The RAA7884QT is a ±16.5kV IEC61000-4-2 ESD protected, 3.0V to 5.5V powered, Quad transmitter designed for balanced communication using the RS-422 standard. With low output leakage currents (±10µA), the driver presents a low load to the RS-422 bus.

The driver (Tx) outputs are tri-statable and incorporate a hot plug feature to keep them disabled during power-up and power-down. The RAA7884QT has a common EN/EN.
