The SN75C3221DBR from Texas Instruments is a single-channel RS-232 compatible line driver and receiver. It is designed to provide the electrical interface between an asynchronous communication controller and a serial port connector.
This transceiver operates with a supply voltage range of 3V to 5.5V and supports data signaling rates up to 1Mbps. It features +/-15kV ESD protection on the bus pins, protecting against electrostatic discharge. The device includes an auto-powerdown feature that automatically disables drivers for power savings when the serial port is inactive, reducing standby current to a typical 1µA.
Key electrical characteristics include a full duplex configuration, 1/1 driver/receiver channels, and receiver hysteresis of 500mV. It accepts 5V logic input with a 3.3V supply. The operating temperature range is from 0°C to 70°C.
The SN75C3221DBR is supplied in a 16-SSOP surface mount package. It requires four external capacitors (0.1µF each) for operation. The device is suitable for applications requiring robust RS-232 communication in a compact form factor.
