The Texas Instruments TRS3222CDWR is a multichannel RS-232 line driver/receiver designed for applications requiring robust serial communication. It features two drivers and two receivers, capable of operating at data signaling rates up to 250kbps.
This transceiver provides ±15kV ESD protection on bus pins, exceeding the requirements of TIA/EIA-232-F and ITU v.28 standards. It operates with a VCC supply range of 3V to 5.5V and accepts 5V logic input with a 3.3V supply. The device is housed in a 20-SOIC package and supports surface mount.
Key electrical characteristics include a typical standby current of 1µA and a driver output slew rate of up to 30V/µs. The TRS3222CDWR requires external capacitors, specifically 4 x 0.1µF, for its charge pump circuit. It can be placed in a power-down mode by setting PWRDOWN low, reducing power consumption significantly while keeping receivers active.
Applications for the TRS3222CDWR include battery-powered systems, PDAs, notebooks, laptops, palmtop PCs, and hand-held equipment where reliable serial communication is essential. The operating temperature range is 0°C to 70°C.
