The SN65C3221EPW from Texas Instruments is a single-channel RS232 transceiver designed for reliable serial communication. It operates with a wide supply voltage range of 3V to 5.5V, making it suitable for various applications. This device supports data signaling rates up to 1 Mbit/s and features robust ±15kV ESD protection on its RS-232 pins, exceeding Human-Body Model (HBM) standards.
Key electrical characteristics include a low standby current of 1 μA typical and the ability to accept 5V logic input with a 3.3V supply. The transceiver integrates a dual charge-pump circuit and requires four small external capacitors (0.1 μF). It also includes an auto-powerdown feature for power savings when the serial port is inactive.
Packaged in a 16-TSSOP, the SN65C3221EPW is designed for surface mounting. Its operating temperature range is -40°C to 85°C, ensuring performance in demanding environments. This transceiver is well-suited for applications such as industrial PCs, wired networking, data centers, and battery-powered systems.
