Detailed Description for ST3232BDR
Product Overview
The ST3232BDR from STMicroelectronics is a full-duplex RS232 transceiver intended for serial communication interfaces. It provides two drivers and two receivers in a 16-SOIC surface-mount package, with a supply voltage range of 3V to 5.5V. The device supports a data rate of 400kbps and specifies 300 mV of receiver hysteresis. Its operating temperature range is -40°C to 85°C. The transceiver integrates the RS232 driver and receiver functions in a single surface-mount device, and the 16-SO package designation corresponds to the 16-SOIC case.
Key Features
- RS232 protocol transceiver with full-duplex operation
- Two drivers and two receivers
- 400kbps data rate
- 300 mV receiver hysteresis
- 3V to 5.5V supply voltage range
- -40°C to 85°C operating temperature range
- 16-SOIC surface-mount package, 0.154 inch (3.90 mm) width
Applications
- Serial data exchange between microcontrollers and RS232-compatible peripherals
- Point-to-point communication links in embedded control boards
- Interface adaptation for 3V to 5.5V logic systems using RS232 signal levels
Design & Procurement Notes
Designers should verify that the board supply remains within 3V to 5.5V and that the serial link is evaluated against the 400kbps data rate. The 300 mV receiver hysteresis can be considered when reviewing input signal transitions in the target RS232 link. The 16-SOIC package supports surface-mount assembly and should match the available PCB footprint. The 16-SO package designation should be used when aligning the footprint with the 16-SOIC case dimensions. The -40°C to 85°C operating range should be checked against the expected ambient conditions of the final assembly.
