The SN75C3221PWR is a single-channel RS-232 line driver and receiver from Texas Instruments, designed for reliable serial communication. It operates with a wide supply voltage range of 3V to 5.5V, making it versatile for various applications. This transceiver supports data signaling rates up to 1 Mbps and includes ±15 kV ESD protection on its bus pins, safeguarding against electrostatic discharge.
Key features include a low standby current of 1 µA typical and an auto-powerdown function that conserves energy by disabling drivers when not in use. It accepts 5V logic input with a 3.3V supply, offering flexibility in system design. The device requires four small external capacitors for its dual charge-pump circuit.
Packaged in a 16-TSSOP, the SN75C3221PWR is suitable for surface mount applications. Its operating temperature range is from 0°C to 70°C. This transceiver provides the necessary electrical interface between an asynchronous communication controller and a serial port connector, making it a robust choice for embedded systems and industrial communication interfaces.
