The Texas Instruments TRS3223CDBR is a multichannel RS232 line driver/receiver designed for 3-V to 5.5-V VCC operation. It provides the electrical interface between an asynchronous communication controller and the serial port connector.
This transceiver features two drivers and two receivers, supporting a data rate of up to 250kbps. It operates within a temperature range of 0°C to 70°C and requires external capacitors for its dual charge-pump circuit. The device meets or exceeds the requirements of TIA/EIA-232-F and ITU v.28 standards.
Packaged in a 20-SSOP surface mount configuration, the TRS3223CDBR is suitable for various applications requiring RS232 communication. It offers flexible power management options, including auto-powerdown when the serial port is inactive, reducing standby current to a typical 1μA.
Key electrical characteristics include a receiver hysteresis of 500mV and ±15kV ESD protection on bus pins. The device accepts 5V logic input with a 3.3V supply, making it versatile for mixed-voltage systems.
