ST3232EBDR

Product Overview

STMicroelectronics ST3232EBDR is a surface-mount RS232 transceiver in a 16-SOIC package, intended for serial communication interfaces that require full-duplex operation. The device provides two drivers and two receivers, supports a 250 kbps data rate, and operates from a 3 V to 5.5 V supply. Its 500 mV receiver hysteresis and -40°C to 85°C operating temperature range make it suitable for embedded serial link designs where RS232 communication and compact SOIC packaging are required.

Key Features

• RS232 transceiver with full-duplex operation
• 2 drivers and 2 receivers for simultaneous transmit and receive paths
• Data rate of 250 kbps
• Supply voltage range of 3 V to 5.5 V
• Receiver hysteresis of 500 mV
• Operating temperature range of -40°C to 85°C
• Surface-mount 16-SOIC package, 0.154 in (3.90 mm) width

Applications

• Microcontroller serial ports requiring RS232 transmit and receive channels
• Point-to-point serial links between host computers and RS232-compatible equipment
• Serial data interfaces in measurement or control equipment using full-duplex operation

Design & Procurement Notes

Designers selecting the ST3232EBDR should confirm that the board supply falls within 3 V to 5.5 V and that the serial link is consistent with the 250 kbps data rate. The 2/2 full-duplex configuration provides separate transmit and receive channels, which supports bidirectional RS232 wiring. The 500 mV receiver hysteresis and -40°C to 85°C operating range should be considered when evaluating receiver input behavior and environmental conditions. The 16-SOIC surface-mount package requires an SOIC footprint and affects board density and connector placement.
