TISN65C3232DR
Overview
The SN65C3232DR is a high-speed, dual-channel RS-232 transceiver designed for 3V to 5.5V operation. It supports data rates up to 1Mbps, making it suitable for modern high-speed serial communications while maintaining a low typical supply current of 300 microamps. This device is housed in a 16-pin SOIC package, providing a balance of ease-of-assembly and robust performance in industrial environments.
Why Choose This Part
This transceiver offers enhanced ESD protection up to +/-15 kV (HBM) on bus pins, ensuring durability in harsh electrical environments. It allows for 5V logic inputs even when powered by a 3.3V supply, simplifying level translation in mixed-voltage designs. The use of four small 0.1 microfarad external capacitors reduces PCB footprint requirements while maintaining high-speed performance.
Applications
Key Specifications
Getting Started
To integrate this part, place four 0.1 microfarad ceramic capacitors between the charge pump pins and ground as specified in the datasheet. Ensure the SOIC-16 footprint matches the 3.9mm body width for proper solder joint integrity. Verify that the logic-side supply (Vcc) matches your microcontroller's I/O voltage to maintain signal compatibility.
