Detailed Description for ST3232ECDR
Product Overview
STMicroelectronics ST3232ECDR is a surface-mount RS232 transceiver in a 16-SOIC package. It integrates two drivers and two receivers for full-duplex serial communication, with a specified data rate of 250 kbps and a supply range of 3 V to 5.5 V. The receiver input includes 500 mV hysteresis, and the device is rated for operation from 0°C to 70°C. This component is intended for board-level interfaces that connect logic-level serial ports to RS232-compatible signals.
Key Features
- Two drivers and two receivers provide full-duplex RS232 communication.
- Specified data rate of 250 kbps.
- Supply voltage range of 3 V to 5.5 V.
- Receiver hysteresis of 500 mV for input signal robustness.
- Surface-mount 16-SOIC package, 0.154 in, 3.90 mm width.
- Operating temperature range of 0°C to 70°C.
Applications
- Point-to-point RS232 links between microcontrollers and host processors.
- Serial command and data channels in embedded communication modules.
- Legacy serial port interfaces in desktop and equipment-side boards.
Design & Procurement Notes
When selecting ST3232ECDR, verify that the system supply remains within 3 V to 5.5 V and that the serial link does not exceed the specified 250 kbps data rate. The full-duplex 2/2 channel count supports simultaneous transmit and receive paths, while the 16-SOIC surface-mount package requires SMT board assembly. Because the rated operating temperature is 0°C to 70°C, board thermal design and enclosure conditions should be checked against the intended environment. The 500 mV receiver hysteresis is a device characteristic to consider when evaluating input signal margins, but designers should independently evaluate external ESD, cable length, and termination requirements.
