC surface-mount package and 3.90 mm width affect PCB footprint and reflow handling. The -40°C to 85°C range should be checked against the expected ambient temperature of the board. The 16-SO package designation can help align the footprint with existing 16-SO layouts.
