ST3232ECTR

Product Overview

The STMicroelectronics ST3232ECTR is an RS232 transceiver for serial communication links that require full-duplex operation. The device provides 2 drivers and 2 receivers in a 16-TSSOP surface-mount package, and it operates from a 3V to 5.5V supply. Its specified data rate is 250kbps, and the receiver hysteresis is listed as 500 mV. The supplied lifecycle status is Active, and the operating temperature range is 0°C to 70°C. This device is suitable for board-level serial interface designs where the stated supply range and package dimensions match the circuit requirements.

Key Features

• RS232 protocol support with full-duplex operation.
• 2/2 driver and receiver configuration for simultaneous transmit and receive paths.
• 250kbps data rate.
• 3V to 5.5V supply voltage range.
• 500 mV receiver hysteresis.
• 16-TSSOP surface-mount package with 0.173-inch, 4.40mm width.

Applications

• Configuration, diagnostic, or data-exchange serial ports between a microcontroller and a host computer or terminal.
• Full-duplex RS232 links between two embedded devices that need simultaneous transmit and receive channels.
• Serial interface circuits in measurement or control equipment where a 2/2 RS232 transceiver provides bidirectional communication.

Design & Procurement Notes

When selecting this transceiver, confirm that the board supply is within 3V to 5.5V and that the 16-TSSOP surface-mount package is compatible with the assembly process. The 250kbps data rate and 2/2 full-duplex configuration support bidirectional serial communication, while the 500 mV receiver hysteresis should be considered when evaluating signal integrity at the receiver inputs. The 0°C to 70°C operating temperature range and Active lifecycle status are also relevant to design and procurement planning. Because the device is specified as a full RS232 transceiver, the system serial protocol, data rate, and supply conditions should be checked against the available 3V to 5.5V supply and the 250kbps limit.
