ST232EBTR

Product Overview

The ST232EBTR from STMicroelectronics is an active RS232 transceiver intended for serial communication interfaces that require two drivers and two receivers in a full-duplex configuration. The device operates from a 4.5 V to 5.5 V supply and supports a data rate of 230 kbps. It is supplied in a 16-TSSOP surface-mount package, with an operating temperature range of -40 °C to 85 °C. The supplier device package is listed as 16-TSSOP.

Key Features

• RS232 protocol transceiver with 2 drivers and 2 receivers for full-duplex serial links.
• Supports a data rate of 230 kbps within the specified 4.5 V to 5.5 V supply range.
• Includes a receiver hysteresis value of 500 mV as listed in the supplied specifications.
• Surface-mount 16-TSSOP package with 0.173 in / 4.40 mm width.
• Rated for operation from -40 °C to 85 °C.
• Full-duplex operation is provided by the 2/2 driver and receiver channel arrangement.

Applications

• Full-duplex serial data links between a host controller and an RS232-compatible peripheral.
• RS232 line-level conversion for transmit and receive paths in embedded communication boards.
• Two-channel serial interface support for equipment using separate driver and receiver signal paths.

Design & Procurement Notes

When selecting the ST232EBTR, confirm that the system supply is within 4.5 V to 5.5 V and that the required serial data rate does not exceed 230 kbps. The 2/2 full-duplex channel arrangement supports simultaneous transmit and receive paths, while the 16-TSSOP surface-mount format requires footprint and land-pattern compatibility. The -40 °C to 85 °C operating range and 500 mV receiver hysteresis should be checked against the intended board environment and signal-margin requirements. The listed .
