Texas Instruments IC TRANSCEIVER FULL 2/2 20SSOP TRS3223CDB

The TRS3223CDB is a multichannel RS-232 line driver and receiver designed for operation with supply voltages ranging from 3 V to 5.5 V. It features two drivers and two receivers, capable of data signaling rates up to 250 kbit/s. The device includes a dual charge-pump circuit that allows it to function with a minimal number of external components, specifically four 0.1 OºF capacitors. Notably, the TRS3223CDB offers robust ESD protection, exceeding ¬±15 kV using the Human-Body Model, making it suitable for applications where reliability is critical. It is optimized for battery-powered systems, including PDAs, notebooks, laptops, and hand-held equipment, with a low standby current of 1 OºA typical. The device also supports flexible power management features, including auto-powerdown capabilities that help conserve energy when the serial port is inactive. Engineers considering this product should note its compliance with TIA/EIA-232-F and ITU v.28 standards, ensuring compatibility with existing RS-232 systems.
