TRS3223CDB Description

Short technical summary and product information.

The Texas Instruments TRS3223CDB is a multichannel RS-232 line driver and receiver designed for 3-V to 5.5-V VCC supply operation. This transceiver integrates two line drivers, two line receivers, and a dual charge-pump circuit with ±15 kV ESD protection. It meets or exceeds the requirements of TIA/EIA-232-F and ITU v.28 standards, providing a robust electrical interface for asynchronous communication controllers.

 

The device operates at data signaling rates up to 250 kbit/s and offers flexible power management options, including an auto-powerdown feature that reduces standby current to a typical 1 µA when the serial port is inactive. It accepts 5-V logic input with a 3.3-V supply, making it suitable for mixed-voltage systems. The TRS3223CDB is available in a 20-SSOP package and is designed for surface mount applications.

 

Key features include ±15 kV ESD protection on bus pins, operation from a single 3-V to 5.5-V supply, and a low standby current. The device is suitable for battery-powered systems, PDAs, notebooks, laptops, and other hand-held equipment requiring reliable serial communication.
