Detailed Description for ST232ACDR
Product Overview
The ST232ACDR from STMicroelectronics is a surface-mount RS232 transceiver intended for serial communication interfaces that require two drivers and two receivers in a full-duplex arrangement. The device operates from a 4.5V to 5.5V supply and supports a data rate of 400kbps, with 500 mV receiver hysteresis. It is housed in a 16-SOIC package with a 0.154 inch, 3.90mm body width and uses surface-mount construction. The operating temperature range is 0°C to 70°C. These characteristics make the part suitable for board-level serial links where an RS232 interface is needed, and the package and supply range support surface-mount integration into electronic assemblies.
Key Features
- RS232 protocol transceiver with two drivers and two receivers for full-duplex serial communication.
- Data rate of 400kbps.
- Receiver hysteresis of 500 mV.
- Supply voltage range of 4.5V to 5.5V.
- Operating temperature range of 0°C to 70°C.
- 16-SOIC package with 0.154 inch, 3.90mm body width.
- Package designation is 16-SO.
Applications
- Serial data exchange between controllers and RS232-compatible peripherals using two transmit and two receive channels.
- Point-to-point serial links in embedded control, instrumentation, or test equipment where full-duplex communication is required.
- Equipment serial ports that need full-duplex RS232 signal conversion within a 4.5V to 5.5V supply range.
Design & Procurement Notes
For design use, the 4.5V to 5.5V supply range should be checked against the system power rail and any voltage-drop margin at the IC pins. The 0°C to 70°C operating range should be checked against the assembly's thermal environment, including nearby heat sources. The 16-SOIC footprint and surface-mount termination affect PCB layout and rework access, while the 400kbps data rate and 500 mV receiver hysteresis are relevant to signal timing and receiver noise-margin behavior in full-duplex RS232 links. Procurement should preserve the exact part number ST232ACDR to ensure the package, supply range, driver/receiver count, and temperature range remain aligned with the design.
